Okay I repaired rear main seal and I put a new clutch plate and a new slave cylinder in my truck it's a 1994 2.3 5 speed okay I rocked my shifter back in forth believe it's in neutral I started the truck my tire is rolling at idle speed and the trucks in neutral cant go into reverse

 

This one is strange....

this is a stupid question but is the trans evenly bolted to the block??

it sounds like you physically can't move the stick because it's contacting the frame.... how are your motor mounts? Is it possible the engine shifted when you pulled the trans?
