After a few days wheeling last weekend I noticed some transmission fluid leaking out of the weep holes on the input side of the A442F on my '94 HDJ81. I'm guessing it's the input shaft seal (PN 9031142010?) but is there anything else I should plan on replacing while I'm in there? I already have the transmission pan gasket + filter on my list as well as the currently leaky speedo cable O-Ring but want to figure out if there are any other parts I should plan on having on hand to avoid extra down time.
