In Ford 6F50, 6F55 and GM Gen. 1 6T70 and 6T75 units, AFL/solenoid pressure regulator bore wear results in low pressure at the shift and control solenoid valve assembly. The OE valve has a large reaction area and is highly affected by side-loading which wears the valve body bore. As the bore wear increases, oil pressure is reduced to the shift solenoids, which causes solenoid and ratio codes. This also results in low line pressure. Installing Sonnax AFL/solenoid pressure regulator valve kit 124740-32K renews the hydraulic integrity of this circuit, restoring normal shift operation and feel. This drop-in, sleeve/valve assembly provides a new and unworn bore for hydraulic sealing of the valve while the sleeve seals off existing moderate bore wear to prevent fluid loss. A new spring to provide correct limit pressure with the sleeve/valve assembly is also provided. Hardcoat anodized aluminum valve combats premature bore wear Highly wear-resistant billet sleeve seals bore from wear-related fluid loss and provides a new, unworn bore for the valve to operate within New spring provided for correct limit pressure Drill and plug included to allow for quick rerouting of balance oil at the separator plate Drop-in Zip Valve™ parts install quickly and easily
