Default No reverse

Hi everyone, this is my first post here. I have an '87 GN that won't go into reverse. It worked fine the last time I drove the car a few months age, then I had the engine apart to replace a piston, now it's back together and running but it won't back up. I can feel a slight bump when reverse is selected, and the wheels will spin if the car is jacked up but there's not enough power to make it move. I had the engine oil pan and the driver side head off to replace the offending piston, but I can't imagine how that could have afffected reverse gear in the trans? The car was on jackstands- front end only- for a couple of months while it was apart, and a friend suggested that maybe an o ring or seal dried out in the trans? A long shot, to me, but then again I have no explanation at all... Anyone have any ideas about what the trouble is and how to fix it?

Exclamation Re: No reverse

How many miles are on the car?

Has any work been done to the transmission in recent history?

The reverse circuit utilizes pressure from a tube that goes underneath the throttle body. If the clip that secures this tube is not present, the tube might work loose on one end and pop out. That would leave you with no reverse. It would also chew up clutches.

That is one possibility, anyway...
