Consumer Description

Gear slipping since I’ve had the truck. Replaced parts of motor, new transmission installed and still gear slipping entering the second gear. A big jolt happens every time I accelerate and when I slow down about the 10 mph mark it jolts again. Spent well over $10,000 on major truck repairs. I just don’t understand how this truck has 0 recalls. My truck is similar to all of the v8 Sierras of that year and I strongly feel it should have been recalled due to the gears slipping and not enough power.
