ACDelco Dexron VI Transmission Fluid

Backward compatible with previous DEXRON automatic transmission fluids and can be used as a replacement for older vehicles/transmissions originally using previous DEXRON fluids, ACDelco Dex VI provides consistent shift performance, even in extreme conditions.

Suitable for use in vehicles that specify the following requirements:
  • Fully licensed and approved by GM,
  • Recommended for use in GM transmissions model year 2006 and newer calling for DEXRON-VI Automatic Transmission Fluid (replaces DEXRON-III and DEXRON-II(E)
  • Recommended for any other vehicle manufacturer that calls for DEXRON-VI, III, or II(E).
Not for use in CVT (Continuously Variable Transmissions) or DCT (Dual Clutch Transmissions) which require specialized fluids.

Maintenance Tips:

  • Transmission fluid should be replaced when it becomes contaminated.
  • Anything but transmission fluid in the transmission is considered a contaminant.
