Transmissions have many demands placed on them. That’s why PEAK® DEXRON® III/MERCON® Automatic Transmission Fluid is formulated with select, highly refined base oils and specially balanced additives, as well as friction modifiers that provide smooth lockups required by both Ford and General Motors. PEAK® DEXRON® III/MERCON® Automatic Transmission Fluid (ATF) is recommended for use in automatic transmissions in GM, Ford (except where Ford M2C33-F is specified) and other domestic and foreign vehicles requiring DEXRON® III, IIE AND II, as well as MERCON® ATF. Additionally, it can be used in Allison automatic transmissions – including those requiring C-4 fluid – and Caterpillar transmissions specifying T0-2 performance.

Always refer to your equipment’s owner’s manual for specific information on Automatic Transmission Fluid requirements. Because it has a high viscosity index, PEAK® DEXRON® III/MERCON® ATF can be used over a wide temperature range – providing excellent low-temperature fluidity while retaining desired viscosity at high temperatures. Specific benefits and product attributes include:

        • Smooth shifting performance where DEXRON® III or a MERCON® fluid is specified
        • High-temperature oxidation resistance
        • Excellent corrosion, wear, and rust protection
        • Compatibility with automatic transmission components, including elastomer seals and plastic parts

Always consult your owner’s manual for Automatic Transmission Fluid requirements.
