What Issues Are People Reporting with their Transmission?
When a driver accelerates or decelerates, the cars will reportedly hesitate and then shudder, jerk, clunk or “hard shift” when the automatic transmission switches gears. This may also occur when the vehicles are accelerating in a single gear and not necessarily switching gears.
GM has issued 13 technical service bulletins related to shifting issues alone, but none of the suggested repairs have remedied the problem. Dozens of complaints have been submitted by drivers to the National Highway Traffic Safety Administration over these transmission problems.
