OE 4T60-E shift valves have changed materials over the years, starting with steel, changing to silver-colored uncoated raw aluminum, and finally anodized aluminum. 4T60-E 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. It is highly recommended to replace all raw aluminum shift valves with the Sonnax hard-coat anodized replacements. These are drop-in replacements and do not require any machining. Valves also have applications in 4T60-E and 4T65-E.

  • Sonnax valves use a hard-anodized finish to reduce wear and friction
  • Valves incorporate annular grooves to center the valves and reduce sticking caused by side loading
  • Material: Aluminum
