Solid noise from transmission. Transmission needs replaced...

Solid noise from transmission started only in park and neutral. Noise "eeerrrrrr" (sorry, best description I can think of) was only in park/neutral, but now at anytime, any gear. Can be constant, but does come and go. First diagnosis was torque converter, but after replacing noise still there. Next thought was a solenoid, but ruled out. After research and other opinions, discovered ATSG (Automatic Transmission Service Group) are receiving several calls a week on this....basically, worn pressure regulator and at least pump needs to be replaced. They recommend an overhaul or transmission replacement!! I just went over 100K and bought the 2016 new in 2017.

Anybody seeing this? Is GM acknowledging this?

Also, I am going on my SECOND AC compressor...It has had multiple model numbers indicating multiple non-fixed issues. I have never had this many major issues. I will take any thoughts/ideas. Very disappointed in GM.

Needing a rebuild on a 6L80e isn't that uncommon to be honest. There are known issues with torque converter failures and internal clutch issues, it's just a matter of time before they all end up needing some sort of fix. Some make it 50k miles and other 150-200k miles before it acts up. It's a giant toss up on when something can happen with a mass produced product like these.

 

The $4,000 it may take to fix the problem is a lot cheaper than the 30-40k you would have to spend after trade in to get into a new Tahoe that starts at basically $60,000 now.

At app 86K my trans was skipping and bucking.  Stealer did “reprogram engine and transmission control module” and “transmission service using kit# k6600”, and recommended trans service every 30K.  Now at 94K starting to experience shift hesitation issues.  Good Luck.

Mine shuttered at 86000 at low speeds. Paid a dealer to do a flush and filter change with the mobile 1 ATF . They nailed me 600.00 cause it was out of warranty but the shuttering is gone for now. I hope mine is the 200k miles one

      The Peckish Synapse

      If it has a stick I can have fun with it. When my wife first got her Acura years ago I used to tease her about it. I was only interested in muscle cars. They’re gone now. So once a month I drive the Acura. Every once in a while I’ll take it to Redline. But just normal driving on some twisty back roads usually does the trick.

      2010 Avalanche 5.3 not running correctly after engine swap.

      By contrabombarde · Posted

      I went through again with a test light and everything checked out.    I suppose it could be the MAF itself but I've tried 3 different sensors, 2 of which were in running vehicles previously (the one in this truck, and the one in the donor truck), as well as a new one I picked up from NAPA. I would just be surprised if all 3 were bad.   EDIT/UPDATE: I swapped in the MAP sensor that was originally with the 2010 PCM, that made the code for map sensor voltage high Go away, and the map sensor seems to read normal with key on engine off (14psi or so), but it still doesn't run and does the same thing as before.

      No Software Updates - Old Build

      By Atlas · Posted

      In addition to a cell or wifi connection, the infotainment needs to be enabled to download software updates. That's a toggle within the system settings.   But...if the truck was prevented from receiving updates in a past life, missing a bunch of updates may mean it won't go back and download all of those because they're not available or the system is too far out of date.   If a formal recall depends on a software update, the recall for that truck remains in an open status until it's applied. The dealer would need to apply the software update in that instance.   Most updates downloaded and applied via the infotainment aren't recalls/safety recalls, they're enhancements and usability fixes which aren't critical.

      Brake Pad Warning Message

      By Vu1can · Posted

      Recently I've been getting a message, "New Brake Pads Detected. Reset Brake Pad Life?", But I haven't had the pads replaced and the truck only has 28,000 miles. The Brake Pad Life shows Front 64% and Rear 79%. I select NO to resetting the brake pad life and the message goes away but comes back at the nest restart.   I stopped by the dealer and was told that it sounds like a software glitch that would require reprogramming. Even though I have the extended warranty, they tell me that reprogramming is not covered unless a module was actually bad and needed to be replaced. Simply reprogramming is not covered. So, they want $200.00 just to diagnose the problem. If it turns out no bad module, another charge on top of that to do the reprogramming. If the cause was an actual bad module, everything would be covered under the warranty.   Just wondering if anyone else has had this problem. Should this issue be covered under the warranty?   Thanks

      NHT is diesel only, correct.     The GVWRs for NHT on 3/4 ton bring them to the same numbers as many of the 2WD 1 tons.  A crew 4x4 standard 3/4 with NHT is 11,750lbs, a 1 ton same cab/box/4x4 is 12,100lbs.     Hubs and hub bearings are the same for 11.5" and 12" axles.  Housing, diff carrier and ring/pinion are larger for the 12".   All gas use the 11.5" axle, 3/4, 1 ton and 1 ton DRW.
