Trans doesn't go in gear. Now what?! Please Help

"went to put it in gear and nothing... It won't go into any gear, or reverse".
"The problem is that the shifter will move the trans lever, but nothing happens- the transmission won't go into gear."
I think I misunderstood your problem.
I assumed you took down a fully working trans, and had made no changes to it.
When you said "trans doesnt go in gear", I assumed you meant it had no drive.AS in propulsion.I think I may have assumed too much.
Diymirage may be on the right track.
I cant imagine how a manual valve could become disengaged on a Mopar trans with the VB installed.A GM yes. However, if the manual valve has become disengaged, it matches your symptoms better than anything else I put out there,so far.
So after the jackstand/linkage-disconnect test, If something seems amiss, a VB inspection might be in order.

Diymirage, good call.
