- How to flush the automatic transmission fluid and change the filter in a GMC Sierra, Chevy Silverado, Yukon, Tahoe, Suburban, Escalade. Steps will work with nearly any car or truck with an automatic transmission and a serviceable filter. This service could help with slipping, whining, shuddering or other transmission problems.
On the SUVs you may need to adjust the exhaust to remove the transmission pan. I accomplished this on a Yukon XL with a ratchet strap around the crossmember and exhaust.

Thanks man, this is awesome. I flushed my transmission like a pro today after watching your video. This is gold.
Glad you found it helpful.
I just discovered your U-Tube channel this weekend and watched about 10 of your videos. I liked them all and appreciated the amount of detail you put into explaining things.
I especially enjoyed the tip on flipping over the adjustable wrench seen in the toilet video to change it from standard to metric .LOL
Keep up the good work.
Thank you so much and thanks for checking out my videos.
This is the best video I have seen for this service. Thank you for providing it.
5 star video! Informational and to the point. Will subscribe!
Thank you so much.
Great job best Trans flush I've seen thanks for sharing your expertise in transmission flush
Thank you and thanks for watching.
You are very easy to take instructions from 👍👍👍
Thank you.
Thank you! So easy, this ol truck driver did it!! 😁
Great video and very informative 👍
Thanks doctor
Thanks for watching. Now get under your truck.
Thx man!
Watching the whole video was worth the "German torque" joke. Goodntite
hope it didnt go boom thanks for the good knowledge and time
I was just towing a travel trailer with it today. Still works good.
Thanks for video! 151k miles on 04 cateye and would like to try this.
Don't ever sell that truck! I'm a little over 200K on my '06, the newer ones aren't going to last like the GMT800.
4L60E goes boom! Hahaha 🤣 jusy got my 06 looks like shes getting a "flush" with 171xxx
Thanks for the simple how to, you probably already know this and I don't want to sound like your "Brothers Uncles Cousins Sister-in-Laws husband, but they make a trans cooler line release tool for 9 or 10 dollars so the retainer clip stays in place and doesn't go flying into outer space. Ask me how I know? Harbor Freight, Amazon or most local parts stores have them in stock. Nice Video!!
Thanks for the tip. Not sure about the HF tool but from what I read the official GM tool is mostly useless because of its shape. If you don't have a ton of room it won't work.
@@HouseDoctorRay The GM tool is in my old retired tool box and it is well used. An OLD retired GM Tech Here. :-)
Hey guy; Great vid!!
I have new to me a 1997 GMC 1500 and I'm gonna say it has had at least 1 change/ flush prior as the fluid color is still a degree of mid red.
I see you used full synthetic.
Another one of those /// so in so told So in So not to use /switch / intermingle old fluids with the stuff..
Course no way your getting all old out.
Napa did not sell the old in gallons.
What do you think on adding a bit of Lucas Helper for small Leakes??
Best; Tom
I don't think it will hurt anything and it might fix the leaks.
Instead of sucking the old fluid out you can just run the truck and wait till stops pumping and turn the truck off right away
OK. Now I just want to smack myself. You're right.
You mean, run the truck without putting new fluid in at the same time, until all the old fluid is out?
@@sdfljkasjdsdf5371 you can do it either way. All at once but you gotta be quick or just shut it off then refill and do it again. I’ve done both ways. If I have a helper I’ll do it continuously, they just hand me the fluid.
So I can change my filter and drain the old oil and seal it back, turn it on without adding any new oil till all the old oil comes out turn it off then add all the new oil?
Better to run it with the old filter in it. Let it pump the old fluid out and add new as it goes down.
Then put it in new filter and fill until the level is good and the fluid isn't foamy.
Drive easily and recheck fluid level.
Good video but you don't to bend your bracket back reach on the top of the bracket use a 40mm to loosen bolts of the brackets in then you can drop the pan.
I changed my fluid and filter. Cleaned the pan and magnet. When I put the magnet back in the pan I didn’t make an effort to put it in a specific spot. Is that going to be an issue? If so I can drain it and put the magnet in the factory spot if there is one. It’s a 2016 Tahoe. Thank u in advance for any advice u can give me.
I think it will be fine.
Ha ha, the experts know. I also have a 2002 GMC Sierra pickup with 267,000 miles and I need to do this. I want to do the full flush on the whole thing. It would be nice if the converter had a drain plug like some did over the years.
Mine is still fine. Not sure about the frame though...
“GoodNTight” 😂😂😂
What year is your truck? Mine is a 04 with a deep pan but does have that triangle area in the rear of the pan.
'06. It's a 4L60 tranny.
Hahahaha! The internet bots: "In 300 or 400 miles, my transmission should explode." Hahahahaha! Great video and practical tips. Thank you.
Thanks, I'm still waiting for it to blow up.
I purchased a 1998 Chevy suburban and it has bn previously used fluid.they did not change fluid.
This transmission is over filled at least 5 quarts is you're process gonna work? The same way ? Out with the old
In with the new?
Sure but you should still drop the pan and change the filter when you're done.
