Transmissions & Drivetrains
why do the car shift hard comming out of park to revirse and to drive.
it make a loud thump. what is wrong.
first check the transmission fluid level make sure it is not low. next how many miles on the car? and how do you drive the car? this sounds like an internal tranmission problem. A hard shift can be sticking valves in the transmission or be caused by worn gears or bearings. what was the drivetain warranty on the car usually it is 50,000 and 5 years? so it might still be under warranty
