Hi Marty. I enjoy the channel and recently picked up a high mileage 06 IS 350 that I'm bringing back after a life of neglect. A couple of notes for you to consider: - Always remove the fill plug first. If you remove the drain plug and can't get the fill plug off you're in a heap of trouble - The solution to pollution is dilution. I would run the new fluid in for 1000 miles, drain and replace again and continue until all of the fluid has been replaced - Transmission capacity is actually close to 9 quarts. You could do this 3 times to slowly replace everything - It's a good idea to not only warm the transmission to 104 degrees but to also shift the car from Park to Drive and all stops in between for 3 seconds at each point - If you don't have a scan tool, you can measure the temperature of the trans with an infrared thermometer. These are inexpensive and readily available - It's a good idea to drain the old fluid into a see through container, mark the level and replace exactly that amount. I really enjoy the channel and like the tasteful mods to your IS. I've enjoyed watching the car progress from when you first bought it. Keep up the great work!
Forget the IR thermometer. There is a way to jumper two obd pins and it forces you to shift the trans too. When they blink or something you are at the right temperature.
@@armandol1826 I have recently bought two of them. $4000 for a very clean white is350 loaded 170k miles with clean title. $7800 for a clean title blue 2007 lexus is350 with 101,000 miles. These cars are an absolute bargain for what they are.
Pro tip: unscrew your fill plug before your drain. I could go into the “scientific sounding” terms of why, but the practical explanation is that you don’t want to drain your transmission and not be able to fill it back up again.
Brandin Sanchez No, if you drain your trans and then not be able to fill it back up you’re fucced. So to be safe, make sure you can even take out the fill plug before draining to prevent that “oh shit” moment
@@brandinsanchez1907 What he is saying is to remove the fill plug BEFORE removing the drain plug. The reason being that if you remove the drain plug first but are unable to remove the fill plug, you won't be able to refill your transmission. Meaning, you can't drive it without risking damage.
@@JT-sk5nw This actually saved me.

Is250 owner here and changed my transmission fluid at 120k miles. Drain and fill and filter change. I intend to do this again at 200k Miles or every 80k miles to keep the transmission strong and dependable.
@@KingDrewPhilip did they change the transmission filter as well? I jus got mine (2009) with the same mileage as yours. How much quarts did you drain and fill?
Just did mine today for the IS250. Gasket seal and filter with 5Litres of oil. There is a difference. Smoother. Old fluid when it came out was dirty black. New nice and red of course. Aisin OEM oil. Lexus IS250 2.5l rear wheel drive 2007 here in the UK. If anyone wants a recommendation. Get it done trust me. If you want your car forever just do it your gearbox will be like new. Got it done from Thurrock gearbox oils LTD for £287 parts, oil and labour. Watched the whole process they are only really doing transmission stuff really. Took about 1 hour.
Today i did my Lexus IS250 rwd automatic transmission oil, i only drain the oil from transmission pan and i refill 4 quarts exact! I’ve used Valvoline fully synthetic ATF
Lexus says temperature should be between 104-114 degrees when you use the overflow tube to set level. If it is too hot it will expand the fluid and you will drain too much. Thanks for the video.
Props to actually doing this service. It is commonly neglected. It should be noted to first break free the fill port. Better to make sure that's going to come off than draining and finding out you can't add new fluid.
This is great advice, everyone with a high mileage "lifetime" fluid transmission should do this. Some people may be scared of doing this, but it is NOT a flush which like he said in the video could potentially be harmful...you're simply doing a gravity drain and replacing whatever comes out with fresh fluid. This method is harmless as long as you dont strip out your drain and fill plug threads, use the wrong fluid or dont refill it with the correct amount. I used to have a 2016 GTI with the DSG...doing the fluid/filter service at 40k miles made it seem new again. Even a regular slushbox can benefit from fresh fluid and a new filter...just dont try flushing or adding any funky cleaner fluids that arent the original spec trans fluid.
What if I bought a lexus and don’t know what fluid they used before and I wanna use whatever i buy? Will i still be able to put a different fluid in there or do I have to do a full flush?
I was happy that someone finally made a drain and fill on an IS, but I remembered that my car was an 2009 IS250 and it doesn't have that drain plug much as the fill plug like the IS350.
I came across this video by chance and Im blown away! Great video, very good and detailed instructions about how to change the A/T oil at home. Now I have to dig through your channel to see all the Lexus related videos :) And I should probably buy a Toyota Techstream diag tool for some tinkering. So thanx for the inspiration, keep up the good work! ;)
I do a transmission pan drain and fill about every 5th oil change to all my vehicles. Have over 200k miles on both vehicles and no transmission issues what so ever. Started doing this at 65k miles. The folks that never change their trans fluids are the ones with transmission issues.
@ work what i do is drain the fluid into an empty washer fluid bottle. then i match what came out to my pump and add a tad extra to compensate. allows me to skip the over fill process.
I just changed mine at 74K miles, it was pretty darn dirty. I did the strainer/filter, gasket and 5 Quarts. I doubt all those Quarts were able to mix with the old fluid to help push it out, but thought the more I did this one time the better. And now I cross my fingers lol.
I’m very busy so I’m watching your video by parts hahaha ! My car also had the abs,vac, and check engylight, cus of Evap leak a little hose that’s next to the air intake pipe close to the battery that was my problem. Take care Martin keep making more videos
Yes, assuming it was at the proper levels beforehand. Though I would not recommend overfilling it to that degree. You can kind of think of it like the drain and fill plug on a differential, except in this case it needs to be at a certain temperature beforehand with the engine running.