You could at first let it run until you see air then start putting new in until it runs clean. Just don't let it run dry too long.
Where can I get the adapter at I don't see the link for the adapter for the transmission
I have a 2009 GMC 2500 Savana van
When watching the video click "...more" or "Show more"
amzn.to/44uyhfM
What is the purpose of the adapter? Im assuming it is a plug and do you remove it when putting the hose back?
The adapter is used to connect the clear hose to the radiator. The upper port of the radiator is the return to the transmission. Dirty fluid gets pumped out as you put fresh fluid in.
So the fluid comes out of the radiator not the disconnected hose?
That's correct and GM has quick disconnect lines that require an adapter.
Just bought a 03' Suburban 1500 with 242k miles on it, I don't have any service history since it was an auction car, it runs and drives but idk should I change the transmission fluid? Any advice?
Right at the end of the video a link will pop up on the upper left of the screen ( 3 cups of fluid).
Watch that and decide for yourself. Mine was just over 200K and never been serviced. I only did occasional light towing in those 200K miles and my fluid wasn't burnt or dirty.
My opinion is changing the the fluid can never make it worse but I'm just some guy on the Internet.
Any GM dealer can pull up all the service records if anything was ever done at a dealership.
Would it be ok to suck fluid out of pan then drop pan change filter then do the flush or does it need to be done in this order?
The flushing gets the old fluid out and it's difficult to get the right amount back in. It's best to drop pan and change filter after so your new filter doesn't get dirty and you can get the proper amount of fluid in the transmission.
@@HouseDoctorRay thank you!
I have a 2016 without a dipstick. Can I refill through the line I disconnect from the radiator?
Yes, but you still need to get the level correct. That would require removing the fill plug.
@1:45 : 🤣😂. That is so true my friend ! 😂😂 I find it hilarious how these “myths” appear, and somehow it becomes taboo. Great video ! Not trying to be the transmission man, just trying to help out some folks.
Kudos !
Thanks. I don't drive that truck much but it's still going as is my 2015 which now has 140K. I think I flushed that one at 115K.
@@HouseDoctorRay That’s great Ray ! Keepin’ them running is certainly the way to go, imho, given the cost of new vehicles now. No reason why they won’t keep you happy, if you’re keeping them happy 😊
Hard to believe I bought that '06 brand new for under $20,000. I don't think I'll ever be able to afford a new truck again.
@@HouseDoctorRay I think it’s awesome that you still have it, and still drive it ! That’s the way it should be. My very first car loan was in 88, for a 1986 Camaro with 14,500 miles on it, for $7995 🤣🤣
I really don’t see the need to keep up with the Jones next door, that’s just another loan for an item that might be the worst investment possible. I’m driving old cars, and don’t get me wrong here, I love new tech, and I love awesome, shiny new cars and trucks, but I’m happy with my mortgage investment. 😎 That’s one of my happy places, lol ! And I absolutely LOVE working on cars, to the point that my mechanics tool collection far out ways my livelihood tool collection (carpentry) ! You just can’t get that kind of wrenching fun on new stuff, they go so many miles before they need parts !
And I’m poor, so I can’t keep with the Jones anyway 🤣
My 03 Tahoe just passed 300k and i know my fluid is dirty . But im a bit afraid if i change it it will start slipping . It does not slip at all now
Right at the end of the video there is a link to a video that discusses this.
Top left thumbnail with the three cups.
I just bought a truck a 1995 Chevy 2500 to be exact and I was driving it one day and all of a sudden my forward gears stop working reverse is still strong but I dropped the pan no metal chunks or shaving no signs of going out at all but I noticed alot of my transmission fluid turned to sludge in my pan could that be the cause of no forward gears
Sure. Your clutches are probably shot. You could try a flush but I doubt it would help.
Well that sucks don't know much about working on a transmission and dang sure ain't got money to have it done but thanks for answering my question
Maybe this will help:

@@gregcunningham2403 grab a few tools and watch more videos
Would this adapter work on a 2016 yukon with the 5.3?
As long as it has an automatic transmission it will fit.
Can I add fluid through the transmission vent hole? I have no dipstick.
There will be a port near the top to add fluid but you'll still need to access the inspection port on the side to make sure the level is correct.
What I am calling the vent has a rubber plug in it on the Rt side of the transmission at the top of the heat shield for the exhaust. Is this the port you are talking about and where is the inspection port located?

How many quarts of trans.oil put in a 2001 Chevy suburban?
Check your owners manual. When you flush it you'll just have to check after you're done. Run it through the gears then check it again.
Where's the link in the descriptions?
Right under the video title click *...more*
You may need to click it twice.
How did the transmission do after the transfusion?
So far, so good. I think the reason the myth exists that transmissions fail after flushing is people do it after they already have problems.
How many miles on the old transmission oil before the flush? And were you adding clean oil as you were pumping out the old oil?
204K on the old fluid. Yes, I was pouring in new fluid while the old was pumping out.
The gears on my 2003 gmc sierra are slippery after doing this, the gears can't connect anymore
Put it in 2wd, jack up rear wheels and chock the front wheels. Start the truck and run the shifter through all of the gears at idle. Recheck your fluid level.
