GMC / Chevrolet V8 ATF Transmission Fluid Flush / Exchange (Suburban, Tahoe, Yukon, Sierra, etc)
HTML-код
- Опубликовано: 2 июл 2024
- In this video we'll show you how to change out all the dirty transmission fluid in a 2010 GM Chevrolet Suburban (as well as other GM V8 vehicles) in the convenience of your garage. This process is called a transmission flush or fluid exchange when done at a full service auto repair shop. These shops have a machine that hooks into the transmission's ATF supply and return lines in the radiator. My setup system mimics their machines by using a portable oil pump that delivers new fluid into the transmission while the transmission torque converter pumps out the old fluid into in a fluid container.
To perform a complete exchange, I'll be using 12 quarts or 3 gallons of new transmission fluid. The 3 gallons should be enough to ensure that all of the dirty oil has been pushed out of the transmission. I use Valvoline's full synthetic ATF available in one gallon containers at Walmart or other retail auto parts vendors.
I'll start by letting the transmission pump out around 3 quarts of old fluid before pumping in the new fluid into the transmission oil pan. This will reduce the amount of new fluid mixing in with the old fluid.

Thank you for taking the time to answer people's questions. Your responses and patience are very helpful.
You bet!
Excellent idea. Two "calibrated" tanks. One fluid pump. You made it ultra-simple. Thanks for the great idea!
Thanks! This is the homemade version of a professional shop atf fluid exchange machine.
Might be the simplest and best video I have seen on RUclips in regards to an ATF exchange. Thank you.
Glad you enjoyed it and thanks for your feedback!
I've been doing this for years but never thought of using a cheap oil pump; its so much cleaner this way. Thank you for the video!
You bet!
This is such a well made instruction video. Top notch editing. Concise, clear. Thanks hardly moving!
You bet!
This is what i'm looking for DIY video, simple procedure but very informative in Auto Transmission Oil Replacement.... thumbs on the video
Thanks!
Another great straight to the point video. Keep up the good work
Thanks!
I bought everything listed and performed this today. Let me say it worked wonderfully and put a smile on my face all day
Wonderful and thanks for sharing!
Didn't do it right. Your supposed to drop the litte "e" clip 5 times and spend an hour looking for it in the bowels of the engine compartment!
I know! Have dropped and lost those stupid clips!
😂
Or like me, never find the clip, go to O’Reilly’s, discover they are out of stock, then finally find some at Advance Auto. This was after watching videos and was warned about the clip. Grrrr!
Bummer!
🤣
I have used this method since 1985. I owned a transmission shop for 30yrs. I warranted most of my jobs for the lifetime the owner had the vehicle. It was a requirement that the owner bring in the vehicle annually or every 20,000 miles to keep the warranty in force. I too used 2, 5gal fryer oil containers marked at 1qt intervals. I never saw the need to buy a machine for this purpose. It really works great! No mess and really quick. No pump needed as my fluid was pumped in thru a adjustable measured automatic bulk pump.
Thanks for sharing your background and experience! The auto manufacturers are making it more and more difficult to service ATF: I.e. no dip stick and side and bottom fill ports. Here's a video where ATF had leaked from the radiator and I had to figure out a easy way to get the right amount back in: ruclips.net/video/gPLw_HycBKU/видео.html
Great video on this. Just did it this weekend. Dropped pan, cleaned it, added a 2nd magnet (as per GM TSB), new filter then put pan back up. Initially filled with 6 quarts of fresh Dex VI. Started it up and with this method at the cooler line fitting, pumped about a gallon of fluid into a milk jug. Repeated this until the fluid was same color as new fluid... about 12 quarts. Got it up to temp and had to add maybe 1/4 to a 1/2 quart of fluid. Great process.
Good for you and thanks for sharing!
So far your videos surpass any of the videos I have viewed, thank You. I have not performed the task, as of yet. I shall be doing it,alas. My comments shall be forthcoming afterwards. Again thanks.
Best of luck!
You are a real genius, really great job and thanks for this video!
Thanks! Glad you liked it!
Great video, I like the pump idea. Gives better control for new fluid.
Thx bro
Thanks!
