NO TOOLING REQUIRED
GM 4T60-E and 4T65-E shift valves have changed materials over the years, starting with steel, changing to silver-colored uncoated raw aluminum, and finally anodized aluminum. These units can have a combination of these materials with the silver-colored uncoated raw aluminum being especially problematic due to scoring/scratching and intermittent sticking. Sonnax 3-2 manual downshift valve 84754-37K eliminates surface wear and reduces valve hang up.
- Hardcoat anodized aluminum valve combats premature wear
- Annular grooves to center the valves and reduces sticking caused by side loading
- Drop-in Zip Valve™ installs quickly and easily

CAUSE

CORRECTION
