Reverse Switch | Removal and Installation TRSM0940
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 posi-
tion. 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 Transmis-
sion 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.
