Function

Torque converter

The torque converter is the device that increases the engine torque as well as the con-
ventional A/T and transmits it to the transaxle.

Oil pump

The efficiency of pump discharge rate at low-rpm and the optimization at high-rpm have
been increased through the oil pump drive chain by adopting a vane-type oil pump con-
trolled by the engine. Discharged oil from oil pump is transmitted to the control valve. It
is used as the oil of primary and secondary pulley operation and the oil of clutch operation
and the lubricant for each part.

Planetary gear

Perform the transmission of drive power and the switching of forward/backward move-
ment.

Forward clutch

Reverse brake

Primary pulley

It is composed of a pair of pulleys (the groove width is changed freely in the axial direc-
tion) and the steel belt (the steel star wheels are placed continuously and the belt is guid-
ed with the multilayer steel rings on both sides). The groove width changes according to
wrapping radius of steel belt and pulley from low status to overdrive status continuously
with non-step. It is controlled with the oil pressures of primary pulley and secondary pul-
ley.

Secondary pulley

Steel belt

Output gear

The drive power from the secondary pulley returns the deceleration gears [primary de-
celeration (output gear/idler gear pair) and secondary deceleration (reduction gear/final
gear pair)]. It is transmitted from differential to drive wheel.

Instruction shaft

The parking rod rotates the parking pole and the parking pole engages with the parking
gear when the instruction shaft is in P position. As a result the parking gear and the output
axis are fixed.
