Pressure regulator valve kit OS 722.6

Pressure regulator valve kit OS 722.6 • Valve • Inner Spring • Outer Spring Fits bores containing OE PR valve with .512" dia. spool only. 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. The Sonnax kit 68942-07K salvages the valve body with an oversized hard-anodized valve and recalibrated springs. • Outer spool has extended length for better support. • Aluminum valve has been hard-anodized to prevent excessive wear. • Valve spools have annular grooves to prevent wear due to side loading. Symptoms: • 4-3 Neutral • Delayed engagement • No 2-3 • No lockup • Slip codes • Soft shifts under acceleration Cause: A worn pressure regulator bore and/or valve. Correction: The Sonnax kit salvages the worn valve body by restoring the hydraulic integrity of the pressure regulator circuit. Required tool: F-68942-TL7
