Vehicles with listed Chrysler units may have problems with slippage in Reverse, poor cooler charge at idle, and high or low line control. These concerns are often due to excess wear at the line pressure plug and sleeve. When this sleeve and plug wears, leakage past the plug prevents the pressure regulator valve from properly controlling line pressure.
Sonnax line pressure plug and sleeve kit 22229-04K restores hydraulic integrity to the circuit, providing renewed line pressure control in all ranges.
This kit fits Chrysler A727 units with boost tube only and 42-46-47RH/RE units with .264" plug diameters.
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.
Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
