Looking for diagnosis
 

Hey,

I have a little 1990 Toyota pickup I am getting ready tosell. The thing runs great. I just drove it to Arizona last weekend. Anyways, I noticed a problem I want to fix before I sell it. In certain situations the car doesn't want to stay in gear. For example, you put it in first gear and start going and it falls out of gear all the sudden. It has happened in other gears a couple times but usually first. Thoughts?

Sounds like a synchro problem.