Are you sure the filter was fully inserted and the shifter cable is on? If your fluid is foamy you have to wait until the bubbles dissipate before you try and drive it and get the fluid level right.
Was 200k miles the first transmission chang?
Not yet! Any day now.
WHAT IS THE HOSE SIZE ON THE TRANMISSION FITTING TOOL?
3/8" ID
Where do I get the adapter? Ty
There is a link in the video description.
Where is that at@@peersupportcounselor1904
Where do I hook the adapter to the top line like how it is on the video or the bottom line
Top port of the radiator. That is the return to the transmission.
@@HouseDoctorRay thank you
@HouseDoctorRay how about temperature. Can I do that with cold transmission?
Most of the newer GMs have a transmission thermostat that is supposed to block flow until it warms up. That being said on my 2015 I did it cold and had no problem.
Possibly the thermostat blocks the return flow until it warms up.
@@HouseDoctorRay thanks
How much oil did you need to fill back up??
Don't really remember. I went through about 3 ½ gallons total between the flush and the refill.
11.6 empty from the factory. Think it's something like 7 qts if you only drop the pan.
Has it been 300 miles?
A few thousand and still going strong. I also flushed a 6L80 in my 2015 and it's gone another 25K with no problems.
OOPs! The fluid came out of the line to the transmission, not the top radiator port. What a mess! Run lines from both until you determine which way the fluid flows.
Did it explode?
Haha. Not yet, any day now...
@@HouseDoctorRay lol I'm doing mine tomorrow Happy 4th!
Thanks. Good luck.
Lol he's funny. If the experts are correct in about 3 or 400 miles his truck should explode 😂😂😂😂. Well did it tho? I'm sure it didn't
No, I've only put a few thousand miles on it since then but it still works fine.
Can changing gears during the flush F-up the transmission? That’s what this idiot did… I let a few quarts drain out in a few gears with the e-brake applied. My 2005 Sierra won’t move in drive or reverse now. I also didn’t find that fancy attachment you had to attach the hose to the radiator for the flush. I just had a 3/8 hose to shove into the radiator fitting to do the flush.
This is sketchy and try at your own risk:
Warm it up and check fluid level.
Shut it down chock front wheels.
Put the rear axle on jackstands.
Start it back up.
At idle put it into low gear.
If the wheels start spinning, run it through the other gears at idle.
Make sure to hit the brake before going into reverse or park.
Put into park and check fluid again.
It's possible the filter wasn't inserted fully.
End result was great! I just had to top off the fluid. Someone said the transmission won't engage from park to reverse or drive if fluid level is too low. needed 7 more qts of trans fluid. Truck runs as good as always at 290k miles. I put almost 6k miles on it since the flush. The flush would have gone a lot smoother if I just had the radiator attachment you had, the clear hose & a 5 gallon bucket instead of the oil drain pan I had.(something clean & specifically for that purpose)That way I can clearly know how much fluid came out. For anyone doing this for the 1st time.. all those parts are probably at Lowes. Clear plastic hose for sure & I know I saw the correct 3/8 attachment that may fit the radiator & tube. The 5 gal bucket was a cheap there. My worksite was a ghost town so I took my truck for a spin, cycling through all the gears once I was comfortable with the fluid level. I did that without pressing on the accelator at all.. that way fluid will cycle through the gears of the transm before driving at high speed.
Did your transmission start slipping afterwards? Lol
Not yet. About 5,000 and 15,000 on my two GMCs since I've done it. One is a 4 spd and the other is a 6 spd.
Following up on this
Still running fine.
Can’t get it to play. Bummer
Say it ain't so Terry. Try again. It's the most informative video you'll ever see.
@@HouseDoctorRay tried it yesterday and today. Many times. All other videos will play. I’m going to suck out atf tomorrow and add fresh atf and Lucas additive so I really wanted to watch. Maybe I’ll try to reboot my phone. Thanks doctor
Reboot didn’t work. Bummer
😥
😂German torque 5/5
Torque wrenches are for head bolts and bearing caps. I don't think I've even used one on a crank bolt or pressure plate.
The return line from the radiator is what lubricates the transmission, so you ere doing damage which is not smart. Rethink your strategy.
You are 💯% correct, and people just don't understand this is NOT how to flush an automatic transmission... Running the unit without return fluid going into the lube circuit will cause damage to the bushings in the transmission and do more harm than it's doing good...
If you don't have a true flush machine then just drain and fill.
👍
So if you have 2 people adding the transmission fluid into the vehicle while it's running. One thru the dipstick, and one on the return line. Won't that take care of this concern. Or not. My transmission gage runs hot when I'm towing my trailer, so I'm trying to figure out the easiest way to fix the problem. Any ideas would be much appreciated
If you have a GM there is a thermostat on the side of the transmission where the lines hook up. Like anything else they can go bad.
If you don't already have one you should also add an air cooler after the radiator if you're towing. SureCool is pretty popular mod but I have no experience with it.
Good an tight 😂.,👍
