904 tranny problems

We're pretty heavy into doing it right. You get that kd adjusted right; with the right linkage, and you'll think you got a shift kit. Course that's after you drop out that front drum and replace the frictions...easy peasy.
Easy for you I don't know what the front drum and frictions are but I guess I'll find out.
I'd like to fix it myself just to learn but am afraid of screwing up again.
