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 2-3 shift valve 84754-36K 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
