This is a seal replacement at the rear servo cylindrical disk which is on the right rear side of the transmission. The cylindrical disk is easily pushed in and does not press hard against the outer lock ring. I have a steady flow of oil out through the servo.
edit:I forget the last sentence sorry. The cylindrical cover can easily be pushed in without an noticeable pressure on the rear servo, Is this normal and is this procedure possible with the trans bolted in.
This is a 722.4 thanks
