Ok, first off it's not a Chev or GMC tranny, but please give it a thought.

My daughter's '87 YJ (Wrangler) Jeep with the 5 speed Puegot trans is stuck. She drove it last night, got in to leave where she was at and pulled the shifter out of 1st to go into reverse and it wouldn't go. She says the shifter felt like it hit nuetral, but wouldn't go over far enough to go into reverse. The gears actually stayed in first. She ended up driving home last night all the way in first.
The shifter has side to side movement as if in a tighter than normal nuetral and only a little bit of fore and aft movement like it's in gear. I pulled the shifter out and it's not broken or bent. I can't see very well in to the trans and but there are no obviously bent or broken pieces. Rocking or playing with the clutch both running and off doesn't do anything.
I've searched Jeep sites and will keep looking.
Thanks in advance.
