'91 pickup, 2wd, manual trans, keeps popping out of gear when driving. No leaks, no clutch slipping, under 100k original miles. What's going on?

 

Remove the shifter and inspect the shifter seat and bushing. IF they are worn (probibly are) then replace with a new upgraded set from www.marlincrawler.com

Probibly the most recomended mod (if you can call it that) to our trucks. You would be amazed how many people have been told their trans is going when its thoes two simple $20 parts..

 

Thanks, I'll try it.