For your vsc light if you have changed your engine air filter recently check the little hose that runs under your air intake from filter compartment to the intake when that comes out I usually get the vsc on my info to come on also. Reconnect it and usually goes away
my daughter has a 2015 lexus gs350 f sport with 45,000 miles. son has is250 awd with 125,000 miles on it. will be doing son's car. video was very helpful
At the dealership, we drain the transmission fluid through the drain plug and with the engine at operating temperature we fill it back in through the check plug while it's running. Once it starts leaking out we stop and tighten it back.
I have a Lexus 2014, model Es250. Unfortunately, I haven't changed the transmission oil, since I bought the car. The car is a single owner, and it currently has 180, 000 km.. The agency says that if they change the oil, they won't guarantee the transmission or the repairs. Some mechanics say that I can change the oil with no problems to the transmission, others say that it is a high risk. What can you recommend? Thanks!
Is just bought a 2012 is250..with 80.000 miles...do you recommend the transmission flush..with a fresh new oil..just as you did to yours...any suggestions please..thumbs up for your great video..👍👍
Marty, can I confirm that you had the engine running during the overfill drain? Were you idling in Park/Neutral or did you have it in gear? I recently did 3 consecutive drain/refills on my daughter's IS350 (running thru the gears and getting it up to temp each time) and it was rewarding to see the fluid get progressively cleaner each time. I did the overfill drain with it idling in gear, after stepping thru each gear and reverse (to fill the valve body). I hope this was right!
Yup the engine was running! I gave it about 5 minutes to get up to temp after a cold start, but didn’t cycle the gears. Our tool showed the trans temp was where it needed to be so I went for the overfill plug, and a good amount came out. This could also be because I put 3 full quarts in, when really only 2.5 came out. Sounds like you’re doing it right! I may do it again in the future
You don't have to shift the car in gears after changing the fluid. Also you don't have to check the temp with any computer or infra-red meter. Run the car for 15-20 minutes. It will be hot enough. Anything extra in the trans will come out through the overflow drain. I had a guy put 4 quarts of transfluid in after draining 1.5 quarts in his. He ran it like that for 6 months. Do not do this. Generally 1.5 to 2 quarts will come out through drain. What ever you take out put a half a quart on top of what came out. Let it run. Then open the overflow. Best thing about these cars is they they have ways to keep you from messing up if you do it right
Really the filter is just a strainer for larger particles like metal shavings (which are also caught by the magnets), the smaller particles you remove with the fluid change pass right through the filter anyway as it's not as restrictive as an oil filter so unless you need to replace the pan gasket because of a leak there is little point in doing the extra labor and cost of changing the ATF filter.
@@lecahier yes it shifts a lot quicker. I drove it for about 500 miles and repeated to get better fluid in there. Mine was disgusting when I changed it.
@@jovangarrison6337 what was your procedure? I was to do it my self , so you drain and then fill about 3qts and let it warm Up parked for about 15 minutes and turn off car and open overflow ? Just curious since you done it twice and I am new
Marty Motoring that’s right, I actually had to subscribe to their club membership in order to get it , my experience was great , the shifts are way more smooth , my car is a 07 is350 has 120,000 miles and I was lucky to get it for only 7k with the original spark plugs , alternator, air filter and of course the trany fluid , i already swap everything new everything now she’s really fast
I wanted to do this. But My idea is do like what you mentioned do several drain and refills in order to clean up debris allowing the old filter to catch it then I was going to drop the pan and put a new filter on for better flow. Bu that time i should have replaced majority of the older oil.
@@MartyMotoring I got my transmission fluid changed and it makes a big difference. Shifts much smoother. I was nervous at first. I have 117k miles on it. It used 4 Qts drained and filled. Thanks for all your great videos!!
@@MartyMotoring some ppl say that if u change the transmission oil is going to slip and will break so I haven't change my transmission oil since I bought my is 250 2007 150k miles
My trans was redlining in 4th going up hills on the down shift in cruise. Got it changed last week, runs like dream now. Worth doing. Mine had the original fluid. Mechanic said it was like mud. After 11 years and 220k I suspect it would be. Than again if your not having problems than don’t touch it
Good video! I'll be doing this on my 08' ES 350 this spring which has ~134,000km(83200miles). But the observant type I am, I noticed your "Check VSC" notification was on. Other problems?
Hey Marty, when do you suggest I do the transmission change? I also have no ATF vehicle history on my car but my transmission shifts smooth and like a dream with 205k miles. Do you suggest I do the change when it’s performance is starting to degrade or should I do it as soon as possible? Thanks and keep up the great content
Many mechanics recommend to drain and fill ever 30,000 miles, If you don't know the service history it's best to do all the required maintenance items as if none were ever done included the transmission oil change. Better safe then sorry. I do that with every used car I buy.
I have a 2010 IS 250 I bought it at 101,500. I removed the trans pans, drained all the fluid over night. Changed the trans filter inside, cleaned the pan completely. Installed a new Tran gasket. At 101 miles the oil was black. Toyota says don't do it this way because you have to fill the exact amount you take out & most don't count quarts taken out, I do. Now there's no metal shaving in the pan or any old fluid left. I noticed the smooth shits in the first 100 ft driven.
Nice - I may do that when I have the time, but this is my daily driver as of now so I can’t have it down for any amount of time with work. That’s why I introduced new fluid into the system, and used the overfill plug to drain any excess fluid, as per the Toyota and Lexus techs I talked to. So far it works great and shifts smoother. The fluid is still brown, but next time I’ll do the filter, gasket and all new fluid. For now with 170k, the car runs great
G 36 changing all the fluid and filter isn’t a flush. A flush is using special equipment to flush everything through the system via the trans cooler, which lets all the dirt and particles go all over the system, which isn’t the best idea for high mileage cars
If you put in the exact amount that came out, why do you need to check the level? Or why would there be overflow? I'm about to do this to my 2007 Tundra and I'm just curious when the level needs to messed with when replacing the same amount you took out?
