No choice, then. I didn't want to. The Torque converter, the
differential, and the CV joints are all things I wanted to learn about
at a later date. I guess I need grease for the CV joints (may as well
do the wheel side as well, right?), got the final drive seals already
(and the pan gasket, though do I need that?), gear oil, what else?
Torque converter to final drive seal, flanges for the cv, governer
seal?... what?
