Twin Clutch-Sportronic Shift Transmission (TC-SST)

GENERAL INFORMATION

TWIN CLUTCH-SPORTRONIC SHIFT TRANSMISSION (TC-SST)

Due to the addition of RALLIART, TC-SST (twin clutch-sportronic shift transmission) has been adopted. The TC-SST assembly is a twin clutch type automatic M/T that offers the easy driving similar to A/T, excellent sport driving, and enhanced fun to drive.
The TC-SST assembly offers the following features.
Good fuel efficiency

- Because the basic structure is the same as M/T, it is simple and has a high driving force transmission efficiency.
- Instead of the torque converter, the clutch is used to transfer the driving force from engine, reducing the loss of driving force.
- Through the precise joint control with the engine, the gears can be shifted at the optimum timing. (With NORMAL mode)
Shift feeling

- Corresponding to the optimization of shift change timing by the automatic shifting, the shift shock is reduced, and the shifting is made smooth without torque loss.
Easy drive

- By adopting TC-SST-ECU, solenoid valve, sensor, valve body, and others, the easy driving similar to A/T has been achieved.
Sport drive

- Drive mode switching function is equipped which enables the selection of NORMAL, SPORT.
Fun to Drive

- The manual mode and the paddle shift are adopted that allow the driver to shift gears at any timing.
Starting acceleration

- The clutch and gear shift operation are automatically controlled, reducing the power transfer loss and achieving the ideal starting acceleration.
