Transmission shifts very hard from first gear to second gear when in motion. It also has a violent shudder when it is trying to select a different gear, most apparent around 35mph. If brake isn't pressed hard enough, shifting out of park could cause vehicle to run into something due to the hard shift when stationary.

While the truck is in motion and when accelerating around 15-20 mph the transmission will sometimes "hunt" for a gear causing the truck to not accelerate. This results in a mild jerking of the truck when it is trying to accelerate and feels like the transmission is slipping/skipping. This is more apparent when going up a grade versus on a flat surface. So i have to push harder on the gas pedal waiting for the truck…

Extremely hard shifting on lower gears. When slowing when it goes from 2nd to 1st it feels like i got rear-ended. Not all the time but once a day at least. It also shudders when slowly accelerating in traffic, sometimes the rpm goes way high and it lurches forward when it upshifts.

Daily the transmission has a hard shift from 1st to 2nd gear. Potentially causing me to loose control of the vehicle. Ive had it in the gmc shop 3 times and gmc is unable to fix the problem. After the vehicle sits for periods of 4 hrs or more the problem reoccurs. This is a serious political saftey hazard in the 8speed transmission and needs to be recalled and fixed with a new transmission.
