Description

Raybestos Number 122740-03K, for AS66RC, Gas Transmission. Secondary Pressure Regulator Plunger Valve Kit

Fits gas units only with .255″ dia. plunger valve, A worn secondary pressure regulator plunger valve sleeve in AS66RC, transmissions can cause reduced SLT pressure, TCC codes and shudder and overheating. The plunger valve is reacted on by SLT pressure, which allows throttle control of the converter charge circuit. As the OE sleeve wears, SLT pressure exhausts, compromising the converter charge circuit and resulting in the noted symptoms. Sonnax secondary pressure regulator plunger valve kit 122740-03K, restores the hydraulic control and fixes these issues.

  • Hardcoat anodized aluminum plunger valve combats premature wear
  • Upgraded sleeve material is highly wear-resistant to increase life

  • Plunger Valve
  • Plunger Sleeve

    Symptoms:

    • TCC codes
    • Converter shudder
    • Overheated fluid, bushings & converter
    • Low SLT pressure

    Cause:

    Bore wear in the boost sleeve allows SLT pressure to exhaust, preventing proper throttle-related control of regulated converter charge pressure.

    Correction:

    Sonnax secondary pressure regulator plunger valve kit restores hydraulic control by preventing SLT pressure to exhaust, restoring proper control of the converter charge circuit at the secondary pressure regulator valve.

    Warning:

    The AS66RC, (gas) and AS69RC, (diesel) secondary pressure regulator plunger valves are different diameters and should not be interchanged, as different converter charge pressures will result. Measure the plunger valve and/or reference sleeve slot to determine proper replacement kit.
