- Low line rise
- Overheated band
- Overheated clutch
- TV pressure imbalance
- Uncontrollable shift timing
The throttle valve plug wears the sleeve, allowing throttle valve feed oil to leak past the plug and exhaust.
The replacement kit has been designed to eliminate excessive leakage and includes a tightly toleranced, wear resistant sleeve.
Throttle Valve Plug Kit
Factory style sleeve, no o-rings
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 excessive leakage.
- Replacement 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
