TM-182 < SYSTEM DESCRIPTION > [CVT: RE0F10B] SYSTEM • The lock-up applied gear range was expanded by locking up the torque converter at a lower vehicle speed than conventional A/T models. • If the CVT fluid temperature is low or the vehicle is in fail-safe mode due to malfunction, lock-up control is prohibited. TORQUE CONVERTER CLUTCH AND SELECT CONTROL VALVE CONTROL Lock-up Released In the lock-up released state, the torque converter clutch control valve is set into the unlocked state by the torque converter clutch solenoid valve and the lock-up apply pressure is drained. In this way, the torque converter clutch piston is not coupled. Lock-up Applied In the lock-up applied state, the torque converter clutch control valve is set into the locked state by the torque converter clutch solenoid valve and lock-up apply pressure is generated. In this way, the torque converter clutch piston is pressed and coupled. Select Control When shifting between “N” (“P”) ⇒“D” (“R”), optimize the operating pressure on the basis of the throttle posi- tion, the engine speed, and the secondary pulley (output) revolution speed to lessen the shift shock. SHIFT CONTROL SYSTEM INFOID:0000000012200891 NOTE: The gear ratio is set for each position separately. SHIFT CONTROL SYSTEM : System Description INFOID:0000000012200892 • To select the gear ratio that can give the driving force to meet driver's intent or vehicle situation, the vehicle driving condition such as vehicle speed or accelerator pedal position is detected and the most appropriate gear ratio is selected and the shifting method before reaching the speed is determined.