Thank you so much for sharing this most instructive video. I was able to successfully do this ATF flush, which my mechanic wanted to charge so much. I didn't take any chances, so I replaced one per gallon until the fluid came out clean Red. The older one was really blackened. The GMC SUV had 123K miles, so I don't think previous owner did any changes to the ATF.
Yes...if it came out black then more than likely the fluid has never been changed. Changing at 123K miles you're getting ahead of possible transmission problems that could be related to worn out ATF.
Great video! I'm going to do this when i get back from hunting camp.
Glad it helped!
Listen - I give up. I wrote two comments, and both did not "stick" so I wrote the one I did (the third one, below) and I see it stayed. So let me try again.
You are a very creative and thinking kind of guy. To think to do this this way, is really smart, You start by draining the pan (the 3 quarts) and then the result is all new fluid. And all one needs are those two 5 gal containers, and a cheapo pump. I LOVE this. I immediately ordered the pump and the containers, and have received both. I will be giving this method a whirl very soon. Your kind of applied thinking is not seen often. Most everybody just uses existing tools, no matter how expensive, and they don't think a little bit and come up with a better way. You do. Like the hydraulic pump for the bearing press. I continue to be impressed with your creative, practical ideas....THANKS!
Thanks a lot for your kind post. I try to find inexpensive practical solutions as substitutes for expensive machines. Good luck with the flush!
I looked at quite a few of these videos. Yours is the best and safest. Saved the video and subbed. thanks.
Thanks! Glad it helped!
Thanks this video should have a billon views I need this set up
You bet!
That’s a brilliant idea to make sure that the level is always okay
I’ll try it !!
Thanks! Simple concept isn't it?
@@hardlymovingpro Really much, i'm suprised
I guess the machine that costs a kidney works the same
Yup.
Awesome video. To be honest, I'm surprised at the number of critical comments. Haters just gotta hate. I'll be using this on my Silverado at the next ATF change. Thanks.
Can't please everyone!
Will be trying this Friday night. Will update you on the results
Good luck!
GREAT VID!
Thanks!

That electric pump is awesome, so much easier
Definitely!
I just purchased a used 2008 Mitsubishi Endeavor with 105,000 miles.It has a Automatic Transmission. I noticed it had a shudder around 40 MPH. And getting worse. I watch a few RUclips videos on flushing the whole system. I was getting nervous that I just purchased this truck and now a may need a new transmission.
I ordered 17qts from Mitsubishi. I used Mitsubishi Transmission Fluid. That’s what is recommended. I ordered the pump from amazon. I got 2 white 5 Gallon buckets from Walmart. I got 2 - 10ft clear 3/8 ID hoses and 3/8 couplers from Home Depot.
The color was dark pink. No Burnt smell. But I needed to do this. I found the 2 hoses going from the Transmission to the Radiator. All I did was disconnected 1 hose. I connected 1 clear hose to one side and the other clear hose to the other connection. Now I needed to find the one that was pumping the Transmission fluid out. Once I found this out. I put that hose going to one bucket. So the other hose was getting the pump hooked up and new Transmission fluid going back into the Transmission. This bucket i put in 12 QTS = 3 gallons of Transmission to start with.
I turned the car on the old Transmission fluid was coming out fast I waited for around 2 QTS of the old transmission fluid to come out than I started the Pump on the New Transmission fluid going in and coming out I was moving through each gear. From P to R,N,D staying in each for a minute. And starting over again I did it a few times
Around 3 gallon mark I could see the color was getting lighter on the fluid coming out. Has the new fluid was getting low in the bucket in started to add 1 Qts,2 Qts, 3qts. I just wanted to make sure it was all clean coming out. I turned the car off and turned the pump off. I disconnected all the clear hoses and connected everything back the way it was.
I did add Lubegard 19610 Dr. Tranny Instant Shudder Fixx 2 Ounce to the clean fluid. I drove the car around the shudder is gone. The checked the fluid level it was perfect on the dipstick. It’s all bright pink now.
I called a few Transmission places before I flushed my Transmission. They all told me if my transmission has any shifting issues I will need a new transmission and flushing the whole system out will not work. I’m very Happy I flushed the whole system out. And make sure you use the correct and recommended Transmission fluid. Don’t use anything else.
