GMC K2500 Car does not shift from park to drive Inspection at your home or office.

How a mechanic will inspect a car that won’t shift from park:

There are a number of reasons why a car will not move from park to drive. They can range from the shifter being locked to a broken shifter cable. Mechanics will check for these things:

• Failed brake light switch

• Bad shift interlock solenoid or wiring: The shift interlock solenoid is a safety feature that has been added to all modern automatic-transmission cars. It prevents the driver from shifting out of park without a foot on the brake.

• Broken transmission shift cable: A cable connects the shifter handle to the transmission, and if that is broken, the shifter will be inoperable

• Ignition key tumbler is worn out: The ignition switch not only starts your car, but it also locks the steering wheel when the key is taken out. In cars with automatic transmissions, a shift interlock solenoid is also part of the ignition system, and it locks the transmission so it cannot be shifted out of park (as described above).

• Broken shifter mechanism: It is also possible that the shifter itself is broken. A mechanic will remove the center console to examine the actual shifter mechanism.
