Product Highlights

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.

Helps Prevent Clutch Slippage

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

Excellent Wear Protection

AMSOIL Synthetic Powershift Transmission Fluid meets the wear and frictional requirements of the Caterpillar* TO-4 specification and is formulated for superior shear stability. Its superior shear stability allows Powershift Transmission Fluid to stay in grade throughout its service life, providing long-term protection against equipment wear, even when equipment is frequently subjected to sustained high torque.

Superior High- and Low-Temperature Performance

In high temperatures, AMSOIL Synthetic Powershift Transmission Fluid effectively protects components from wear. Its superior oxidative and thermal stability inhibits the formation of varnish, deposits and sludge so equipment runs clean. Synthetic Powershift Transmission Fluid functions as a heat-transfer fluid and helps cool hot-running equipment. In low temperatures, Synthetic Powershift Transmission Fluid flows readily for dependable startup and post-startup protection.

Copper Corrosion, Rust and Foam Inhibition

AMSOIL Synthetic Powershift Transmission Fluid protects equipment from copper corrosion and rust, even during equipment storage. It does not foam in service, protecting equipment from metal-to-metal contact and wear.
