Reverse Inhibit Description and Operation

The reverse inhibit solenoid is a safety feature which prevents an inadvertent shift into reverse at speeds above 5 KPH (3 MPH). The system consist of the following components:

• The powertrain control module (PCM).
• The reverse inhibit solenoid.

With the ignition ON battery voltage is supplied directly to the reverse inhibit solenoid. At forward speeds above 5 KPH (3 MPH) the PCM grounds the control circuit of the reverse inhibit solenoid. This energizes the solenoid and mechanically blocks the shift lever from going into the REVERSE position.
