Bore wear at compensator feed regulator valve allows critical pressure loss that prevents proper clutch timing and control.
Recover hydraulic control and renew shift performance by installing Sonnax compensator feed regulator valve kit.
Compensator Feed Regulator Valve Kit
- Retaining Clip
Listed GM transmissions incorporate a low-pressure compensator feed circuit to assist clutch return springs during release of rotating clutches. After clutches disengage, the compensator feed circuit maintains pressure in the clutch release cavity to oppose centrifugal application of the clutches. Control over this process resides with the compensator feed regulator valve. When the bore wears, correct valve operation is hindered, causing clutch apply timing issues such as harsh shifting, flares, and bump shifts. In addition, overheated fluid and burned clutches can result. Installing Sonnax compensator feed regulator valve kit 104740-09K restores normal compensator action for revived shift characteristics in all ranges.
- Hardcoat anodized aluminum valve combats premature wear
- Highly wear-resistant aluminum sleeve provides additional valve support
- Includes calibrated spring for restoring OE compensator pressure
