Mobil Type F ATF is an automatic transmission fluid which is made from high
quality base oils with viscosity index improvers, antioxidants, anti-wear
agents, defoamants and special additives to provide the controlled frictional
characteristics of a Type F fluid in automatic transmission applications.

| | Applications
The frictional characteristics of an automatic transmission fluid are an
important factor in the design and operation of the transmission. All Ford
Motor Company transmissions built prior to 1977, and certain models that
continued in use during 1977-1980, were designed for a high-friction fluid
that allowed the shifting clutches to lock up or engage quickly. Ford
specification ESW-M2C33-F covers this type of product, which is commonly
referred to as "Type F" fluid. Mobil ATF Type F is the appropriate product for
these units.
These Ford vehicles are identified as:
-
All 1976 and earlier Ford, Lincoln, and Mercury models of cars, vans, and
light trucks.
-
All 1977-1980 Ford models having either ESW-M2C33-F or no number at all
stamped on the transmission dipstick.
Mobil ATF Type F is also recommended for automatic transmissions in certain
older Toyota, Mazda, Volvo, and other imported vehicles that require an
ESW-M2C33-F fluid. In addition, this type of ATF is specified for some Ford
power steering systems.
Mobil ATF Type F is recommended for both makeup and refill in power steering
systems of the following Ford vehicles:
- 1980 and older Lincoln, Continental, and Mark;
- 1978 and older models of all other Ford cars, vans, and light trucks.
Mobil ATF Type F meets the anti-wear requirements of Sperry Vickers industrial
hydraulic systems where low wear in the ASTM D 2882 vane pump test is the
principal criterion.
Mobil ATF Type F is not recommended for automatic transmissions in Ford,
General Motors, Chrysler, American Motors, or any other cars requiring a
Dexron-II, Dexron-IIE, Dexron-III or Mercon-approved fluid, or for those Ford
products requiring an M2C138CJ (Type CJ) fluid or an M2C166H (Type H) fluid.
For the above applications, Mobil ATF D/M (Dexron/Mercon) or Mobil
Multi-Vehicle ATF are recommended.
Automatic transmissions should be checked for proper fluid levels at regular
intervals, and the fluid should be changed at manufacturer-recommended
intervals. However, this may vary due to your vehicle's operating conditions.
Some manufacturers recommend more frequent changes of transmission fluid under
severe driving conditions, such as heavy traffic, hot weather and trailer
pulling.
