Product Highlights View Full Description

Formulated for heavy-duty powershift transmissions. Provides outstanding friction performance for enhanced clutch engagement. Prevents slippage and glazing. Shear stable and anti-wear fortified. Resists high-temperature oxidation, varnish & sludge formation. Superb cold-flow properties.

AMSOIL Synthetic Powershift Transmission Fluids are specifically designed for high-torque heavy-duty powershift transmissions. Formulated for extended drain intervals, Powershift Transmission Fluids contain top-quality synthetic base stocks and a high level of top-quality additives selected specifically for powershift transmissions. They offer exceptional transmission friction performance, smooth brake operation, gear and bearing wear protection and increased equipment life.

Friction Characteristics
AMSOIL Synthetic Powershift Transmission Fluids are compatible with common metallic and non-metallic friction materials. Their stable frictional characteristics help eliminate excessive brake noise and vibration. Their non-slip friction properties are designed to prevent clutch slippage, which can cause glazing or friction surface deposits and material degradation. Powershift Transmission Fluids are formulated to deliver responsive yet smooth clutch engagements, excellent power transmission through clutches and synchronizers and superior hydraulic fluid performance for servo-equipped units.

Wear Protection
AMSOIL Synthetic Powershift Transmission Fluids meet the wear requirements of the Caterpillar TO-4 specification and are formulated for superior shear stability. This superior shear stability allows Powershift Transmission Fluids to maintain grade throughout service life, providing long-term protection against equipment wear, even when equipment is frequently subjected to sustained periods of applied pressure or high horsepower and high torque.

Superior High- and Low-Temperature Performance
In high temperatures, AMSOIL Synthetic Powershift Transmission Fluids effectively protect components from wear. Their superior oxidative and thermal stability inhibits the formation of varnish, deposits and sludge so equipment runs clean. Synthetic Powershift Transmission Fluids function as heat transfer fluids and help cool hot running equipment. In low temperatures, Synthetic Powershift Transmission Fluids flow readily for dependable startup and post-startup protection.

Copper Corrosion, Rust and Foam Inhibition
AMSOIL Synthetic Powershift Transmission Fluids protect equipment from copper corrosion and rust, even during equipment storage. Synthetic Powershift Transmission Fluids do not foam in service, protecting equipment from metal-to-metal contact and wear.
