1.0 General Information On Automatic Transmission Fluids
Automatic Transmission Fluid was developed especially for automatic transmissions. It requires additives which are carefully matched with each other, a high viscosity index and a solidification point below -40°F/-40°C.
Friction behavior of Automatic Transmission Fluid in plate-type clutches under very different operating conditions is extremely important. Other important factors are:
- Wear Protection
- Oil Film Shear Resistance
- Adhesive Property
- Oxidation Resistance
- Corrosion Inhibition
- Sludge Prevention
- Temperature-Dependent Viscosity Changes
- Compatibility With Sealing Materials
