I recently bought a Tahoe and it has no reverse. All the forward gear are supposed to be fine but I havn't drove it because the guy I bought it from drained the trans fluid. I'm going to take it out and check it out next weekend but just wondering if anyone else had this problem and if so what was wrong. Hoping its something simple that might not include a trans rebuild. Also how long does it take to remove the transmission from these things and how hard is it, just so I can prepare.
