Electrical/Garage Shift Test

Perform this test before a hoist or road test in order to make sure that electronic control inputs are connected and operating. If you do not check the inputs before operating the transmission, you could misdiagnose a simple electrical condition as a major transmission condition.

1. Start the engine.

2. Depress the brake pedal.

3. Move the gear selector to the following positions:

^ Park (P) to Reverse (R)

^ Reverse (R) to Neutral (N) to Drive (D)

^ Gear selections should be immediate and not harsh.
