Car does not shift from park to drive Inspection
When a vehicle fails to shift from Park to Drive, the issue typically stems from a breakdown in the shift interlock system—a safety mechanism designed to prevent engagement unless the brake pedal is pressed. The most common culprit is a faulty brake light switch or a blown circuit fuse, which stops the interlock solenoid from receiving the signal to unlock the gear lever. Other potential causes include a failed shift lock actuator, a stretched or broken transmission shift cable, or mechanical binding against the park pawl when parked on steep inclines. A thorough inspection involves verifying brake light activation upon pedal depression, testing battery voltage, testing the manual shift lock override, and inspecting the linkage cable at both the console shifter and transmission range lever for loose or worn bushings.