ATF volume expands and contracts with temp changes. Rather than ASSUME the level is correct it is better practice to do a final fluid level check (verification) as Toyota/Lexus recommends. After draining out the old, put in the same amount new plus a half quart. Start the engine slowly shift gears up and down with 3 second pauses to fully distribute ATF through all the nooks and crannies. When temp gets up to (40-45 Celsius) = 104-113 Fahrenheit you should then remove the level check plug and then replace it (with new crush washer = Torque 15 Ft lbs) as soon as the drain slows to a dribble. Then you will be ASSURED you have the correct amount.
Do you leave the engine running when you open the overfill plug? Coz I'm thinking, on any trans that have dipstick ,you check the fluid while the engine is running and trans in park at normal operating temperature.
Just 7ndo the top transmission cooler line. Attach a rubber hose. Add 4 quarts of fluid and idle the engine. When clear red fluid comes out of the hose stop. Fill to proper level. Good to go
My 08 is350 has about 80k miles, should I do a drain and fill or wait a bit longer? (How often should you do this to improve longevity/smoothness of shifts)
How many quarts are in the transmission at full capacity? One drain/fill seems like you might only be replacing 1/4 to 1/3 of the fluid. I'd want to repeat it!
I have a 2017 IS300 F Sport. I’m not the original owner but the car has 68k miles and I decided to change the transmission fluid. The fluid was dirty and smelled bad. Do u think I damaged my transmission by changing being the oil was that bad??
What’s up bro. Would you recommend adding Lucas Transmission Oil Additive to my 2006 Lexus Is250 Automatic Transmission. It doesn’t shift hard or any super bad problems. I’ve just noticed it sometimes take a while to shift. Like laggy. Or should a simple oil n filter change should be sufficient?
whats the millage to change? just got one with almost 150k dont know if its a good idea . always heard if its below 80k yes but after 100k its better to leave it alone
Recommended every 6 years or 60k miles for transmission fluid. With that many miles you definitely do NOT want to replace ALL the fluid. You may remove all the friction material that keeps it shifting fine. At most a drain and refill, but I'm not sure.
Great video … is have the 2006 is250 AWD I’m wondering if the the only oil by the gear box of front or is it only the aft-ws and the differential in the back 76w85?
Great video n straight to the point, I’m happy you notice some difference in shifting, I’m doing my second drain n fill but using Amsoil this time, nothing wrong with ws Toyota don’t get me wrong, but after seeing some contents and videos on ws Toyota doesn’t hold up as Amsoil signature series, so I decided the switch. Subscribed to your channel 🤟🏼
@@MixDoctaD switched back to WS Toyota and did 2 drain n fill very happy with the result, reason that I switch back because I tried Amsoil engine oil and didn’t get a good result and my car start smoking and my cabin was smelling oil all over so I decided to switch to WS Toyota and decided to return everything I received from Amsoil 👍🏼 hope this help
I understand that the amount of “excess” fluid that comes out at operating temperature will be too much and will leave the transmission low on fluid, causing damage to the transmission. At least for their newer 6 and 8 speed transmissions. For operating temp excess removal there is a longer straw that has to be used to drain correct amount. So crazy. Even Lexus service shops won’t run the procedure.
Never had issues doing a drain/replace with that many miles? I am getting one with 80k miles and was thinking of just going ahead and doing it now as preventive maintenance.
My Is250 is at 190,000 miles..I bought the car at 145,000 miles..it’s been rock solid.. my question is for anyone who can answer..do you guys recommend a drain and fill at this mileage..I can’t find records of the tranny being serviced..and as of now, the tranny shifts like butter..any advice would be appreciated..I plan on taking it to the dealer this upcoming weekend..they quoted me $350 for the service..I’m very nervous
Jordan Swadberg still going strong at 205,000 miles..servo motor is going out on passenger side..will cost over 1,000 dollars..but everything else is fine
Jordan Swadberg sorry I just read you’re question..did a drain a fill in October of last year..feels just fine..was very dirty but the technicians said the fluid did not smell burned. It was a good service, can’t really feel a difference when driving . Tranny only feels weird in cold morning drives..it revs higher but most IS250/is350’s do that. Still rock solid under the hood but I have feeling the electronics will soon be having issues but only time will tell.
Do you know if this process is relatively the same for the Lexus ISF? Considering doing this on my car ... car shifts fine just wanna make sure I’m keeping the car as fresh as possible
Be aware, different vehicles can vary widely between the check/overflow temperature range. For example, my car states the ATF needs to be between 104-113 degrees Fahrenheit, HOWEVER, my girlfriends car says the ATF needs to be between 185-203 degrees Fahrenheit!!! Also, my operating temperature in my car is easily 50 degrees hotter than the maximum range. Just food for thought.
If you do the under glow , just put one strip under your front bumper and rear , all white neons , it won’t be ricey as long as it’s not changing colors lmfaoo
I would just use the same type fluid it was originally filled with to be safe, but you could ask a Toyota tech (or two) if adding synth would be compatible with the fluid that remains in the tranny.
Thanks bro I need to do this ASAP and let me know about the head lights Bcuz I’m gonna upgrade my lights too but I don’t want my afs light flashing on the dash .
