Overlap Valve kit 3-4 722.6
• Plunger Valve & Sleeve Assembly
• Overlap Valve
• Spring
• O-Ring
The 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 valves, controlled by EPC (modulated pressure) and shift valve pressure, are used to gradually reduce the pressure to the disengaging clutch.
Symptoms:
• 3-4 Bump
• 3-4 Flare
• 3-4 Harsh
• Slipping
Cause:
Wear at the overlap valve bore prevents proper exhaust of the disengaging clutch pressure, altering the precise timing required in the clutch-to-clutch shift transition.
Correction:
The improved Sonnax overlap valve kit restores hydraulic sealing integrity and valve timing when installed in a refurbished bore.
Required tool:
F-68942-TL31
