Swapped out the leaking Park cable on my 904 Torqueflite....

Is it "normal" for transmission fluid loss to occur when you remove the housing cover lower plug?

Tech manual had no instruction calling for a catch can or anything.

(I have no idea) :lol:
Ya, pretty much anything you remove from the transmission that has internal parts will dribble some ATF except the vent on top of the case! :poke::lol:
