Thanks. Funny thing about the 4 speed transmission. When I bought the car 2nd hand it started in first and ran only to third. The owners manual says that the 380's start in first while the 500's start in second. Now I have just replaced the B2 piston (with sleeve and seal) as well as the K1 kit, it starts in second and runs to fourth. First is there, but only on kick-down. The thing now is that it sems to "clunk" a bit at low speed between 2-3 and with little to no accelerator pressure.
