AWF21 and TF80-SC transmissions

The unique formulation of Aisin fluid is designed to provide excellent lubrication of transmissions in specified Aisin AW slip-controlled lock-up automatic transmissions. These outstanding performance capabilities translate into significant operational benefits, including:

Excellent lubricating characteristics for quiet operation and smooth shifting in approved transmissions.
Controlled friction properties for smooth and efficient transmission of power across all normal temperature ranges.
Helps to control transmission shudder and provide excellent vehicle driveability.
Helps to extend transmission life based on excellent wear control.
Long fluid life based on excellent oxidation resistance.
Excellent viscosity stability (high viscosity index) to help assure adequate lubrication without excessive thinning in severe high-temperature service or thickening at low starting temperatures.
Resistance to foaming.
Superb protection against rusting and corrosion.
Compatibility with transmission seal materials.

Our recommendation on replacement (flushing) is to use the colour of the fluid as the indicator. Light pinkish brown to light golden brown OK to leave it. Once the fluid is brown to blackish-brown it is time to replace. (Volvo only recommends replacement on towing service at 52,500 miles (84,000 kilometres)).

Note: This is not synthetic fluid, it is conventional ATF with an anti-foaming agent additives.
