2025 Yukon Denali 6.2 Transmission

thigaustin · Monday at 10:54 AM

I have been in my Yukon for three weeks now and there is a consistent hesitation / jolt going to second gear. Is anyone else experiencing this?

I will be taking it to the shop after the holidays but already a disappointment to have to give up the car to the shop for an estimated 2+ weeks to figure this out.

I also have the crooked tail pipes that others are reporting... (here is a video of my car right before I picked it up:

)

Hopefully just a simple reprogram. PS - I like that blue colour. What colour is it? Reminds me a bit of the Shoreline Blue Pearl that my 4Runner had.

Its Downpour Metallic.

Does it hesitate while shifting in manual?

It seems to be ok in manual mode, other than the expected delay to shift but that is consistent across the gears. Hopefully this means it is software and not a physical issue!?

It appears that your issue is software related and can be adjusted accordingly.

Sorry, I dont have any experience with the ten-speed units but jolts/rough shifts are usually valve body or electrical/electronics (transmission or engine mgmt).

I really like that color and the interior looks great as well. We have a 22 Yukon and I have no complaints with the transmission. For sure take it to the Dealer while you have your warranty, maybe take it to multiple Dealers (GMC, Chevy, Caddy) just to see if you find one that really knows their stuff and knows how to treat the customer.
