Signature Series Ultra-Low Viscosity Automatic Transmission Fluid

AMSOIL Signature Series Ultra-Low- Viscosity 100% Synthetic ATF (ULV) is designed specifically for transmissions requiring FORD MERCON* ULV and GM DEXRON* ULV specifications and will now be the primary recommendation for these applications.

The Ford* and GM* 10-speed transmission has improved power and performance in trucks, SUVs and high-performance cars since its inception. These units must manage ever-higher horsepower, payload and towing capacities, which create additional heat and pressure inside the transmission.

Elevated temperatures cause fluids to break down, allowing damaging metal-to-metal contact and the formation of sludge and varnish deposits. The problem is amplified in transmissions with more gears, clutch packs and narrow oil passages that require clean, high-quality fluid to achieve maximum performance and life.

Reserve Protection

AMSOIL Signature Series ULV 100% Synthetic Automatic Transmission Fluid is engineered to withstand extreme heat and pressure to resist shear. It contains friction modifiers for smooth, reliable shifts, a boosted dose of antioxidants to defend against heat and strong protection against sludge and varnish deposits that can clog narrow passages and contribute to clutch glazing. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use and abuse.

Protection from Wear

Varying speeds and loads cause torque multiplication and extreme stress on gears and bearings. Signature Series ULV ATF is formulated with high film strength and premium anti-wear/ extreme-pressure additives to help prevent wear during severe service.
