Transmission Issue?

[cjlewis]

Vehicle: 2023 Yukon 6.2L. 91K miles. Regular service.

Yesterday, while pulling away from a traffic light, the transmission seemed to have difficulty deciding which gear to select. It shifted very harshly and abruptly through 1st, 2nd, and 3rd gear. Shortly afterward, I noticed a burning smell.

Since then, the transmission has continued to feel rough when shifting while driving. The severe, clunky shifting hasn't happened again, but the shifts are definitely not as smooth as they were before.

VB or something else?

Guessing on the Internet won’t be very helpful. You will need to have the transmission scanned for any fault codes. Based upon your description, it doesn’t sound good.

It would be good to check fluid level and condition.
