Question about 1996 Chevrolet Suburban
I have the same problem, but when I pull the transmission fuse I can get 3rd manual and reverse only. Also, when I pull the fuse, the pcm is supposed to go into ''limp home mode'' , but it acts like nothings wrong. no check engine light or anything! I took it up a mountain and turned to around, put the fuse back in and when it got up to 3rd gear speed it engaged in 3rd but 1,2, and 4th didn't work. The transmission is recently rebuilt and I just replaced the valve body and tested all the circuits and replaced the pcm. I think the problem lies in why the check engine or check guages light doesn't work as well as the limp home mode. Also the trans would work and go out and work again. like it was a bad connection. I have not found any bad connections. Anyone have a clue. I sure don't.
Ask the rebuilder, maybe a warranty item

Check for loose or broken pins in harness jack or pcm and valve body
