Symptoms:

  • Harsh shifts
  • Slipping gears

Cause:

Wear at the 1-2/4-5, 2-3 and/or 3-4 overlap control valve sleeves allows modulating oil pressure to exhaust.

Correction:

These modulating sleeves position the valve for proper clutch feed. Sleeve kits correct the wear condition and restore control of clutch pressure apply or exhaust.

Master Overlap Control Valve Sleeve Kit
Part No. 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
  • 2-3 Overlap Control Sleeve & O-Ring
  • 1-2, 4-5 Overlap Control Sleeve & O-Ring
  • 3-4 Overlap Control Sleeve & O-Ring
