ACDelco GM Original Equipment 88962315 Transfer Case Range Select Position Sensor

Easy install, works great !

Waaayy cheaper than replacing the whole encoder motor. Most of the time it is only this sensing ring that is gone bad. At a fraction of the cost of a Tcase motor you can replace this part. Took me 45 minutes start to finish. All error codes are gone, the Tcase shifts smoothly, no more grinding from partial shifts position. Get it.

This fits my 2005 Silverado and is located inside the 4WD shift motor. Easy install once the motor is removed and the entire repair took less than an hour. Remove the skid plate, remove the front drive shaft, unbolt and unplug the shift motor. Remove 2 screws to open the shift motor, mark both gears with a marker to ensure proper alignment during re-assembly, unplug and remove encoder ring. Replace with new encoder and put it all back together. No more issues with the transfer case and now it shifts right every time.

The only part that seems to fail in the automatic transfer case encoder motor, way cheaper than the whole unit, but be sure to only buy the AC Delco part, it’s the only one that works

Will work to replace a faulty sensor on a transfer case motor.
