Reverse Switch

Special Instructions

The Reverse Switch is a normally open ball switch. When the transmission is shifted into Reverse, a ramp on the Reverse Shift Yoke contacts and raises a pin. The pin depresses the ball on the switch, which closes the switch contact, allowing current to flow through the switch and light up the vehicle backup lights.

1. Reverse Switch

2. Gasket

3. Actuating Pin

Reverse Switch Testing

  1. Disconnect the wiring from the switch by lifting the connector locking tab and pulling the connector out of the switch.

  2. Connect an ohm meter to test for continuity.

  3. Place the Transmission Shift Lever in any position except Reverse. If the switch is working properly, the ohm meter should read open or infinity. If it is not, remove the switch and recheck it for continuity. Replace as necessary.

  4. Place the Transmission Shift Lever in the Reverse position. If the switch is working properly, the ohm meter should register continuity or a small reading. If it does not, remove the switch and recheck it for continuity. Replace as necessary. Also, check for the presence of the Reverse Pin.

Reverse Switch Removal

  1. Disconnect the OEM wiring. Remove the Reverse Switch using a 22 mm or 7/8” deep well socket or box end wrench.

  2. Check for the presence of the Reverse Pin in the bore under the switch.

  3. While watching the Reverse Pin, move the Transmission Shifter between the Reverse position and any gear. The pin should raise when the Transmission is shifted to Reverse and lower when the Transmission is in Neutral. If the pin does not raise and lower, inspect it to see if something is causing it to stick, and inspect it for wear. Also, remove the Shift Tower and check for wear on the Reverse Yoke Ramp. This ramp can be seen through the shifter opening.

  4. Remove the pin from the bore with a magnet and check it for excessive wear. If it is worn, replace it.

Reverse Switch Installation

  1. Insert the Reverse Pin in the Reverse Switch bore. (The Reverse Pin is longer than the Neutral Pin.)

  2. Install the gasket on the switch.

  3. Install the Reverse Switch. Torque to 15–20 lb-ft (20–27 N•m).Connect the OEM wiring connector, making sure the locking tab engages properly.
