In Mercedes 722.6 units, excessive valve-to-bore clearance at the modulating pressure area allows modulated solenoid feed pressure to exhaust, reducing line pressure and creating shift-related complaints. Bore wear at the inner spool results in high line pressure conditions. Sonnax oversized pressure regulator valve kit 68942-07K salvages the valve body with an oversized hardcoat anodized valve and recalibrated springs.
- Outer spool has extended length for better support
- Hardcoat anodized aluminum valve combats premature wear
- Valve spools have annular grooves to prevent future side-load wear
