Sonnax High Limit Feed Valve 10L1000

Sonnax Feed Limit High Valve Kit

Restore proper transmission hydraulic pressure and clutch operation with the Sonnax Feed Limit High Valve Kit 105740-58K. The factory feed limit high valve regulates line pressure supplied to the boost ball system for the "C" and "F" clutch controls. Excessive valve bore wear can cause pressure leakage, resulting in shifting problems and potential clutch failure.

This upgraded kit corrects circuit pressure loss and restores proper valve operation. Featuring a hardcoat anodized aluminum valve, wear-resistant sleeve, and replacement spring, it provides improved durability while maintaining original equipment pressure and functionality. The drop-in Zip Valve design allows for quick and convenient installation.