Also check at the start that you can unscrew the overfill plug, if it's stuck you could have overfilled and have no way to get it back down to the correct level.
Great video! I just have a question. i have the exact same vehicle 168k miles, and i am unsure about any prior Trans fluid changes. I recently found a slow leak from the fluid pan gasket and i am curious if i can do this same thing but change the gasket at the same time? thx
Hey I’ve got a 2007 gs350 love the car but started to notice it’s burning oil quickly. About 1.5qt every 1500 miles. And saw some smoke out of the exhaust last week blueish grey. Car has been dealer maintained since new oil changes every 5k. I’ve got 147k on the car does yours burn oil or smoke at all? Thanks man!
I have to do this to my 350 if I brake hard I get a pretty good cluck from the trans down shifting. I think I will do the filter also just to be safe because if that fluid is that dark the filter has to be in bad shape.
When you felt the clunk was it under hard braking? Because my trans down shifts pretty slow under hard braking. Just wondering if that is what you had going on and the new fiuld fixed it.
Also got VSC after cleaning wires contacts of spark plugs and sensors with rubber seal protection. Got Check engine lite, and misfire cylinder 2. And port injector error. P1277 P0302 After I've discovered that one of three wires from the camshaft position sensor has lost contact. It was only punched to the connector. And I've interrupted the contact when did the procedure. If the camshaft sensor was sending incorrect signal to the computer. Then the computer doesn't send a spark to coil. Today ive got a new connector. Replaced it. Clean codes. So far no check engine. Be careful, if you are not the original owner. Someone before you possibly did a goofy job.
Hm interesting! I have had the car for almost 2 years now...but I recently did spark plugs myself with no issues or check engine light. My Toyota software tells me the VSC is due to my right front ABS sensor. So just gotta replace that soon!
Hey Marty, (or anyone else who knows or has advice) do you have any personal tips for me? I have a 2006 Lexus is250 awd and it isn’t grinding or jerking at all, but it is shifting rough mostly almost in all gears not too bad but enough for me to take action on it, I’m thinking about going to do a drain and fill to see if that helps and/or fixes but it has shifted fine before, but the trans was never serviced for a change or flush and I’m at 163,000 miles so I reckon new fluid would be good, I’m just worried my trans is damaged but like I said it isn’t as bad as others I have heard of, I just want to know what anyone thinks, I have seen many Toyota/Lexus vehicle with unchanged fluid at 100k-200k miles with no change once and people changed fluid and it fixed it and made it feel better than ever, I know of the it will damage a transmission thing but idk if its a myth with Toyota/Lexus. I know this is long and someone may not read this but if someone does any help would be appreciated
Just do a drain and fill. Should be between 2-3 quarts unless you drop the pan, than it will probably be 6-7 quarts. I can report after having my transmission serviced that the car is way smoother and faster believe it or not. Just make sure the tech examines the fluid for metal shavings or burnt fluid which has a very distinctive smell. My tech said my fluid was so dirty, I shouldn’t have it serviced anymore. I don’t know what to say about that but, if you’re tranny is shifting rough, have it serviced before it gets worse. Usually when you’re tranny starts having issues, it’s pretty much toast, but that’s not always the case. Good luck to you, and I hope you’re car lasts another 200,000 miles. 🤞
@@kingdrosive4102 Dropped the pan and done it. Filter. Gasket seal. 5 litres of oil went in. Specialist did it. Very smooth now. It was before but even better believe me. Car pulls better.

@@kingdrosive4102 Paddle shift mode shifts down or up when it feels like your about to do something dumb. 2nd gear never holds. But tbf in my scenarios it does make sense to use 1st just would prefer it to maintain 2nd more on some occasions
would it be simpler to capture the old fluid and fill the transmission with the exact same amount that was taken out? With that simpler method, you won't have to worry about jacking up all four corners to keep the car perfectly flat.
The only way that works is if the car has sat overnight or long enough to where the Trans is the same temp as ambient (as the jug of new fluid is) because Trans fluid expands at different temps.

Why wait till 200k? Makes no sense to wait that long since a drain and fill only displaces 2-3qts (out of 11).
I'm a southpark fan, too...Also, don't Forget to open the fill-plug first ;) If that's stuck, you're stuck.
Just did mine today for the IS250. Gasket seal and filter with 5Litres of oil. There is a difference. Smoother.

Please do a rear diff drain/fill video next!
Thanks for the upload.
You can jumper two obd pins and it tells you when you are up to temperature. There is a procedure.
Follow the same steps as a 4th generation Toyota 4Runner or Tacoma. You get underneath the car and all sensors and parts say Toyota on a Lexus.
Rear Differential fluid is very simple and straightforward. DM me for information on doing it if you'd like.

Do you face any problems after that’s?
Lexus says temperature should be between 104-114 degrees when you use the overflow tube to set level. If it is too hot it will expand the fluid and you will drain too much. Thanks for the video.
Props to actually doing this service. It is commonly neglected. It should be noted to first break free the fill port. Better to make sure that's going to come off than draining and finding out you can't add new fluid.
darth420vader *Oh Good thinking 👀👍🏽👍🏽*
You can actually add fluid through the overflow port with a $10 hand fluid pump. So it's not a big deal on these Lexus/Toyota models.
Unless that port is also stuck and you didn't check it first either.
@@ruthnoya8424 Good luck with that.
One thing that i HIGHLY recommend is to always unscrew fill and over-fill plugs first. You never know if the plugs snap or not.
