722.6 Master Overlap Control Valve Sleeve Kit

Sonnax # 68942-05K

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 master overlap control valve sleeve kit 68942-05K restores necessary hydraulic control tolerances in the 1-2, 4-5 bore as well as the 2-3 and 3-4 bores.

• External O-ring provides additional positive sealing in the bore
• The OE spring and anodized valve can be reused

End-face notches on Sonnax valves allow for easy sleeve identification:

• One Notch = 1-2, 4-5 Sleeve
• Two Notches = 2-3 Sleeve
• Three Notches = 3-4 Sleeve
