Function
Torque converter
The torque converter is the device that increases the engine
torque as well as the conventional A/T and transmits it to the tran-
saxle.
Oil pump
It is a parachoid type oil pump with the flow control valve directly
controlled by the engine. Discharged oil from oil pump is transmit-
ted to the control valve. It is used as the oil of primary and second-
ary 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 for-
ward/backward movement.
Forward clucth
Reverse brake
Primary pulley
It is composed of a pair of pulleys (the groove width is changed
freely in the axial direction) and the steel belt (the steel star wheels
are placed continuously and the belt is guided 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 over-
drive status continuously with non-step. It is controlled with the oil
pressures of primary pulley and secondary pulley.
Secondary pulley
Steel belt
Output gear
The drive power from the secondary pulley returns the decelera-
tion gears [primary deceleration (output gear/idler gear pair) and
secondary deceleration (reduction gear/final gear pair)]. It is trans-
mitted from differential to drive wheel.

Manual shaft
The parking rod rotates the parking pole and the parking pole en-
gages with the parking gear when the manual shaft is in P position.
As a result the parking gear and the output axis are fixed.
