My 88...or 85...LOL..I can't remember which it is..anyway...it got stuck the other day too, I just popped off the top plate and put it back to where it needed to be, but I also put some special syn grease around where the shifters are through the plate and a bit around the blocks that actually shift the gears..nto a whole bunch that would contaminate the trans oil...but enough to stick to the moving parts and make everything work a whole lot better...mine was pretty dry up top and it shifts smother now
