ACDelco Dexron VI Full Synthetic Automatic Transmission Fluid 1 Gal — GM Original Equipment, Improved Shear & Oxidation Resistance

ACDelco GM Original Equipment Dexron VI full synthetic automatic transmission fluid is a GM-engineered ATF formulated to meet modern transmission demands while remaining backward compatible with older Dexron specifications.

This one-gallon ACDelco fluid (part 10-9244, cross 88865618) is manufactured to General Motors’ standards for fit, function, and performance. It’s part of the GM Original Equipment lineup and replaces older Dexron fluids with improved shear stability, oxidation resistance, and friction durability. The formula is designed for automatic transmissions in many GM cars, light trucks, and SUVs and is intended for both service and rebuild applications where a Dexron VI fluid is specified.

How does Dexron VI differ from earlier Dexron fluids?

Dexron VI is a significant upgrade over previous Dexron formulations, offering enhanced chemical and mechanical stability. It reduces breakdown under heat and shear, helping maintain proper lubrication and friction characteristics over longer intervals.

• Improved viscosity stability for consistent hydraulic performance.
• Better oxidation resistance to extend fluid life under high temperatures.
• Enhanced foam and aeration control to protect valves and clutches.
• Optimized friction durability for more reliable shift quality.

Will this ACDelco ATF work in older vehicles that used Dexron II/III?

Yes — Dexron VI is backward compatible with many older Dexron specifications, making it a straightforward replacement in transmissions originally filled with earlier Dexron fluids. However, always confirm the vehicle manufacturer’s recommendation before switching fluids.

• Designed to be used where prior Dexron fluids were specified.
• Provides upgraded protection compared with older formulations.
• Ideal for service fills and transmission rebuilds when Dexron VI is acceptable.
• Check the owner’s manual or service data for exact compatibility.

What performance benefits can I expect from using this full synthetic ATF?

Using a full synthetic Dexron VI fluid helps protect internal parts and maintain consistent shift performance across a wide temperature range. The formulation targets wear protection, shear stability, and reduced oxidation for longer service life and dependable operation.

• Anti-wear additives help preserve gears, clutches, and valve body components.
• Shear-stable base oils keep viscosity within spec under heavy loads.
• Reduced aeration and foaming improve hydraulic response and shift quality.
• Lower oxidation improves fluid longevity and reduces sludge formation.

How should I store and handle this transmission fluid?

Keep the one-gallon container sealed and stored upright in a cool, dry place away from direct sunlight and extreme temperatures. Use clean tools and funnels during service to avoid contamination and follow local regulations for disposal of used ATF.

• Store indoors between recommended temperature ranges to preserve additives.
• Use a clean funnel and avoid introducing dirt or water into the transmission.
• Dispose of used fluid at authorized recycling or waste facilities.
• Replace the cap tightly after use to maintain product integrity.

Who is this for: ACDelco GM Original Equipment Dexron VI full synthetic ATF is suited for technicians, DIYers, and fleet managers working on GM vehicles — and for anyone maintaining older transmissions that originally required Dexron fluids but need improved modern protection. If your vehicle’s service specification calls for Dexron VI (or a compatible Dexron spec) and you want a GM-backed, OE-level fluid engineered for long-term durability and consistent shift performance, this one-gallon ACDelco product is an appropriate choice.
