ACDelco DEXRON-VI Auto Fluid

ACDelco DEXRON-VI Automatic Transmission Fluid is the most recent release in the well-established DEXRON series of automotive transmission fluids. It provides more consistent shift performance, even in extreme conditions, and degrades less over time. DEXRON-VI Automatic Transmission Fluid helps automatic transmissions last longer and perform better. DEXRON-VI Automatic Transmission Fluid is 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) fluids), and recommended for any other vehicle manufacturer that calls for DEXRON-VI, III, or II(E). ACDelco DEXRON-VI Automatic Transmission Fluid is not for use in CVT (Continuously Variable Transmissions) or DCT (Dual Clutch Transmissions) which require specialized fluids.


• Backward compatible with previous DEXRON automatic transmission fluids and can be used as a much-improved replacement for older vehicles/transmissions originally using previous DEXRON fluids.
• Improved performance over previous DEXRON fluids in: friction durability, viscosity stability, aeration and foam control, and oxidation resistance.
• Potential to enable improved fuel economy and longer transmission life.
• Provides for extended drain intervals.


• Causes of transmission fluid degradation include overall thermal stress, mechanical shearing, and contamination.
• Mechanical shearing affects the fluid’s viscosity modifiers, causing the fluid to thin.
• Common sources of contamination include metals and other engine fluids.
• Coolant contamination is particularly harmful and usually requires a complete overhaul or even replacement of the transmission.
• Signs that transmission fluid should be replaced include: transmission grinding or making strange noises, problems shifting gears, gears slipping, vehicle lurching forward or falling back, delays in vehicle movement, and/or continued usage beyond the recommended fluid change timing.


• Transmission fluid should be replaced when it becomes contaminated.
• Anything but transmission fluid in the transmission is considered a contaminant.
• Always use the recommended type of transmission fluid in your vehicle, as referred to in your owner’s manual.


Q: Does my transmission fluid need to be changed as regularly as my oil?
A: No. Transmission fluid is designed to last much longer than most engine oils. Always refer to your vehicle owner’s manual to identify how often and when your transmission fluid should be changed. Severe usage and regular usage descriptions are provided.