Good story and thanks for sharing! Had similar situations with customers where trans shops want to sell new transmissions and not event attempt flushing. Depending on how bad the shudder is, a flush sometimes works ...sometimes it won't; but at least worth a try.
Excellent ….thanks
Welcome!
Forget the pump, you only need one graduated 5-gallon tank. Since the new ATF comes in 1-gallon jugs, just have a funnel in the transmission fill tube, and simply pour it in. The best part of that kit, is the adapter that allows the hose to be connected to the radiator cooling exchanger. The clear vinyl tubes are also nice, so you can really see the color of the fluid on its way out. The lower the transmission level is, the more thorough the exchange. I've seen some videos, where they drain the transmission until they see bubbles in the line, shut it off, add the gallon, then repeat. I don't think you can damage an unloaded transmission by allowing the fluid in the pan to run out, for such a short period of time.
After a flush, did you notice any difference in the feel of the shifts? I also recommend dropping the pan, and replacing the pickup screen.
I use to do it your way but very time consuming. You can run till no fluid runs out with some transmissions but not recommended. Transmission smoothness is usually noticed with some vehicles.
Genius !!
Simple procedure isn't it?
I do something similar at my shop, however my "pump" is a pump garden sprayer with a valve stem in the side to use shop air. I thought about buying a fluid exchanger for the stupid side fill transmissions, but the garden sprayer was my work around. I just drilled a hole in the side and pulled a valve stem through it. I cut the head off of the wand and clamped a hose to it. At 10-15 psi it will pump about a gallon of ATF or Rear End fluid in about 5 minutes.
Thanks for sharing! Good to know that they're people out there like you who think outside the box!
Checkout this video on my portable wheel bearing replacement solution: ruclips.net/video/1YXzlwpAbdQ/видео.html
I was wondering wafted watching all these flush videos, why not have the return tub in a bucket of new Trans fluid, run the car until it’s fully clear and you don’t have to worry about running it dry. Great video
There's no suction in the return line. Fluid must be pushed.
@@hardlymovingpro I meant with your pump you were using. Sorry I didn’t write “with the pump”. My bad
Amazing
Thanks.
You are a Genius jejeje
Thanks!
I like your system, works well. Keep in mind later model trans have a coarse filter, not ever meant to be serviced. And with no dipstick, you have to search for the plug access location. A fluid flush would help extend their life by refreshing the trans oil.
Older vehicles with dipsticks mostly use a much finer replaceable filter. Should be swapped out every 30t miles, or 50k. That black sludge that collects on magnet also clogs up the filter over time.
Signs of a blocked filter would be whining trans when heavy on acceleration and sitting in neutral. Will end up burning the fluid if driven lots whining thus it becomes lower on lubrication quality and in time taking out your trans. By fully servicing this filter you are able to avoid expensive repairs and keep your older trans shifting nicely. 🤗
Good points.
GM has replaced that filter with an updated one. As well as newer fluid. And the fill hole is on the passenger side. Just above the pan...You have to remove that heat shield to gain access to it. On some you can loosen the rear cross member to get the pan off. Some prying on the exhaust maybe required. The deep pans. You have to drop the exhaust. As it's not coming out..
Awesome idea! I’m planning drain and fill only from whatever comes out of pan drop on 07 Escalade. Do you think it will be ok to use the Red Valvoline Jug Dexron 6 compatible to mix with whatever is left in the system(OEM fluid) ? Thanks for all you do!
My preference is the Valvoline synthetic or Castrol synthetic ATF available at walmart in 1 gallon containers. They're all backward compatible with Dextron VI
Awesome video! One question I want to do a flush/fluid exchange but at the same time I want bring down the pan and replace the filter. After draining the 2 gals, would the pan be slightly empty in order to remove it easier? My pan has no drain plug, that's why I ask. I have 05' Chevy Tahoe with 200k miles.
Thanks! You'd have to check the specs on your car to determine the total fluid capacity of your transmission.
what about cleaning the pan and changing the filter? I've seen one guy pump 2.5 gallons then fill 2.5 then run it till it was clear seemed to minimize blending, great video
Most transmission experts I've talked to don't bother changing the filter. The drain, fill and pump can work.
thanks; why not add fluid through return line with the transfer pump or even gravity feed with funnel? If the pump pick up is down in the the pan and the dipstick tube is as well, would feeding the return line help flow old fluid out of all the valve body passageways?
