ACDelco GM Original Equipment 88962315 Transfer Case Range Select Position Sensor

Great fit and seems to be made well installed on 2004 suburban 5.3 fixed my intermittent switch from 2nd to 4 low

Worked like a charm. My 4 x 4 is working again

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.

4WD message constantly came up. The selector switch lights finally stopped lighting up. During research, a 12 year old video showed up in my YouTube algorithm showing me how and why I needed to replace this sensor. So I did, now everything is working perfectly. You can replace it with out dropping the drive shaft, but it so much easier if the drive shaft is out of the way. It takes 5 minutes to drop the drive shaft. Most videos I watched people would change out the whole motor. The sensor tells the computer and the dashboard switch lights what position the drive is in.

Great price for the OEM part. Aftermarket encoder rings were almost twice the price. The 4WD has been out for 12 years (It mostly sat up, didn't drive it much) finally decided to find out what was wrong, and after doing some research and borrowing a proper scan tool, confirmed the issue was the encoder ring. Dropped the encoder motor, took it apart, swapped out the ring, bolted it back on, turned the ignition on and the 2WD light was now on, all modes worked, and the "Service 4WD" message was gone.
