Sonnax 77966-94K Throttle Valve Plunger Valve Kit for GM 700-R4 4L60

The Sonnax 77966-94K Throttle Valve Plunger Valve Kit is designed to restore proper line pressure and eliminate shift problems in GM THM 700-R4 and 4L60 automatic transmissions. This complete kit is specifically designed as a replacement for OE throttle valve plungers with code "94".

Addresses Common Transmission Issues:

In stock 700-R4 transmissions, the steel throttle valve plunger continuously reciprocates within the aluminum sleeve, causing wear that allows throttle valve feed oil to leak past the plunger. This results in poor line rise, insufficient throttle pressure, problematic detent downshifts, and can ultimately lead to 3-4 clutch failure. The weak OE spring compounds these issues by failing to maintain adequate line pressure.

Key Features:

• High-quality aluminum sleeve engineered to prevent wear and restore hydraulic integrity
• Tightly toleranced sleeve and plunger design eliminates oil leakage
• Upgraded throttle valve spring maintains higher line pressure for improved TV performance
• Drop-in Zip Valve™ installation for quick and easy replacement
• Complete kit includes spring, sleeve, and plunger

This kit provides a reliable solution to restore proper throttle valve operation, ensuring smooth shifts and preventing costly clutch damage in your GM 700-R4 or 4L60 transmission.
