Continuous plunger valve oscillation causes wear at the overlap control valve sleeves, allowing modulated oil pressure to exhaust or oppose the shift and create numerous shift complaints in Mercedes 722.6 units. The highly wear-resistant Sonnax 2-3 overlap control sleeve kit 68942-03 restores necessary hydraulic control tolerances.
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.
