Fits ’94-later 4T60-E. Does not fit 4T65-E Geartronic® or Tapshift® units.

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 valves combat premature wear
• Annular grooves to center the valves and reduces sticking caused by side loading
• Drop-in Zip Valve™ installs quickly and easily
