2021 Chevy Tahoe RST 5.3 with 3.5K miles. I have a whine on deceleration and a little whine on acceleration, almost sounds like I have a supercharger. I thought that it might be transmission or something, but dealer says they don't hear anything. Let me know what your dealership says when you take it in. Thanks
2021 transmission problem
Hey Board, I'm new here, Happy New Year to all,
I just got my 21 Tahoe Premier back from the shop after 3 full weeks.
They had to replace the transmission, has anyone else had any issues ?

2021 Chevy Tahoe Premier - 8.5K miles - whining on acceleration at all speeds - dealership took a month to diagnose (they did give us a loaner car, not SUV), and was diagnosed as the transmission pump. Parts were backordered for another 3 weeks, and still don't have it back. 2 months in the shop now.
Yukon XL 6,000 MI... the sizzling sound started about 4 days before the lifter blew. You'll know when it happens because there will be a loud knocking from the engine compartment.
Update... The dealer confirmed it was a broke push rod on cylinder 3. Replaced all lifters on bank 1. The issue I have is bank 2 lifters are still the old ones and could go at any time. They pretty much said yeah that's the case... it could happen tomorrow or never happen again. I said that's not very reassuring and not what I want out of a Yukon XL when I'm traveling with my family.
I have heard some people received an extended warranty due to this issue... Anybody hear about that?

I have had my 2021 Tahoe since September 2020, Its been in the shop multiple times. This time for the transmission. I think its time to get a new vehicle...

I just dropped mine off last Monday at the dealership I hope they don't have it that long. It spent 2 months for the check engine light last year.
After further diag we have ordered the following parts: Transmission Valve Body: 10L80 stator support Valve body & seals, filter, oil pump drive & driven gears, retainer, fluid exhaust gaskets, transfer case gasket. Most of the parts are easily available but one or two we are having a hard time finding, once the part is located I will have a idea on a delivery date. I have checked with Enterprise and as of today there was no vehicle available. We were advised to check back Monday to see if anything would be available. I will be out of the office until Monday and will check in with Enterprise then and get you an update. Have a great weekend.2021 Chevy Tahoe RST 5.3 with 3.5K miles.

My local AAMCO transmission shop says they see 2021s come in every week for new transmissions, out of warranty, $7200. My 2021 Yukon is having the lifter problem and the dealer had it for a month/sent it to a machine shop to drill out a broken spring and something else in there...now it makes a completely different sound/squeak... I'm filing the lemon law claim...Yep..Picked up my new Tahoe High Country last week..Drove it less than 200 miles and it needs a new transmission...The most expensive car I’ve ever had and it’s in the shop after 7 days...Nice job GM!..
Wow, I see a lot of different issues. The issue I am having isn't mentioned. It has this vibration at very distinct speeds., 25-29, 45-49, 59, and more. It is very noticeable when accelerating smoothly, non aggressively. The vibration is so prevalent that it is felt in the seat and throughout the steering wheel. It has been to the shop twice, the last time I took the mechanic with me and he witnessed the vibration at the low speed, we didn't get on the highway at higher speeds. I left it with him for a day, he states its the DFM switching back and forth with cylinder deactivation. Seems odd to me that it does it a those exact speeds and its constant when at those speeds . Anyone else experience this?
I took possession of my 2021 Yukon Denali and have driven it 27,000 miles. Lifter problems started at 26,000, but other than that, it's like riding on a cloud with bells and whistles. Because it keeps having to get sent back to the dealer for those repairs, I'm sending it back.I've had my 2021 Yukon since August. no issues
this is what i had, it was more of a lurching (to me), but i could also describe it/experience it at times as a vibration.shudder. At very distinct speeds. Like 35mph, 55pmh. I took it in and nothing was found, but then I asked to take the technician for a drive, and miraculously, 1 block for the dealership, it did the back nd forth lurching (he shook his head - "that's not right..."). Took them a while to diagnose. It ended up being the transmission valve body.Wow, I see a lot of different issues. The issue I am having isn't mentioned.

Brought my 2021 Z71 Tahoe (built Feb 21) at 34K miles for this EXACT issue. Same speeds, same issue. I’ve taken it up there three times: 1st they couldn’t get it to duplicate and sent me home. 2nd I mentioned the lifter issue and they replaced all 16. Got it back and it runs worse now than before lifter replacement. 3rd they stated the car is fine but the vibration is most def still there. Curious if they replaced the DFM and if this fixed your issue? We’re considering trading in for an Escalade but I’m terrified of the same issues happening and that my trade value will decrease as there is no way any experienced tech can drive this car without noticing the vibration.Wow, I see a lot of different issues.

How long did it take them to diagnose? We purchased a bumper to bumper extended warranty so I’m not too concerned on timing/warranty coverage (I believe it will be) but I just want my car fixed.this is what i had, it was more of a lurching (to me), but i could also describe it/experience it at times as a vibration.shudder.

I just got word that they will be replacing the transmission valve body in my 2021 Tahoe premier. Wondering if that took care of the issue? My problem was more prevalent during summer months and it took 2 summers for them to finally do something.this is what i had, it was more of a lurching (to me), but i could also describe it/experience it at times as a vibration.shudder.

Update: Took it to another dealer, Technician drove it, he felt the vibration. Plus, he own a Suburban of the same year and style, he said his doesn't do that. After about a week of diagnosis, they ordered a torque converter. Back ordered, so no expected date. This vibration gets really annoying, especially when towing. I have been towing a lot (long distances), it is very noticeable. Hope the converter fix it, if not thinking of trading. We will see.

After valve body replacement PROBLEM SOLVED
Whatever came of your car? Mine shut off yesterday, but not before losing breaks while going down a hill, to then have the car slam into park. GM actually replaced the transmission 2 weeks ago due to shifting hard and clunking into gear.Our 2021 Tahoe cut off while driving and would not start back. It is currently sitting at the dealership with no answer as to what happened yet. Sounds similar to your story. Any updates on what was the issues with your vehicle?
