2021 Tahoe transmission problem

[Hondogreif]

I have a 2021 Tahoe Premiere with 15,000 miles and have noticed problems with the transmission. Best way to explain is that it surges when shifting gears especially in lower gears. Almost seems like jerkiness or like it’s not getting gas. I have also noticed that after traveling at interstate speeds it seems to do the same when cruise is on and traveling at Highway speeds. This doesn’t happen all the time but like it’s between gears and not shifting. I took it to dealership and they said they can feel it doing it but computer says all OK. Trying to see if others have had or heard of this.

I’ve noticed stuff like that with my “21 although I only have a fraction of the miles which you have (4,500). I kinda figured it has something to do with the programming on the transmission and how it likes to latch onto the higher gear all the time.

The surging/studdering I tend to notice more when going up hills around town. I haven’t noticed it as much on the highway but I also don’t travel as much on the highway as I used to.

There’s a new recall issued for the fuel pump control module. Which may explain the surging

Sounds like production dates on that recall are Dec 3, 2019 to Mar 4, 2021. Guessing with 15k miles yours would fall under that.

Mine was built in March 2021, but I’m not sure of the exact day.

I just saw the recall on my app. Called dealership and they have ordered it. Hopefully it is the fuel pump.

Curious what that is since these are direct injected and have a mechanical pump on the engine and an electric pump in the tank.

i confirmed with my dealer that mines outside of the build date range. Guess it’s build date is March 19th.

Got it replaced. Ot as bad as before but still prevalent. I recall having the same problem on a Chevy traverse with a 10 speed transmission. If I recall I was able to reset the transmission control module which took care of the problem. Does anyone know if the same thing can be done with the Tahoe?

Mine is outside of date. Taking for recall this week.
