REMOVAL & INSTALLATION
See Figure 1
- Disconnect the negative battery cable for safety.
- Raise and support the rear of the vehicle safely using jackstands. Support the rear, not the front of the vehicle, so the back of the switch is facing upward. This should help minimize the amount of the transmission fluid which might weep from the bore once the switch is removed.
- Position a small drain pan or rag under the switch, just in case the vehicle is not supported at an angle which would prevent transmission fluid leakage when the switch is removed.
- From the left rear of the transmission, disengage the electrical connector from the back-up light switch.
If you are simply replacing the switch, prepare the replacement now (refer to the first installation step) and keep it handy. You can also minimize fluid loss by removing the old switch and immediately threading the new one.
- Loosen the back-up light switch using a suitably sized box wrench or deep socket made for switch removal, then remove the switch from the transmission assembly.
- Apply thread sealing compound and install the switch.
- If a suitable deep socket and torque wrench are available, tighten the switch to 17 ft. lbs. (23 Nm).
- Engage the electrical connector, the connect the negative battery cable.
- Place the gear shift lever in the Reverse position and check the back-up lights are turned On.
On some vehicles the ignition must be in the ON position in order for the reverse lights to work.
