crankshaft

A car that won't move when in reverse could indicate a problem with the transmission. It could also indicate a problem in the gear selector.
The purpose of an accelerator is the car is to give the engine gas so the car will move.
Drive...
Not sure of the question, but if your car is less than 7 yrs old, apply the brake first, then you can move the shift selector.
No
The same problem with my Lincoln town car. When disassembled the transmission, it was evident that the reverse piston did not move, "valve body" can not reverse the piston to move. All valves tested by documentation. I can not understand the problem!
transmission is gone.
If the car is facing up a hill, simply put the car in nuetral. :D When placed in "reverse" an extra gear is added to the chain of gears in the transmission which causes the final drive to the wheels to turn in the opposite direction.
