COMPONENTS DESCRIPTION CHART
| Item | Function |
|---|---|
| Torque converter | The torque converter is the device that increases the engine torque as well as the conventional AT and transmits it to the transaxle. |
| Oil pump | The efficiency of pump discharge rate has been increased at low-rpm and optimized at high-rpm by adopting a vane-type oil pump controlled 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 movement. |
| Forward clutch | |
| 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 overdrive status continuously with non-step. It is controlled with the oil pressures of primary pulley and secondary pulley. |
| Secondary pulley | |
| Steel belt | |
| Output gear | Variable speed gear consists of primary deceleration (output gear and idler gear in pair), secondary deceleration (reduction gear and final gear in pair), and acceleration (drive trans gear and ring trans gear in pair). Each of them uses a helical gear. |
| Idler gear | |
| Reduction gear | |
| Final gear | |
| Differential | |
| Drive trans gear | |
| Ring trans gear | |
| Manual shaft | The parking rod rotates the parking pole and the parking pole engages with the parking gear when the manual shaft is in P position. As a result the parking gear and the output axis are fixed. |
| Parking rod | |
| Parking pawl | |
