Description
Premium automatic transmission fluid meeting GM Dexron II specifications.
Castrol Dex 2 ATF is a high-performance automatic transmission fluid formulated to meet or exceed General Motors Dexron II specifications. This specialized fluid serves multiple critical functions within the transmission system: it acts as a hydraulic medium to transfer power, a coolant to dissipate heat, a lubricant to protect moving parts, and a friction modifier to enable smooth shifting. The advanced formulation contains a carefully balanced additive package that protects metal surfaces from wear while maintaining precise friction characteristics needed for clutch engagement. Its exceptional oxidation stability helps the fluid resist breakdown even at the high temperatures generated within automatic transmissions, which can often exceed 175°C in severe service. This resistance to oxidation prevents the formation of varnish and sludge that can clog valves and inhibit proper hydraulic function. The fluid’s viscosity modifiers ensure it maintains proper flow characteristics across a wide temperature range, from cold-weather starts to high-temperature highway driving. This 5L container provides enough fluid for a complete transmission service on most vehicles. Beyond transmissions, this versatile fluid can also be used in power steering systems, hydraulic systems, and certain manual transmissions that specify ATF as the recommended lubricant.
