To expedite the process and because I'm feeling really lucky, I'd like to order the basic parts anyone with experience would replace when opening one of these 4 speed transmissions. What would you with experience replace as standard practice?
Nothing except gaskets and not every time either.
If your pockets are deep you can order kits but I have been using the same parts for decades, including bearings and seals. And synchronizers by repointing, back-cutting, and shuffling brass around.
Those are killer-tough transmissions.
If you are on a time-table, you're in the wrong hobby,lol.
