Chevrolet GMC Cadillac Transfer Case Shift Motor TRQ DTA15603

It did not function as needed,

Looked exactly like mine. Installed with no problem. Did not correct my problem. I will continue to use A1 audio for my parts

Part ordered was an exact match and installed easily.

Installed part easily but then vehicle was stuck in 4 wheel drive (high). Could not figure out what was wrong with it so had to take it to a dealership. They said part was faulty and replaced it with an oem part and it worked. Ended up costing me $700 and a bunch of extra hassle. This part did not work fir my truck.

I ordered this part for my 2012 Silverado 1500 with a "service 4wd message" showing on the dash. A scan showed the C0396 code was stored which lead me to chase down wiring, connections, fuses, and finally purchasing a likely failed replacement part. I swapped my oem transfer case motor for this one and was surprised when it worked briefly then got my truck stuck in 4wd. After some work I got it back to 2wd and dropped it off at the dealer as I was at a loss. They did a diagnostic ($200) to tell me this part was bad. Filed a warranty claim with 1a auto where I was told I could only replace the part, so I did. I swapped out the original bad motor with the replacement and once again, it was bad out of the box. The motor was testing with an open ground resulting in a high voltage error back to the tccm. I ended up purchasing a Dorman locally and it works perfectly. Save yourself a headache and avoid this motor! I should have known better when it was 1/2 the price of the Dorman.
