Actually both the piston and reaction valve can be replaced without removing the transmission. As Mike mentioned some partial disassembly of the transmission is required, but it can be done in the car. I am assuming that it is a 722.3xx series. Let me know if you want details.
BTW I never got a response to my earlier questions.
I got too many cars!! Insurance eats me alive. Dave
