04 transmission in 03 Tahoe problem
Just to make sure before I started taking anything apart, I just unplugged the main harness of the transmission then I'm still able to go forward in one gear. Doesn't shift any. Also has reverse. Seems a little strong to be third but I don't know for sure.- Hempwizard

I've done some checking into where the transmission came from and I know that it was working perfectly when the vehicle it was in was rear ended. It had 103,000 miles on it.
