This will give you an idea of why you should do a tear down now and then. Big Daddy had already cleaned the inner primary before we decided to separate the trans from it. This is what he missed. Water had become trapped in the cavity along the bottom side of the trany, and was deteriorating the metal. I have tried just about everything you can imagine to clean the stains off a trany, but magnesium just won't shine. Big Daddy took my dremel and a little wool bit with polishing compound and it came out pretty good. Throttle cable ends had a bit of rust on them. Left one is before, and the right one is after scrubbing it with WD-40 and aluminum foil. Sorry, didn't get a stopping point picture, just have to wait till tomorrow.