This is great advice, everyone with a high mileage "lifetime" fluid transmission should do this. Some people may be scared of doing this, but it is NOT a flush which like he said in the video could potentially be harmful...you're simply doing a gravity drain and replacing whatever comes out with fresh fluid. This method is harmless as long as you dont strip out your drain and fill plug threads, use the wrong fluid or dont refill it with the correct amount. I used to have a 2016 GTI with the DSG...doing the fluid/filter service at 40k miles made it seem new again. Even a regular slushbox can benefit from fresh fluid and a new filter...just dont try flushing or adding any funky cleaner fluids that arent the original spec trans fluid.
What if I bought a lexus and don’t know what fluid they used before and I wanna use whatever i buy? Will i still be able to put a different fluid in there or do I have to do a full flush?
I was happy that someone finally made a drain and fill on an IS, but I remembered that my car was an 2009 IS250 and it doesn't have that drain plug much as the fill plug like the IS350.
I have the same car, have you found a video for that year and model that's helpful?
I have a 2011 IS250. What does it have under there exactly?
it’s the same wdym
Please no under glow i beg you
LOL
Wat is under glow

I came across this video by chance and Im blown away! Great video, very good and detailed instructions about how to change the A/T oil at home. Now I have to dig through your channel to see all the Lexus related videos :) And I should probably buy a Toyota Techstream diag tool for some tinkering. So thanx for the inspiration, keep up the good work! ;)
Thanks for the vid! You have no idea how terrified to change my fluid, I was scared it would be worse afterwards. I’m definitely going to do it now
How did it go?
I do a transmission pan drain and fill about every 5th oil change to all my vehicles. Have over 200k miles on both vehicles and no transmission issues what so ever. Started doing this at 65k miles. The folks that never change their trans fluids are the ones with transmission issues.
Glad to know im change my oil
You think I’d have issues just changing once. Mine has 95k miles
@ work what i do is drain the fluid into an empty washer fluid bottle. then i match what came out to my pump and add a tad extra to compensate. allows me to skip the over fill process.
Nice! That’s what I’ve done on the 2 ISes I’ve had since this one 😂 Works well! Just did it on the ISF. Put exactly what came out
I do a pan drain and fill about every 5th oil change.
No underglow. Don't rice it out.
It would definitely be unique but not my style lol.
I just changed mine at 74K miles, it was pretty darn dirty. I did the strainer/filter, gasket and 5 Quarts. I doubt all those Quarts were able to mix with the old fluid to help push it out, but thought the more I did this one time the better. And now I cross my fingers lol.
I’m very busy so I’m watching your video by parts hahaha ! My car also had the abs,vac, and check engylight, cus of Evap leak a little hose that’s next to the air intake pipe close to the battery that was my problem. Take care Martin keep making more videos
How does the overflow work? Lets say if i drain out 2 quarts and i put in 4 would 2 quarts come out of the overflow?
Yes, assuming it was at the proper levels beforehand. Though I would not recommend overfilling it to that degree. You can kind of think of it like the drain and fill plug on a differential, except in this case it needs to be at a certain temperature beforehand with the engine running.
Smart move. I do this with my IS250 every 50k, just a simple drain and fill and the car shifts perfect
Can you do it without a lift?

You should also change the tranmission filter that often
When opening the overflow those it require for the car to be on or driving some ?
For your vsc light if you have changed your engine air filter recently check the little hose that runs under your air intake from filter compartment to the intake when that comes out I usually get the vsc on my info to come on also. Reconnect it and usually goes away
my daughter has a 2015 lexus gs350 f sport with 45,000 miles. son has is250 awd with 125,000 miles on it. will be doing son's car. video was very helpful
At the dealership, we drain the transmission fluid through the drain plug and with the engine at operating temperature we fill it back in through the check plug while it's running. Once it starts leaking out we stop and tighten it back.
This is what I needed to see 😆 someone that's not lying to us about this Lifetime Fluid bs
I have a Lexus 2014, model Es250. Unfortunately, I haven't changed the transmission oil, since I bought the car. The car is a single owner, and it currently has 180, 000 km.. The agency says that if they change the oil, they won't guarantee the transmission or the repairs. Some mechanics say that I can change the oil with no problems to the transmission, others say that it is a high risk. What can you recommend? Thanks!
Is just bought a 2012 is250..with 80.000 miles...do you recommend the transmission flush..with a fresh new oil..just as you did to yours...any suggestions please..thumbs up for your great video..👍👍
If it shift smooth then no Lexus don't recommend changing them at all
Do it before it starts to act up
Use amsoi signature series fluids in the transmissions, differentials, transfercase,etc
Marty, can I confirm that you had the engine running during the overfill drain? Were you idling in Park/Neutral or did you have it in gear? I recently did 3 consecutive drain/refills on my daughter's IS350 (running thru the gears and getting it up to temp each time) and it was rewarding to see the fluid get progressively cleaner each time. I did the overfill drain with it idling in gear, after stepping thru each gear and reverse (to fill the valve body). I hope this was right!
Yup the engine was running! I gave it about 5 minutes to get up to temp after a cold start, but didn’t cycle the gears. Our tool showed the trans temp was where it needed to be so I went for the overfill plug, and a good amount came out. This could also be because I put 3 full quarts in, when really only 2.5 came out. Sounds like you’re doing it right! I may do it again in the future
Would it generally be a good idea to shift through the gears before doing the overfill-check?
Yes, it's part of the transmission service procedure
This is a REALLY good guide, thank you for sharing this.