The transfer pump doesn't have the pressure to pump via the return line. Gravity feed with funnel works but you have to keep an eye on the progress of the funnel oil level, constantly adding more oil (while holding the 4 qt container) and watching the dirty oil getting pushed out when the engine is running. A lot of stuff to be monitoring! You can stop the engine while waiting for the new oil to catch up to the dirty oil that's been pumped out; however, when you stop the engine, you're allowing the new oil to starting mixing with the old oil.
One question, don't you need to shift through the gears so the valve body gets clean fluid as well?
You can if want but won't make that much of a difference. There's not that much oil in the valve body.
love your video
Thanks!
Quick question: Fluid only flows from the radiator side, right? I don't have to plug the disconnected line or worry about fluid flowing out there? Just double-checking. Thanks!
That is correct.
Loved the simplicity of the approach. Am having trouble locating a #86 adapter though. Is there another name for that lil dohickey ?
Disregard the question... found you already answered it. Thank you!
You bet!
Great video, I was wondering what would be the difference if instead of going to the dipstick to refill, why not hookup to the return line of the trans cooler? Does that make a difference or no? I'm currently doing this job on a 1999 gmc suburban 5.7L, 4L80-E
That might work. Never tried it. Let us know how it works out. Wonder if the pump can produce the pressure to push the new fluid back into the trans.
wowzers, nicely done.... question why not connect the new ATF feed line to the line that you pulled out of the rad?
Thanks! The pipe inserted into the radiator which was used to connect to the the rubber hose is just for ATF servicing.
what if i wanted to drop the transmission pan and change my transmission fiter first? would i go abot it the same way or try filling the pan through the dipstick , before i run the engine and pump out the old stuff?
You can do that. Timing consuming.
Not bad, ideally best to cycle Trans through gears PND2L etc, whilst running. Obviously need chassis stands.
Thanks! Use to cycle through gears ... didn't make any difference.
@@hardlymovingpro How do you measure the difference ? The idea is to move oil through all the passages of the valve body and remove as much old oil or sludge as possible. If you just leave in P it won't clean out as well, with a pro flushing machine you actually run it in each gear for a minute.
Awesome video. You coooould just pour in with funnel also if didnt have pump.
Yes you can via the dip stick tube. But it'll take some coordination between filling and draining.
@@hardlymovingpro thanks
Hey there. Great video! Great idea pumping into dipstick while pumping fluid out same time.
I"m wondering if you just hook up another hose to the return line and into new trans fluid if the trans pump would suck up the new fluid too while pumping out the old. (instead of putting new fluid into the dip stick tube) I've been wondering about this and if it would work similar to what you are doing with the oil pump.
Does this make sense?
Also, maybe I missed something? Do you have the stock thermostat on your transmission? I thought it only sends fluid to the cooler if fluid temp hits 190 degrees?
Please clarify this for me.
Never tried attaching the pump to the return time since I don't think the pump has the pressure and I'd have to make adapters to connect the pump line to the return line. With respect to the thermostat, ATF starts moving regardless of fluid temperature.
Dont you have to run thru all the gears while doing this? Just to capture the fluid in thr torque converter
Some people do but nominal benefit IMHO.
Genius
Thanks!
Excellent Idea !!
Glad you like it!
Somewhat complicated, but it works.
Thanks for sharing!
Well done and thanks for posting this video. I don't think there's any way easier and cleaner than the way you showed this done.
Just wondering how long it actually took that pump from start to end of the fill. Also, how many uses have you got out of that pump. I checked the links you provided for the pump and adapters so I can do the same on my truck. That pump had good and bad reviews.
Thanks! I'd estimate the pump is pushing the oil out at around 70% the rate of the torque converter...which is why you may want to stop the engine to let the pump catchup. To date the pump has not failed me. I'd say I used it around a dozen times; mostly on cars with no dip stick and has a transmission with a side fill port. With respect to the pump, you'll have to go to a hardware store to pickup clear tubing and perhaps some hose clamps to keep the hose from coming off.
That number 86 adapter? Is that a air line adapter because it doesn't look the same as what's in the description link? Just trying to see exactly what that is.
