Hello Jeremy here from Kentucky. I have an 02 suburban half ton two wheel drive, that I just had the transmission rebuilt on barely 2 months ago. Everything seemed to be working flawlessly after I got it back, towed trailers, and other cars on dollies with no problem at all. But then yesterday within 5 minutes of leaving my house the transmission with literally no warning acted as if I had thrown it in neutral. I was able to Coast into a parking lot where it currently is still sitting. I checked the linkage it all seems fine, I tried to reset the ECM and TCM however, that changed nothing. I thought about the neutral safety switch, but I had been told that if it were to go bad the truck would start even in gear however that is not the case. It seems the only thing that's working correctly is when I put it in park. I'm kind of stumped if anybody has any clue where I should go from here please please let me know thank you