You don't have to shift the car in gears after changing the fluid. Also you don't have to check the temp with any computer or infra-red meter. Run the car for 15-20 minutes. It will be hot enough. Anything extra in the trans will come out through the overflow drain. I had a guy put 4 quarts of transfluid in after draining 1.5 quarts in his. He ran it like that for 6 months. Do not do this. Generally 1.5 to 2 quarts will come out through drain. What ever you take out put a half a quart on top of what came out. Let it run. Then open the overflow. Best thing about these cars is they they have ways to keep you from messing up if you do it right
Also make sure the car is level. When it's on the hoist it might not be level.
Thanks for this vid Marty but why not change the filter??
I probably will eventually but didn’t want to drop the pan and order the filter which would delay the fluid change
Marty Motoring hey do you know what songs you put in the video ??
I just passed 100k miles in my 06 is350, time for me to change trans fluid as well.
Really the filter is just a strainer for larger particles like metal shavings (which are also caught by the magnets), the smaller particles you remove with the fluid change pass right through the filter anyway as it's not as restrictive as an oil filter so unless you need to replace the pan gasket because of a leak there is little point in doing the extra labor and cost of changing the ATF filter.
Thanks for the video. Mines been a little jerky on the downshift so I think I’m gonna do this too.
Did you do this and did it help the downshifts? Having the same issue.
@@lecahier yes it shifts a lot quicker. I drove it for about 500 miles and repeated to get better fluid in there. Mine was disgusting when I changed it.
@@jovangarrison6337 what was your procedure? I was to do it my self , so you drain and then fill about 3qts and let it warm Up parked for about 15 minutes and turn off car and open overflow ? Just curious since you done it twice and I am new
Remember to remove fill plug first next time
This.
I was going to do drain my rear diff fluid and Rememeber to start with the fill bolt and I couldn't get it off. Saved myself a major headache.
I did my transmission oil fluid exchange with amsoil sintético
Amsoil is good stuff!
Marty Motoring that’s right, I actually had to subscribe to their club membership in order to get it , my experience was great , the shifts are way more smooth , my car is a 07 is350 has 120,000 miles and I was lucky to get it for only 7k with the original spark plugs , alternator, air filter and of course the trany fluid , i already swap everything new everything now she’s really fast
I wanted to do this. But My idea is do like what you mentioned do several drain and refills in order to clean up debris allowing the old filter to catch it then I was going to drop the pan and put a new filter on for better flow. Bu that time i should have replaced majority of the older oil.
Good video! I hope you don't have future problems with the transmission.....
So far it’s great
@@MartyMotoring I got my transmission fluid changed and it makes a big difference. Shifts much smoother. I was nervous at first. I have 117k miles on it. It used 4 Qts drained and filled. Thanks for all your great videos!!
@@MartyMotoring some ppl say that if u change the transmission oil is going to slip and will break so I haven't change my transmission oil since I bought my is 250 2007 150k miles
My trans was redlining in 4th going up hills on the down shift in cruise. Got it changed last week, runs like dream now. Worth doing. Mine had the original fluid. Mechanic said it was like mud. After 11 years and 220k I suspect it would be. Than again if your not having problems than don’t touch it
Another great video. Thanks Marty.
Good video! I'll be doing this on my 08' ES 350 this spring which has ~134,000km(83200miles). But the observant type I am, I noticed your "Check VSC" notification was on. Other problems?
Yeah for me the that light came out turns out it was my fuel injectors
Hey Marty, when do you suggest I do the transmission change? I also have no ATF vehicle history on my car but my transmission shifts smooth and like a dream with 205k miles. Do you suggest I do the change when it’s performance is starting to degrade or should I do it as soon as possible? Thanks and keep up the great content
Many mechanics recommend to drain and fill ever 30,000 miles, If you don't know the service history it's best to do all the required maintenance items as if none were ever done included the transmission oil change. Better safe then sorry. I do that with every used car I buy.
I have a 2010 IS 250 I bought it at 101,500. I removed the trans pans, drained all the fluid over night. Changed the trans filter inside, cleaned the pan completely. Installed a new Tran gasket. At 101 miles the oil was black. Toyota says don't do it this way because you have to fill the exact amount you take out & most don't count quarts taken out, I do. Now there's no metal shaving in the pan or any old fluid left. I noticed the smooth shits in the first 100 ft driven.
Nice - I may do that when I have the time, but this is my daily driver as of now so I can’t have it down for any amount of time with work. That’s why I introduced new fluid into the system, and used the overfill plug to drain any excess fluid, as per the Toyota and Lexus techs I talked to. So far it works great and shifts smoother. The fluid is still brown, but next time I’ll do the filter, gasket and all new fluid. For now with 170k, the car runs great
Marty you confuse me my man. you strongly disagree with a full flush, then you say you are getting one next time?
G 36 changing all the fluid and filter isn’t a flush. A flush is using special equipment to flush everything through the system via the trans cooler, which lets all the dirt and particles go all over the system, which isn’t the best idea for high mileage cars
Ohh ok my mistake Marty. you taught me something, love your vids tho man
If you put in the exact amount that came out, why do you need to check the level? Or why would there be overflow? I'm about to do this to my 2007 Tundra and I'm just curious when the level needs to messed with when replacing the same amount you took out?
ATF volume expands and contracts with temp changes. Rather than ASSUME the level is correct it is better practice to do a final fluid level check (verification) as Toyota/Lexus recommends. After draining out the old, put in the same amount new plus a half quart. Start the engine slowly shift gears up and down with 3 second pauses to fully distribute ATF through all the nooks and crannies. When temp gets up to (40-45 Celsius) = 104-113 Fahrenheit you should then remove the level check plug and then replace it (with new crush washer = Torque 15 Ft lbs) as soon as the drain slows to a dribble. Then you will be ASSURED you have the correct amount.
