The correct part and works perfectly. These do need to be programmed no matter where you get them from. 10 out 10 for this product and quality.

It’s the rough part. I have a 2012. Cadillac 3.6. Liter engine S R X. This part is to small. I need heavy part for this car. I need E39. 12648906 G.M part. If you can help me let me know. And thank you.

I had a problem with communication on the J1939 network with the old module. This part was a perfect replacement, installed and programmed, everything has been good so far I wanted to wait a few months to be sure that after installation everything was okay.
