Torque Converter
The torque converter is used to keep stable start, reduce torsional vibration of transmission system and
prevent overload of the transmission system.
The torque converter could ensure stable start and even
acceleration of the vehicle. The hydraulic vibration
absorption could eliminate or reduce the impact and
dynamic load in the transmission system, extending the
service life of the components of the engine and
transmission system.
Transmission Control Unit (TCU)
The transmission control unit (TCU) is installed on the
battery tray. It receives input signals of switches and sensors
18
and mainly controls the operation of the gear shifting and
locking solenoid. Transmission gears are regulated by the
electronic gear shift system. The TCU processes the input
signals and regulates transmission hydraulic system by
exploiting the information received.
