I believe want Kent meant to say was differential oil getting past
seal and mixing with auto trans fluid. This was a common issue with
earlier type 44(5k/5kt) 3-speed trannies. IIRC there was a seal that
would harden over time and allow the fluids to mix. Problem was, you
could check the fluid level and it was ok (but it's composition was
not).
