PRODUCT DESCRIPTION
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 unmatched transmission
friction performance, smooth brake operation, reduced gear and bearing wear and increased
equipment life.

Friction Characteristics
AMSOIL Synthetic Powershift Transmission Fluids are compatible with common metallic and
nonmetallic friction materials. Their stable frictional characteristics eliminate excessive brake noise
and vibration. Their nonslip friction durability virtually eliminates 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 exceed the wear requirements of the Caterpillar
TO-4 specification and are formulated without viscosity index improvers for superior shear stability.
The superior shear stability of Powershift Transmission Fluids allows them 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.

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
are excellent heat transfer fluids and may help hot-running equipment operate cooler and run in its
optimal temperature range. 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 the metal-to-metal contact and wear that occurs with use of
foam-filled fluids.

AMSOIL Synthetic 10W Powershift Transmission Fluid can be used in Caterpillar, Allison, Komatsu,
Clark, Hurth, Borg-Warner, Twin Disc, Voith, ZF, Funk and Brockhouse powershift-type
transmissions and Eaton/Rockwell/Fuller transmissions.

Installation
AMSOIL Synthetic Powershift Transmission Fluids are fully compatible with other TO-4 fluids used
in powershift applications. To install AMSOIL Synthetic Powershift Transmission Fluids, drain the
fluid in the system, replace the filter (if so equipped) and install the appropriate Powershift
Transmission Fluid.

Service Life
AMSOIL Synthetic Powershift Transmission Fluids provide extended service life beyond
conventional petroleum fluids if Synthetic Powershift Transmission Fluids are kept free of dirt and
moisture. Oil analysis is recommended if extending service intervals beyond equipment
manufacturer recommendations.

AMSOIL Synthetic Powershift Transmission Fluids may be used for 250,000 miles or two years
(whichever comes first) in CD-50 manual transmission applications.
