When it comes to transmission fluids, one size doesn’t necessarily fit all.

That’s why, when servicing a customer’s transmission, it’s important to check the specification to make sure you’re using the right fluid. A misapplication could cause performance issues.

With that in mind, ACDelco offers a range of high-quality fluids for a variety of transmissions — from automatic to manual to dual clutch — that are designed to keep the gearboxes running smoothly.

For example, ACDelco GM OE DEXRON®-VI, DEXRON® ULV and ACDelco Gold ATF III automatic transmission fluids:


• Feature a synthetic formulation with high shear stability and oxidation resistance

• Provide superior year-round protection and performance

• Offer anti-wear protection to extend equipment life

• Help ensure smoother shifting and reduced shudder

• Help extend service life and performance

ACDelco DCT FFL-4 for Corvette
In addition to the above, ACDelco offers DCT FFL-4 transmission fluid that’s designed for the Chevrolet Corvette C8, which is equipped with an advanced dual-clutch transmission that employs friction plates/clutches instead of a torque converter to launch the vehicle.

FFL-4 is vital for the proper maintenance and operation of the C8’s dual-clutch transmission and provides the correct chemistry to properly protect it. The fluid also optimizes gear wear while enhancing friction stability for extended intervals at different temperatures.
