The 63 904 has the same issue - the air put into the rear clutch apply port
leaks to the front clutch apply port. I traced the passages through the front pump to the reaction shaft. The front clutch port comes out
on the reaction shaft between two seal rings and the rear clutch
passage comes out on the bore inside the reaction shaft.
My guess is the air leaks past the seal ring toward the
rear of the reaction shaft, then around the end and into the inside bore
in the reaction shaft. I am going to surmise this is a normal behavior
based on the premise it is unlikely both transmissions would be
broken in that same manner.
Is posting replies to your own questions as bad as talking to
yourself?
