The Mercedes 722.6 transmission uses clutch-to-clutch transitioning during shifts, so timing is very critical to prevent shift complaints like flares or bind-ups. The overlap control valves, controlled by EPC (modulated pressure) and shift valve pressure, are used to gradually reduce the pressure to the disengaging clutch.
Sonnax oversized 3-4 overlap control valve kit 68942-31K has slightly longer critical spool diameters and optimized annual groove placement for better hydraulic sealing.

The wear-resistant plunger sleeve has an added O-ring to provide additional positive sealing in the bore
The replacement spring and valve ratios maintain OE shift pressures for proper timing and function
