THE OE FEED LIMIT LOW AND HIGH VALVES ARE AT HIGH RISK FOR PREMATURE WEAR AND FAILURE. REPLACE BOTH VALVES IN EVERY BUILD EVEN IF THERE IS NO TRANSMISSION PROBLEMS AND THE VALVE PASS A VACUUM TEST.

The feed limit high valve in listed GM transmissions limits line pressure feed to the boost ball system for "C" and "F" clutch controls. Excessive wear in the feed limit high valve bore allows pressure leakage, which can be the source of shift problems and clutch failure.
Installing Sonnax oversized feed limit high valve kit 105740-60K corrects circuit pressures and restores proper valve functions.
- Hardcoat anodized aluminum valve combats premature wear
