    Pressure Regulator Valve

    The OE pressure regulator valve is prone to rusting in the bore of valve body cores, and is often prone to damage during removal. This direct replacement pressure regulator valve allows salvage of these cores. Slight modifications to the size, number and location of the annular grooves provide better hydraulic sealing and prevention of side-loading for this replacement valve.

    • Replacements not available
    • Improved hydraulic seal
    • Reduced side loading
    • Drop in replacement with improved tolerances


    Manufacturer's Part Number:

    The OE boost sleeve wears from repeated oscillation of the boost valve. This wear allows leakage, reduces line pressure and contributes to line pressure instability. Sonnax Boost Valve Kits replace worn components and incorporate a larger boost ratio, which increases line pressure and provides firmer shifts. Sonnax also offers replacement manual and regulator valves.
