Pressure regulator valve kit OS 722.6
• 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.
• 4-3 Neutral
• Delayed engagement
• No 2-3
• No lockup
• Slip codes
• Soft shifts under acceleration
A worn pressure regulator bore and/or valve.
The Sonnax kit salvages the worn valve body by restoring the hydraulic integrity of the pressure regulator circuit.