Quick question, when removing excess transmission fluid, should the car be leveled prior to removing excess fluid?
I would say yes, you want it level
Do you leave the engine running when you open the overfill plug? Coz I'm thinking, on any trans that have dipstick ,you check the fluid while the engine is running and trans in park at normal operating temperature.
Just 7ndo the top transmission cooler line. Attach a rubber hose. Add 4 quarts of fluid and idle the engine. When clear red fluid comes out of the hose stop. Fill to proper level. Good to go
My 08 is350 has about 80k miles, should I do a drain and fill or wait a bit longer? (How often should you do this to improve longevity/smoothness of shifts)
Any luck?
It drained 2 quarts out the drain level plug… was the transmission too full from the beginning by the previous owner …?
How many quarts are in the transmission at full capacity? One drain/fill seems like you might only be replacing 1/4 to 1/3 of the fluid. I'd want to repeat it!
Some say 8-9 quarts total, so the 3 quarts would only be about a 1/3! Probably could repeat this a few times for sure
This video was amazing 💯
Thanks a million
I have a 2017 IS300 F Sport. I’m not the original owner but the car has 68k miles and I decided to change the transmission fluid. The fluid was dirty and smelled bad. Do u think I damaged my transmission by changing being the oil was that bad??
What’s up bro. Would you recommend adding Lucas Transmission Oil Additive to my 2006 Lexus Is250 Automatic Transmission. It doesn’t shift hard or any super bad problems. I’ve just noticed it sometimes take a while to shift. Like laggy. Or should a simple oil n filter change should be sufficient?
whats the millage to change? just got one with almost 150k dont know if its a good idea . always heard if its below 80k yes but after 100k its better to leave it alone
Recommended every 6 years or 60k miles for transmission fluid. With that many miles you definitely do NOT want to replace ALL the fluid. You may remove all the friction material that keeps it shifting fine. At most a drain and refill, but I'm not sure.
Great video … is have the 2006 is250 AWD I’m wondering if the the only oil by the gear box of front or is it only the aft-ws and the differential in the back 76w85?
Great video n straight to the point, I’m happy you notice some difference in shifting, I’m doing my second drain n fill but using Amsoil this time, nothing wrong with ws Toyota don’t get me wrong, but after seeing some contents and videos on ws Toyota doesn’t hold up as Amsoil signature series, so I decided the switch. Subscribed to your channel 🤟🏼

@@costantineyoussif6679 update?
@@MixDoctaD switched back to WS Toyota and did 2 drain n fill very happy with the result, reason that I switch back because I tried Amsoil engine oil and didn’t get a good result and my car start smoking and my cabin was smelling oil all over so I decided to switch to WS Toyota and decided to return everything I received from Amsoil 👍🏼 hope this help
I understand that the amount of “excess” fluid that comes out at operating temperature will be too much and will leave the transmission low on fluid, causing damage to the transmission. At least for their newer 6 and 8 speed transmissions. For operating temp excess removal there is a longer straw that has to be used to drain correct amount. So crazy. Even Lexus service shops won’t run the procedure.
Never had issues doing a drain/replace with that many miles? I am getting one with 80k miles and was thinking of just going ahead and doing it now as preventive maintenance.
Still working great at 183k!
I love you license plate 😂

My Is250 is at 190,000 miles..I bought the car at 145,000 miles..it’s been rock solid.. my question is for anyone who can answer..do you guys recommend a drain and fill at this mileage..I can’t find records of the tranny being serviced..and as of now, the tranny shifts like butter..any advice would be appreciated..I plan on taking it to the dealer this upcoming weekend..they quoted me $350 for the service..I’m very nervous
How did it come out? Still running good?
Jordan Swadberg still going strong at 205,000 miles..servo motor is going out on passenger side..will cost over 1,000 dollars..but everything else is fine
Jordan Swadberg sorry I just read you’re question..did a drain a fill in October of last year..feels just fine..was very dirty but the technicians said the fluid did not smell burned. It was a good service, can’t really feel a difference when driving . Tranny only feels weird in cold morning drives..it revs higher but most IS250/is350’s do that. Still rock solid under the hood but I have feeling the electronics will soon be having issues but only time will tell.
Thanks! How much did you drain and fill?
Jordan Swadberg Sorry I forgot to mention they had to drop the pan so, I believe it was more than a drain and fill..hope this info helps you.
I have an 07 lexus with about the same miles. Think of doing the same. Hiws the car running now?
Nice! I sold it in July with 184k miles and it was going strong
Do you know if this process is relatively the same for the Lexus ISF? Considering doing this on my car ... car shifts fine just wanna make sure I’m keeping the car as fresh as possible
I believe so. I think it just takes more fluid being a bigger/more gear trans
Be aware, different vehicles can vary widely between the check/overflow temperature range.
For example, my car states the ATF needs to be between 104-113 degrees Fahrenheit,
HOWEVER, my girlfriends car says the ATF needs to be between 185-203 degrees Fahrenheit!!!
Also, my operating temperature in my car is easily 50 degrees hotter than the maximum range.
Just food for thought.
its the same procedure with isf?, thanks
If you do the under glow , just put one strip under your front bumper and rear , all white neons , it won’t be ricey as long as it’s not changing colors lmfaoo
Why you did not change transmission filter?
Does the car have to be cold when draining the fluid ?
Awesome! But is replacing it with synthetic a bad choice? And do you not recommend any oil stabilizer?
I would just use the same type fluid it was originally filled with to be safe, but you could ask a Toyota tech (or two) if adding synth would be compatible with the fluid that remains in the tranny.
