Description
The engine output torque is transferred to the transmission via the torque converter. The converter has a fixed stator. The
stator multiplies the torque. The multiplication is at its greatest when the engine is running at high speed and the turbine
rotor is stationary, e.g. when starting the machine. The torque from the torque converter passes through the transmission
and dropbox to the drive axles. In the differential gear the torque is divided out to the planetary hub gears and the wheels.
The transmission has four speed gears and two directional gears.
