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.