Can't advise.
An tips on the pump mine blew in the first 5quarts
All these pumps are made in China. Go to Amazon and get one with the most positive reviews. That's all I can recommend.
Hey sir cuestion do u ever have to swap brakes from camaro ss to a v6 camaro so there is a sensor on the camaro v6 that goes directly tk the caliper and the SS doesn’t have anything to conect them will be a problem if just don’t conect the sensor and leave it hanging there or that will mess with something with the car also the lights cane on is like a P in a circle that turns on any help will be great thanks
Never did what you're trying to do. Can say those sensors are probably brake pad wear indicators. A nice to have but not necessary for the brakes to work.
What size hose and the black hose piece to connect tot he adapter did you use?
Buy the adapter first and go to your local auto retailer and have them size the correct hose and cut you the right length.
When's the best time to drop pan and replace filter - before or after the fluid exchange?
Before if that's what you want to do. I believe there's no benefit in doing so.
If I’m going to flush transmission fluid I would change the filter also does it make any sense to leave a dirty filter in there
Up to you but we didn't at the dealership. Replacing the filter can be a big hassle with marginal return on effort. Something like 18 10mm bolts, cleaning up the gasket residue, may have to remove other parts in the way of the pan to get the pan off. And I assume you're going to doing this without a lift working under the car?
@@hardlymovingpro - car nut doesn’t understand that the transmission filters are not like your traditional oil filters their screens they don’t get super dirty and they don’t need changing every time you change the fluid like most everyone seems to think.
With the oil pan off of my '20 chevy 2500 hd can I just take off the filter and stick a hose in it's place and suck oil out of the one gallon Amsoil jug, then crank it up and let the oil flow out from where the oil pan was into a bucket. Then after clean oil starts appearing in the bucket shut it off, install filter and pan and top off. Thanks.
Thanks for sharing! That's another way of doing it. More time consuming and messy IMHO.
Where did you get transmission adapter from the one that you connected rubber hose to?
Link to the adapter in the text description of this video.
Just found this video and thinking of tackling the job myself. You link (2) different transmission adapters, do I need both for this job? I have a ‘14 Sierra.
Only 1. They both perform the same task. Provided 2 links in case one's out of stock.
@@hardlymovingpro thanks!! What side diameter hose you using to connect to that? Was there any other fitting needed for the connection cause the one in the video vs the ones you linked were a little different looking.
After getting the adapter, you can go to your local auto parts store to get the right diameter hose that fits.
I bought that fluid pump and I’m just curious should I clean it at all first or is it good to use brand new out of the box
Good to go out of the box.
Grate video my friend. I've got one question if I may, can I use a funel and pore the fluid manual insted of pumping it with a pump? Thanks
Yes you can. Slower process.
Hi awesome video ? where can I purchase that fluid pump you’re using thanks the brand name and model number would work perfect for me so I can do research on it
Thanks! I provided links in this video's text description of the tools and equipment used in the video.
For a 2016, it looks like my transmission cooler line is a little bit lower. The line you disconnect is my oil line
Unfortunately manufacture's design keep changing.
Yes on the 15-20 model years the line you need to disconnect is in the driver side. I pumped out my old fluid until it makes air bubbles. I lowered the pan, cleaned it changed the filter. Put bout 8 qts back in then started the car and pumped it until cherry red. I then topped off what was needed. Get up to operating temp and check again. Well worth the effort. I used AMSOIL arc signature. Smooth shifting. No issues. 25k on that fluid and it looks like new
I removed the pan in my chevy express van and changed the filter and poured new oil through the dip stick. There was a lot of metallic shavings from the dark black transmission fluid we removed. Now the car wont accelerate correctly and has issues from moving Reverse or to Drive. Should I try this method and do a second flush? Also, should i buy those transmission flush chemicals to flush out the transmission completely before adding any new transmission fluid???
Metallic residue in the oil is a very bad sign. May have to get the tranny rebuilt.
@@hardlymovingpro Yeah I know, It has like 150k-200k miles on that second transmission without a flush, thats why there was so much because it was never changed. You think doing a second flush with a new filter with this method will help dislodge any debris???
