Transmission and Torque Converter
(ZF 4WG-310)
TRANSMISSION AND TORQUE CONVERTER
The machine contains a powershift transmission that has four forward speeds and three speeds in
reverse. Gear changes are made by an elector-hydraulic control valve that is mounted on transmission.
Moving gear select lever in cab, generates an electrical signal that is transmitted to the control valve. The
control valve contains proportional valves that direct pressurized fluid to various clutches that control the
forward and reverse gears.
