- This video will show you how to service your 4L80E or 4L85E Transmission by replacing the filter, fluid, and pan gasket.
These transmissions are found on a number of vehicles manufactured between 1991 and present day, including the Chevrolet Express/GMC Savannah, Chevrolet Suburban 2500, Silverado/Sierra, and many others.

You DIDN'T flush the fluid from the torque converter. And you NEVER mentioned or said ANYTHING about the fluid in the torque converter and how it will INSTANTLY contaminate the new fluid. You also showed "bad" fluid on the dip stick after changing the fluid and driving the vehicle, BUT you never indicated that it was contaminated fluid.
Hey. Thank you for your commenting, I sincerely appreciate it. The overall intent of this video was to show how to change the filter, fluid, and pan gasket and not a complete service. There are many applications by which it is a better result to just do this service versus completing a full service with a machine etc. In the future, I will be sure to create more content surrounding those protocols. For now, we show videos and create videos with what we think would be helpful to those who are servicing at home with limited tooling. As opposed to fully educational videos in the shop on the lift with machines that cost thousands of dollars that would not benefit a majority of the folks trying to service at home. Happy Motoring, thank you for adding clarity I will pin your comment to the top
@@Revitauto Generally, I'm never hostile to sources of information teaching me something new. The "youtube" situation that more than anything else "lit my fire" was my search for how to "flush" the fluid from a 4L60/80E without having "to take it to a shop." Your presentation was the FIRST one to pop-up in all the youtube presentations. You did a good job of showing how to/what to do with what you did. Might I suggest you clarify, in this video, what you "didn't do," as well as all the other good work "you did do?" Please continue the good work.
How would you go about draining the torque converter? This was a fluid change not a fluid flush, which is a completely different service
It seems your use of the term "contaminated fluid" is misleading, as the fluid is actually upgraded, or less contaminated, not more contaminated, by the process. The fluid prior to changing is used, but working.
On my 2004 GM 2500, when I remove the plug in the transmission pan, about 4.7 quarts of ATF runs out. The total ATF capacity is 13.6 quarts, per one spec I found. So, when I replace the 4.7 quarts of used ATF with new, the total ATF has then gone from 100% old to about 35% new.
The fluid was dark and burnt smelling when I bought the vehicle, but after doing this procedure every 5000 miles (directly after road trips to "mix it up"), 5 times, the ATF seems now seems pretty clean, and I work it hard pulling big trailers.
The cost: About $22 per "swap" (Valvoline Full Syn, Dextron VI spec), times 5 = $110. And I burn the old fluid in my forge and foundry furnace. A pretty cheap upgrade to my way of thinking.
Cns30 is wrong. I do a gallon swap all the time using my vacuum process I have a video on. There is nothing about ‘contaminating’ the fluid. Doing a gallon swap over the many years on my 04 suburban has got it to 279K miles. Don’t listen to his negative comments
AN excellent video giving me confidence for my adventure.
Thank you! We hope you have *many* wonderful adventures

How much oil,needs to add in transportation
What is the correct fluit for tje 4l80e????
I Gotta say I respect a man that provides help on costly repairs that a mechanically inclined person can use.
I respect more a man that leaves the mistake in the video for future help.
MUCH APPRECIATED SUBSCRIPTION DONE. Do you have a diagnostic type or even replacement of solenoid video for this Transmission? I fear my solenoids burnt after a line blew and really appreciate any help
Oh 2001 Silverado 2500hd 4x4 6.0 4l80e
Thank you for the kind words, I do not unfortunately have a video on how to replace or check the valve body. I will say that if you had a failure to a transmission line and the trans was operated without fluid the most likely result is a damaged or burned clutch, not likely for it to be a failed valve body.
What is the level of the trans fluid while on a level surface and the engine running? Does it smell burnt or look dirty? Happy Motoring, Blair
@@Revitauto on warmed engine in park it's reading high after repair which I thought maybe metal
@@Revitauto I pulled over but might have to late it was smoking a short bit when I stopped I didn't drive after with no fluid it was towed but I am prepping for plowing wanted some reputable views and video helped Understand
@@VisionizeTech Gotcha, if you are prepping for snow season I would do some google searches for the highest rated transmission shop to take a look at it. I am not excited about being behind getting my trucks ready!
Thanks for your help