I read this online "This is very common when the old oil was already black. The varnish from that blackened oil is all over the discs, valves, and casings. The new fluid cleans it off and clogs the filter."
I also read this "Your transmission needs a fluid pressure check to make sure your transmission fluid pump is working with a correct psi pressure of over 100 psi, otherwise the clutch pacts won’t have enough pressure to press those pressure plates together to activate those planetary gears and sun gear. There is a check screw on the side of the valve body for the fluid pressure check. Check your transmission fluid level, park your car on a level ground with the engine running at idle speed, and pull the dipstick out to see if your transmission have enough fluid. Make sure you use the correct transmission fluid."
Why would you not pump fluid back in thru the return line instead of dip stick?
I could but the dip stick tube is more direct.
What if you went to do an oil change, accidentally started draining the transmission oil because it’s right next to the oil filter on the Tahoe, but caught it relatively quickly, then did the actual oil change, then went to check the transmission dipstick to see how much drained out, so that you could put a little back in and the dipstick tubing broke and you don’t know how much transmission fluid is in there and you don’t know if it will leak out? How can I do this without a transmission dipstick so that I know I’m good so that I can breathe on the way to work tomorrow? It’s a Sunday and nothing is open and I have to go to work tomorrow. Thanks!
If you have a transmission that doesn't have the dip stick, you'll have to pump the oil back in via a side fill port plug (if it has one) or through the bottom drain plug that has a plug protruding into the oil pan. Keep pump in oil until fluid comes on of the side port or from the bottom drain plug.
Can you pump-it out from the dip-stick and put the same amount back the same way ?
Yes. You can do that but you won't get the drain tube to the bottom of the oil pan. The filter is in the way. I'd guess less than 3 quarts will come out.
@@hardlymovingpro - actually check out my video where are use a vacuum pump to pump mine out I almost always get about a gallon- just shy. It’s a very quick process super easy I put a gallon in every 20,000 miles or so
Have you tried your method on other vehicles? Have you tried it on a Ram 1500? I have a 2016 Ram 1500 Sport 4x4. 5.7 hemi. 8HP70 transmission.
Concept is the same. You'll need to know the type of ATF output port design coming out of your radiator and get the appropriate adapters. Could be a rubber hose secured with a spring clamp.
So i open this line same as you and coolant came out truck was to operation temperature
Could be a different designed radiator in your case. Look for other lines going into radiator or in some designs into your ac condenser.
Great video, where did u get the stuff for this kit or did u buy it on ebay as a kit or purchase everything separate? The fitting u put in the upper cooler line on top of raidator does that come in the kit?
Thanks! Links to all the stuff I used in this video is in the video description area.
@@hardlymovingprook the first time u started the engine did u have the oil pan off and a new filter or didnt do that or just started to pump old fluid out right away?
@@jessesyfie7244 no oil pan removal. Just pumped out the old ATF
What is the nipple piece on your adapter? It looks different than the one you linked, the piece you hook the hose to?
That attaches to a quick connect adapter on a transmission flush machine ...which you don't need.
@@hardlymovingpro thank you
You bet!
If I dump the oil out first and put the pan back on, can I still do this the same way with just what little is left in the transmission or do I have to add some oil first and then flush it out again?
Yes ... you can dump first if you don't mind taking off all those small pan bolts and replacing the gasket. Would also be a good time to remove any sediment in the bottom of the pan.
@@hardlymovingpro thank you
Done three Yukon's this way...They have shift issues. GM fix is to use the newer fluid and filter...To fix the problem.
Be aware.. There is no dip stuck tube on these newer ones..I made an adapter to fit in the lower transmission fill hole..
There's another way. Inject the fluid in. Here's the video where I did it: ruclips.net/video/gPLw_HycBKU/видео.html
Are you saying you have shift issues after following this videos instruction?
@@Damian-xc7km I'm saying the Fix is to Buy the newer Fluid. As GM has a bulletin on it. Erratic Shifting, Slow Shifting, etc...
And you let it go too long. You will be buying a new transmission...
And you flush the whole system..Not a Drain and refill. It takes 13 quarts to do right...
Link to the bulletin?
@@elmera9472 You can not put links in this video. Just do a search Yukon erratic shifting fluid update..
