Uncontrollable throttle pressure due to oil loss is a common complaint in vehicles with Ford AOD transmissions. This results in low line pressure and poor throttle and shift timing adjustments. The hardened steel throttle valve plug continuously reciprocates within the aluminum throttle valve sleeve, wearing the inside diameter of the sleeve. This wear allows throttle valve feed oil to leak past the plug and exhaust, resulting in poor line rise. This excessive leakage can be eliminated by installing Sonnax throttle valve plug kit 76989K.

The throttle valve sleeve is manufactured from high-quality aluminum to prevent wear
O-Rings added to the outside diameter of the sleeve prevent feed oil from escaping past the valve body bore
Steel plug has been tightly toleranced to allow minimum clearance with the inside diameter of the sleeve, thus restoring the hydraulic integrity of the assembly
Drop-in Zip Valve™ parts install quickly and easily
