What does type F mean in transmission fluid?
Type F transmission fluid refers to a specific type of automatic transmission fluid (ATF) that is designed for use in certain Ford and Mazda vehicles. This fluid has unique chemical properties and performance characteristics that make it suitable for the transmissions in these vehicles.
Understanding Transmission Fluid Types
Transmission fluids come in various types, each designed for specific vehicle applications. The type of fluid required is determined by the transmission design, materials, and operating conditions. Using the wrong type of fluid can lead to transmission problems, so it's important to follow the manufacturer's recommendations.
What is Type F Transmission Fluid?
Type F transmission fluid is a specialized ATF developed by Ford for use in their automatic transmissions, particularly those found in Ford, Lincoln, and Mercury vehicles. It was first introduced in the late 1960s and has since been used in various Ford and Mazda models. Type F fluid is formulated to provide the following key properties:
- Improved friction characteristics for smooth, consistent shifting
- Enhanced oxidation and thermal stability to withstand high temperatures
- Compatibility with the materials and components used in Ford/Mazda transmissions
- Specific viscosity and flow characteristics required for proper lubrication and operation
Using the correct Type F fluid is crucial for the proper functioning and longevity of the transmission in these vehicles.
Identifying Type F Transmission Fluid
Type F fluid is typically red or reddish-brown in color and has a distinctive odor. It is important to note that Type F fluid is not compatible with other types of ATF, such as Dexron or Mercon, and should not be mixed with them. When servicing a vehicle that requires Type F fluid, it is essential to use the correct fluid specified by the manufacturer.
Conclusion
In summary, Type F transmission fluid is a specialized automatic transmission fluid developed by Ford for use in certain Ford, Lincoln, and Mazda vehicles. It is formulated to provide the specific properties and performance characteristics required by these transmissions. Proper identification and use of Type F fluid is crucial for the long-term health and operation of the transmission.
What does type F transmission fluid mean?
Ford first produced its own ATF in 1967 and referred to as Type F. The name comes from Ford's specification number for the fluid, ESW M2C33-F. This fluid was used in all Ford transmissions until 1977 and most Ford transmissions until 1980. In the late '80s, we saw the introduction of Dexron-III/Mercon.
Is type F the same as Dexron?
The main difference is that Type F has no friction modifiers while Dexron fluids do. This means Type F creates firmer shifts, making it suitable for older Ford and some import vehicles, while Dexron fluids provide softer shifts and are used in most modern GM and Ford vehicles. Using the wrong fluid can cause shifting problems, so always check your vehicle's manual.

Type F transmission fluid
- Friction: Does not have friction modifiers, resulting in firm, mechanical shifts.
- Applications: Originally used in older Ford vehicles (pre-1980s) and some imports requiring this specific fluid, which often used bronze clutches.
- Characteristics: Designed for quick clutch engagement and to prevent slippage.
Dexron transmission fluid
- Friction: Includes friction modifiers, which create a softer, smoother shifting experience.
- Applications: Most common in modern GM and Ford vehicles, and many other applications as a general automatic transmission fluid.
- Characteristics: Designed to provide smooth engagement and meet modern transmission specifications.
Which to use
- Always use the fluid specified in your vehicle's owner's manual: to avoid damage and shifting issues.
- If your car requires Type F, using Dexron can cause problems.
- If your car requires Dexron, using Type F is generally not recommended, though it may create firmer shifts and is sometimes used in performance applications for specific results.
Are type F and ATF the same?
No, Type F is not the same as all ATF, though it is a specific type of automatic transmission fluid. Type F ATF is an older fluid that lacks modern friction modifiers, resulting in a more mechanical and rigid shift, and is designed for older Ford and select import transmissions, primarily those made before 1980. Modern ATFs have different formulations and should not be substituted for Type F in older vehicles unless the manufacturer's manual specifies otherwise.
Type F vs. modern ATF
| Feature | Type F ATF | Modern ATF (e.g., Mercon, Dexron) |
|---|---|---|
| Friction Modifiers | Lacks friction modifiers, leading to a more mechanical and abrupt shift. | Contains friction modifiers for smoother gear engagement and reduced wear. |
| Vehicle Application | Primarily for older Ford, Lincoln, Mercury, and some import vehicles, typically pre-1980. | For modern vehicles, and includes specific formulations like Mercon for newer Ford vehicles. |
| Performance | Designed for high-friction, non-slipping clutch engagement. | Engineered to protect modern transmissions and provide long fluid life. |
| Compatibility | May cause damage to transmissions that require modern ATFs due to the lack of friction modifiers and different additive packages. | Can be incompatible with older transmissions, potentially causing issues like leaks or excessive wear. |
