About to pull my tranny and would like to rebuild it myself. I have a shop manual and think i will have to replace 1st gear and cluster. Anyone tackled one of these and how difficult. I know parts are going to be hard to find, but really want to keep this setup. Any advise.

I have had mine apart, the overdrive planetary gear was bad in mine. The front is basically a regular 3 speed.

Here are some links to help you.
