The ZF9HP48 PBW (Park By Wire) and PBC (Park By Cable) have different plunger valve diameters than Chrysler applications and should not be interchanged.
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 85740-22K restores the correct hydraulic clearance and proper function of the assembly.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
Visible wear or scratches are found on the I.D. the sleeve or O.D. of the plunger.
