•
Slip control, by sliding the TCC piston when TCC is in the OFF range, extends the TCC range to low vehicle
speeds. This suppresses a rise in engine speed and increases transmission efficiency, improving fuel economy.
At the same time, through the sliding of the TCC piston, engine vibration can be absorbed by the torque
converter. (However, this assumes that ATF JWS3309 is used.)

•
When shifting between N-D and N-R, and when the transmission shifts between 1-6, the TCM outputs an
engine torque request signal to the PCM, thereby cutting the inertia torque increase caused by shifting in order
to provide smooth shifting characteristics.
•
Furthermore, clutch-to-clutch control performs engine torque control to ensure that engine output does not
exceed the proscribed upper limit even when the accelerator pedal is depressed suddenly in order to prevent
air blasts from the engine (due to torque interruption) when shifting.

Control Description
TCC control
•
Control is performed using a TCC control solenoid. The TCC control solenoid is linearly
turned ON and OFF, the TCC clutch inside the torque converter is operated, and the
pump impeller and turbine runner are connected. Through this, the engine and the
automatic transaxle are coupled and engine output is connected directly to the
automatic transaxle, eliminating transmission loss and enhancing fuel economy.
Slip control
•
Control is performed using a TCC control solenoid. The TCC control solenoid is linearly
turned ON and OFF and the TCC piston within the torque converter is operated outside
of the TCC range. The TCC piston slides without being in a completely coupled
condition, increasing transmission efficiency and enhancing fuel economy. However,
because the sliding of the TCC piston places a load on the ATF, it is assumed that ATF
JWS3309 is used.