Is the car still running while u were draining the over flow? Awesome channel btw!
Yup! Trans needs to get up to temp before using the overfill plug
I was thinking the same thing, but duh. Nothing in the transmition is moving in neutral so it wont be a problem, unlike an engine oil change!
No underglow lol
2 fast 2 furious

You guys are so fucked
@@Highlander1432 how come lol
So you remove the overfill plug while the engine is running ?
You should always remove the fill plug first. I would have filled and drained a few times until the fluid was cleaner.
Yup things I learned this time around lol. Definitely plan to do that
Also check at the start that you can unscrew the overfill plug, if it's stuck you could have overfilled and have no way to get it back down to the correct level.
Shouldnt you replace the filter as well? Is it too much work or we can skip it?
You can do that, and I did on my newer IS350. But didn't seem to make much of a difference, really.
So draining the overflow with engine running??
What temperature does the transmission need to be ?
Great video! I just have a question. i have the exact same vehicle 168k miles, and i am unsure about any prior Trans fluid changes. I recently found a slow leak from the fluid pan gasket and i am curious if i can do this same thing but change the gasket at the same time? thx
Yes change the filter
For drain, fill and overfill plugs are they all the same crush washers?

I have to do this to my 350 if I brake hard I get a pretty good cluck from the trans down shifting. I think I will do the filter also just to be safe because if that fluid is that dark the filter has to be in bad shape.
I’m sure the filter is dirty too, I just didn’t have much time and this was better than nothing. Filter should definitely help!
Changing it now might give more problems. If you do change it make sure you don't flush.
When you felt the clunk was it under hard braking? Because my trans down shifts pretty slow under hard braking. Just wondering if that is what you had going on and the new fiuld fixed it.
WILLIAM LAST
My 06 does that
Not sure wtf?
I thought it may b the cats?!
Puff sounds when downshifting
That means it may be too late Lexus will change it when the transmission starts acting up but not before.
How do you know when the transmission is at the right temperature to open up the overfill drain?
Steven Sevek once it gets to operating temp. The exact numbers you can find on google. Just run it from 3-5 minutes
Digital thermometer take plug barely out measure the drips after 6 to 10 mins idle your at proper temp.
My Lexus has 223 miles on it and shifts rough! Should I do a flush n fill?
Yes
How’s it running 2 years later?
You can do it cold. Just measure and replace the same amount
True! Did that on my ISF later
What operating temp did you do the overfill plug at? In another video they said it has to be between 105 and 120 degrees farenheight only.
Also got VSC after cleaning wires contacts of spark plugs and sensors with rubber seal protection. Got Check engine lite, and misfire cylinder 2. And port injector error. P1277 P0302 After I've discovered that one of three wires from the camshaft position sensor has lost contact. It was only punched to the connector. And I've interrupted the contact when did the procedure. If the camshaft sensor was sending incorrect signal to the computer. Then the computer doesn't send a spark to coil. Today ive got a new connector. Replaced it. Clean codes. So far no check engine. Be careful, if you are not the original owner. Someone before you possibly did a goofy job.
Hm interesting! I have had the car for almost 2 years now...but I recently did spark plugs myself with no issues or check engine light. My Toyota software tells me the VSC is due to my right front ABS sensor. So just gotta replace that soon!
overplug had used after then your car had got "work teperature"?
Hey Marty, (or anyone else who knows or has advice) do you have any personal tips for me? I have a 2006 Lexus is250 awd and it isn’t grinding or jerking at all, but it is shifting rough mostly almost in all gears not too bad but enough for me to take action on it, I’m thinking about going to do a drain and fill to see if that helps and/or fixes but it has shifted fine before, but the trans was never serviced for a change or flush and I’m at 163,000 miles so I reckon new fluid would be good, I’m just worried my trans is damaged but like I said it isn’t as bad as others I have heard of, I just want to know what anyone thinks, I have seen many Toyota/Lexus vehicle with unchanged fluid at 100k-200k miles with no change once and people changed fluid and it fixed it and made it feel better than ever, I know of the it will damage a transmission thing but idk if its a myth with Toyota/Lexus. I know this is long and someone may not read this but if someone does any help would be appreciated
I have the same Lexus and thinking of doing it.
Have you done anything so far?
Just do a drain and fill. Should be between 2-3 quarts unless you drop the pan, than it will probably be 6-7 quarts. I can report after having my transmission serviced that the car is way smoother and faster believe it or not. Just make sure the tech examines the fluid for metal shavings or burnt fluid which has a very distinctive smell. My tech said my fluid was so dirty, I shouldn’t have it serviced anymore. I don’t know what to say about that but, if you’re tranny is shifting rough, have it serviced before it gets worse. Usually when you’re tranny starts having issues, it’s pretty much toast, but that’s not always the case. Good luck to you, and I hope you’re car lasts another 200,000 miles. 🤞

Definitely!
My 2015 IS 250 has 69k miles should I just leave it for now?
Marty Motoring when doing the over flow portion, how would you check the trans temp w/out a scan tool/cpu (to know when to open the drain bolt)?
would it be simpler to capture the old fluid and fill the transmission with the exact same amount that was taken out? With that simpler method, you won't have to worry about jacking up all four corners to keep the car perfectly flat.
That is easier and how I did it for my ISF now. But not the “proper way” but works great
The only way that works is if the car has sat overnight or long enough to where the Trans is the same temp as ambient (as the jug of new fluid is) because Trans fluid expands at different temps.
Was the engine running while you drained the overflow plug?
Yes, the trans needs to get up to temp and the car has to be on for it to work properly
