Is it likely that I could rebuild my muncie 4sp.? I have average motor & chassis building skills & can't afford to pay to have it done.

P.S. the trans. is still working, but jumps out of 4th gear.

Thanks

Sounds like your synchros and/bearings are worn. Working on the Muncies isn't that hard. I used the GM manual which had the exploded diagrams. The only time I had a problem was with the 100 or so (loose) needle bearings that are between the input shaft and the output shaft. Patience my son!

I rebuild my first Muncie when I was 17. Never did one before. They are straight forward and easy. Require no special tools.

Muncies are a piece of cake, one of the easiest transmissions there is to work on...go for it. Heavy grease solves the needle bearing problems.

One thing to look for is when it is jumping out of gear along with the things others have said is if the shift forks are worn it will not be fully in gear and will jump out. Also if the shift collars are worn it does the same thing. When you get it apart check those and let us know.

Thanks all, you've given me the confidence to do it my-self.

This is a great site for information and parts on the Muncie.

The rebuild video is a great asset for the first timer, I suggest you get it.

My Muncie ('68 model) needed a special wrench to remove the nut on the input shaft in front of the front bearing. I used vise-grips & it worked out OK. The snap rings worked better with a snap ring tool from Sears.
