The ZF9HP48 PBW (Park By Wire) and PBC (Park By Cable) have different plunger diameters and should not be interchanged.
Chrysler 948TE, Honda/Acura, 9-speed and ZF9HP48 transmissions are equipped with an aluminum sleeve for the A and F dog clutch plunger valve. This material is prone to wear from valve plunger reciprocation. Failure of this sleeve results in a variety of shift problems and solenoid codes. Sonnax A & F dog clutch plunger valve kit 85740-05K restores the correct hydraulic clearance and proper function of the assembly.
Visible wear or scratches are found on the I.D. the sleeve or O.D. of the plunger.
