Ok so I opened up my trans to fix my manual valve body that wouldn't shift out of second gear, a few of the ***** were getting stuck. I put the trans back together and now it won't get into gear at all. I can shift out of park into reverse, the reverse lights come on, but when i give it gas it won't move itself back, it just rolls back from the hill it's on. In park it won't roll at all and in neutral, 1, 2, 3, and 4 it just rolls back down the hill and won't accelerate at all. Normally I would be able to fill the car shift out of park into a gear with a slight bang, but it doesn't have any bang at all. Anybody know what the problem could be? The only thing I can think of is that hook thing that hangs down that's supposed to connect to the piston in the valve body, maybe I hooked that up wrong? Any help appreciated, thanks.
