Castrol ATF Dex III automatic transmission and power steering fluid is designed for use in most GM automatic transmissions prior to 2005 as well as a range of other automatic transmissions from many different makes and models that require either DEXRON® II, DEXRON® III or where MERCON® performance is recommended. Castrol ATF Dex III has been formulated to offer enhanced friction durability to both promote smooth shifting and extend the life of your transmission.

Castrol ATF Dex III can be used for power steering systems that don’t require specialist fluids and recommend ATF or DEXRON® (II or III) specification fluids. It is also suitable for use in some manual transmissions that require a DEXRON® (II or III) automatic transmission fluid.

To find the transmission fluid suggested for your vehicle; either add your vehicle to My Garage or check with your manufacturer, vehicle user manual, your local mechanic or head in-store and talk to one of our friendly team.