How did you remove the shift cable bracket?

how much fluid did you have to add? Chevy owners manual provides the total capacity for the transmission (13.5 quarts), but does not say approximately how much to add to fill after pan gasket/filter replacement. The torque converter will still be holding a lot of fluid after pan removal.
Usually around 4 to 5 quarts if you're only changing the filter.
I measure the fluid that runs out, then just add that much back. About 150 ounces on my 2004 GM 2500 (has a drain plug in pan).
Any tips putting the pan back on with the gasket ? Keep hitting the shield and then having to fix gasket.
Use an adhesive made for gaskets. put the adhesive on the pan, line up the holes, then put a weight to hold the gasket flat until adhesive is holding. If necessary, tie strings thru some holes on the trouble side. Start a couple of bolts in the opposite side, loose, then take out the string.
Thanks

I have a question about a 2008 Chevy Express van does the transmission have a drain tube question mark and how much does a 6.0 l transmission how much fluid do you put in it?
Hey Tim, can you share your VIN? I will look up the specs on that unit. Typically they will have a drain plug or you have to do it the messier way! You could also try sucking some fluid out of the transmission dip stick fill tube! I hope this helps. Happy Motoring-Blair
How many miles were on this transmission? Was it slipping?
About 130k miles. It was not shifting smoothly, after service it returned to normal operation. Happy Motoring- Blair
I was looking for info on a complete fluid change, it should take about 13 quarts, do you have a video or do you know how to do this
Did you figure it out? Im in the same boat now lol
how many quarts of fluid
Hey Jose! I am not sure! I think we started with 5 checked and filled as needed but dont quote!
Ok so I know I can do this job no problem
Awesome! Let us know how it went for you! Happy Motoring, Blair
Check engine light on?
This vehicle had a couple of non transmission related issues. There were no codes produced from this service. What issues are you experiencing?
My drain plug is stripped 15mm is a bit too big and 14mm too small.
Ouf! I am sorry man, they make great sockets www.amazon.com/Eapele-Impact-Removal-Extractor-Socket/dp/B07X5VGX69/ref=sr_1_2_sspa?keywords=stripped+bolt+extractor&qid=1670792323&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExSzNGMVhRWERERUJDJmVuY3J5cHRlZElkPUEwODc2MzU3MktBM01KM0FSQktNTyZlbmNyeXB0ZWRBZElkPUExMDQ3MjQ4OU1LQTlSUTRVMVIxJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==
Surprised your pan didn’t have a drain plug, mine does
How much oil did u put?
What is the exact type of automatic transmission fluid used in a 1999 suburban diesel?
Hey Thomas, I always recommend using a oem fluid from the dealer or calling your auto parts store and asking for what is the most current recommended fluid is. Happy Motoring, fyi we use Burn Rubber Brewing brand transmission fluid.
Previously, it was Dexron II, & III. However, GM uses Dexron VI now, which you can/should use. I believe you have a 4L80-E transmission: 4 - 6 quarts (dropping pan, & filter ONLY), or 13.5 quarts (total transmission change/ Flush). Can also use Valvoline dex/merc (Blue bottle), its considerably cheaper than genuine GM fluid. Good luck folks.
This DOES NOT show a proper 4L85E trans filter change!!!
I own an 01 Suburban 2500 8.1 4x4.
The 2 rear trans pan bolts are blocked by the rear cross-member !
Do you have a link to proper removal???
take cross member off
Or use a wrench. That worked for me.
Would a 93 G20 have this transmission ?
Would you ask that question at a parts store ?
@@tarquineous yeah...did that and got different answers. Transguy looked at it yesterday. Got a 4l60e in her.
@@elaineclementsfinn1872 yeah, best to get a part # off older vans. Unless you had it from day 1 you won't know.
6 liter
Is this how much fluid you added after the drain and fill?
@@Revitauto
Of course, 6 liters for a 4l60 transmission, but be careful not to damage the transmission if the oil in it is burnt.
That’s only changing 10% of the oil. The rest is in the torque converter.
How much fluid ,,,,waste of time with this video
Sorry you found this video to be a waste of time. You can measure the fluid yourself with the dipstick. For this specific model we installed around 7 quarts into the pan. Different vehicles and different pan configurations will have different volumes. Good luck out there.
