Havoline® ATF III-H is a proven performance Automatic Transmission Fluid formulated for applications that call for the former GM DEXRON®-III H, MERCON® and Allison C-4 fluids. It is formulated with high performance mineral base oils and a specially balanced additive combination to provide exceptional oxidation resistance, extended oil life and good wear protection.

Havoline ATF III-H is designed for use in automatic transmissions that require a GM DEXRON®-III H type fluid. Although this specification has been made technically obsolete by GM itself, many equipment manufacturers continue to recommend fluids of this type. It can be used in transmissions that require a Ford MERCON® fluid. The product is not recommended for transmissions that require a Ford MERCON® V fluid (this is a separate specification to MERCON®). Due to fundamental differences in frictional properties, it should not be used in applications that require a Ford M2C33-F/G fluid. Havoline ATF III-H is also suitable for use in power steering systems that require a mineral-type Power Steering Fluid. It should not be used in steering or active suspension systems that call for specific semi-synthetic or synthetic fluids, as the response speed may not be sufficiently fast. Havoline ATF III-H may also be used as a wide temperature range anti-wear hydraulic fluid for mobile, industrial and marine applications. The viscosity corresponds to ISO VG 32.
