This one really isn't about the 722.1; but it is similar enough that the majority of the procedures will work. The main differences are in the gear train, valve body, and the K2 clutch. When I get my transmission up and running correctly, I would be happy to do a write up on the 722.1 if someone is in need of an overhaul on their transmission. I've had this one apart enough times that at this point I could assemble a 722.0 from parts thrown in a box (with the exception of the selective spacers and band pins). I think (but can't confirm) that on my unit the K2 clutch was partially turned on in first gear for some reason. Especially since it had a weird engagement when placed in "D".