Why not connect the pump line to the other side of the cooler line, in side of that line so the fluid is completing a full cycle through torque converter and flushing out all old fluid?
For 3 reasons: 1. Don't believe the pump has the pressure to push the oil. 2. Need to fabricate connectors for the pump line to the return ATF line. 3. In the return ATF line, fluid is going right back to the oil pan slump (which is what I'm refilling with new fluid via the dip stick).
Would this work on a 2016 Chevy Tahoe I have a p0769 code and I want to flush my transmission before someone tells me to just replace 😩 it’s a ppv version and they said it idled so I really don’t think I need a new transmission
Sorry but don't think changing the transmission fluid will fix a shift solenoid that's not working (P0769).
Do you know if this vehicle has the auxiliary trans cooler as well? Will that matter or is the return line the same regardless if theres an auxiliary cooler.. 2009 gmc yukon denali with the 6.2 and auxiliary cooler.. any info is appreciated thanks🙏
Doesn't matter if there's a aux oil cooler
@Hardly Moving Productions ok thanks man appreciate it just wanted to make sure i got the right return line.. the top line goes into the small auxiliary cooler from the radiator appreciate it
I did this today and when i stop it at 3 gallon mark the fluid coming out was still kinda black / dark red. Does that mean i didnt do it right?
Don't worry to much about the color.
So I would connect the out line to the radiator where the fluid comes out from?
Or where it comes out of the hose into the radiator?
The "out line" is at the top of the radiator. The "in line" at the bottom.
Does the electric pump have to match the flow rate of the transmission? How do you tell the flow rate of the transmission pump??
Flow rates won't be the same. Best to do this procedure with a partner to start and stop the car engine while you control the transfer pump.
What about the filter and magnet and all the dirt in the pan
The "dirt" is clutch friction material that's settled. A lot of time and effort involved in removing the pan.
Do you have to be careful not to empty out the oil pan entirely so transmission sucks in air?
Oil pan will not get empty if you do it as shown in the video. Even if you did empty it, replenishing the pan with new oil will push out air pockets.
@@hardlymovingpro Just did 2 cars - I put a 3/8 inside the trans fitting and it went good. On a Mazda I did the same thing, but it scared the hell out of me - on start up, there was a solid thud moving through R and D - I feared the worst. Fortunately, as soon as the air worked out of the system it went back to silky smooth. So all's well that ends well...
I hope you took the pan off to clean it, and change the filter before doing this. If so great job!!! If not well that guys truck is f___d
We never, ever take off the pan and replace the filter at the dealership because ... the customers won't pay for the extra service!
does doing it this way get the old fluid out of the torque converter as well?
Yes.
do you change your filter in the transmission as well?
Not necessary.
Don't you need to drop the pan and change the transmission filter?
Most of the time nope. If the trans is shifting okay and the fluid isn't too dark with metal particles, just change the fluid. On some American pickups, if you drop the pan, you can wipe off the warn off clutch residue that accumulated at the bottom of the pan. Heard stories where people dropped the pan, changed the filter then starting having transmission shifting problems.

Спасибо!
Thanks
Can you tell me where I can purchase the line adapter? I appreciate it.
I provided a product link in the description area of this video.
The number 86 adapter-where do i get that? What brand / model of pump?
I provided a link to the adapter in this video's "show more" text description.
Would be better if you pumped the new fluid into the return line as it lubricates the spinning parts in that transmission; it doesn't dump into the pan as some believe.
You could do that but the return line is pumping oil back into the pan.
@@hardlymovingpro wrong. Your ignorance is astonishing.
Why did you leave a link for two adapters? Will either work?
Either will work. 2 links in case one is out of stock.
Did u pan drop and filter also?
Not at all.
Why can't you hook the pump up to the return line,and flush that as well???
I could but the dip stick tube proves a direct path to the oil pan.
contamination,bro
Great video. I’m changing the fluid in my 2019 Tahoe 5.3 liter LT. You mention a #86 radiator adapter and I am wondering where I can buy one of these? Is that the adapter that would fit a 2019 or is it a different one? Please let me know where I can buy one. Thanks.
A Amazon link to the adapter is provided in this video's description
So you don't replace the transmission filter?
That's completely up to you to decide. In my opinion I feel it doesn't add much value.
