Q: Car leaking transmission fluid

asked by on

The transmission in my truck will not select gears.

A: Hello. If the shifter will not move at all ...

Hello. If the shifter will not move at all then the shifter interlock may be failing. This system keeps the shifter locked in park until the brake is applied. If the brake switch fails or if the lock solenoid fails then this will occur. If the shifter is moving and just not registering on the transmission then the shifter cable may have broke. I have seen a lot of these brake causing this to occur. Worse case scenario is that it may have a serious internal failure. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to locate any transmission fluid leaks and determine what repairs are needed.
