SonnaxValve KitPart #: S104741LK

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 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 Drop-in Zip Valve™ parts install quickly and easily
