Medatronics Corporation strongly recommends Mobil1 ATF in all JT5 applications.

Product Description

Mobil Multi-Purpose ATF is a new generation, premium automatic transmission fluid meeting major U.S. and import car manufacturers' performance requirements. It is formulated from special, high-quality base oils combined with viscosity index (VI) improvers, antioxidants, antiwear agents, detergents, and defoamants. The product contains special friction modifiers or lubricity agents to control the transition from full film to thin film lubrication as a vehicle's band and clutches are activated during shifting. This ensures consistent, smooth shifts under a broad range of driving conditions, temperatures, and transmissions.

Mobil Multi-Purpose ATF provides excellent performance under very low temperatures to ensure smoother, more consistent all-weather shifting, as well as improved all-around lubrication of components and longer unit service life. Mobil Multi-Purpose ATF also offers excellent oxidation stability, meeting the more severe requirements for warranty protection in most late-model cars. Mobil Multi-Purpose ATF is qualified by General Motors Corporation as a Dexron III fluid. It is qualified by Ford for its Mercon requirement and may be used in cars requiring Ford Type CJ and H fluids.


Mobil Multi-Purpose ATF is recommended for make-up and refill in 1974 and later General Motors cars and light trucks. It also is recommended for make-up and refill in 1988 and later Ford and other vehicles requiring Mercon, as well as 1981 and later Fords requiring an M2C138CJ or M2C166H fluid. Mobil Multi-Purpose ATF may be used in other domestic and imported cars that require a Dexron III, Mercon, or Ford Type H fluid.

Mobil Multi-Purpose ATF can be used in off-highway transmission, power steering, and other hydraulic systems requiring a Dexron III or Allison C-4 fluid. It meets the exacting industrial hydraulic oil demands of Denison HFO, Vickers vane, and Sunstrand piston pumps.
