Uncontrollable throttle pressure due to oil loss is a common complaint in vehicles with an AOD transmission. 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.

Throttle valve plug and sleeve kit eliminates excess leakage
Sleeve has been manufactured from a special aluminum designed to prevent wear
Steel plug has been tightly toleranced to allow minimum clearance with the inside diameter of the sleeve, restoring hydraulic integrity to the assembly
