2021 transmission problem

Dewhite said:

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 ?

I've had my 2021 Yukon since August. no issues

Issues or not, buy a Ford SUV and you'll get the same transmission. This transmission was a joint effort between Ford & GM.
I have a 2021 Yukon and so far no issues.

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!..

So far after one week of ownership had to be taken in to clear an auxiliary fan issue (check engine light), then was in the shop with 4000 miles on it for a complete heater core replacement. Now I’ve been noticing a strange sound after parking it, you can hear something wet hit the hot exhaust, making a sizzling noise. Then today after dismissing the sound drove it down my driveway to have the transmission make a huge racket. Check engine light is on, headed to the shop in the am. It has been shifting rather hard also.
I have a friend with a 2021 Yukon, leaking transmission also shifting hard.
GM has me questioning my loyalty after this expensive buy.

Yes!!!!! Took it in now for the 3rd time because of course first 2 times they told me there was nothing wrong with it!!! It's been awful to drive for 6,000 miles and now I took mechanic for a ride with me and now they believe me...probably new transmission. Completely disgusted

Hey Dewhite, we have been having issues with our 2021 Tahoe since September 2020. It’s been in the shop multiple times. We are getting a lot of jolting when it shifts gears. What happen to yours?

Mine was just making a noise and after I brought it in and complained a lot, they replaced it

What noise was it making and how did you discover it? I only ask bc my 2021
Yukon is making an odd sound as well.

It was making a sound like something was loose, I can’t explain it any better than that, sorry.

I have a n2021 Yukon AT4 and had to have it towed to the dealership yesterday
It was making a loud noise like something was dragging and acting as if I had the parking break on… jump and lagging.
very disheartening when you pay that much for a vehicle. The last Yukon I purchased 2 years ago ( brand new) left me stranded on the side of the road twice. I’m about done

Sorry to hear that, my 21 Tahoe has been in the shop all week, it really is a piece of crap, but well designed. I will it would run, because I really do love tge look and feel of it. But its crap, good luck with yours.

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?

We took are 2021 Yukon Denial into the dealership on Saturday because the transmission clunks and the clutch started slipping. When driving it there the check engine light came on and the truck start running rough didnt think I was going to make it to the dealership. I call the service dept. today and the service manager they told me they start the truck and it sounds like a lifter going out. So here is an update on the truck with 7300 miles on it the it broke several push rods and the damaged the heads. The dealership still hasnt been able to check the transmission at this time.

I have 21 suburban z71 with the same sizzling you mentioned and a rough transmission. Did you find out what the problem was? Is it a necessary fix? I have no servicelights on.
