SYSTEM
DESCRIPTION
Based on accelerator pedal angle, engine speed, prim
ary pulley speed, and the input speed, the optimum
operating pressure is set to reduce impact of a selector lever operation while shifting from “N” (“P”) to “D” (“R”)
position.

DESCRIPTION
• Controls for improvement of the transmission effici ency by engaging the torque converter clutch in the
torque converter and eliminating slip of the converter. Achieves comfortable driving with slip control of the
torque converter clutch.
• The oil pressure feed circuit for the torque converter clutch piston chamber is connected to the torque con-
verter clutch control valve. The torque converter clut ch control valve is switched by the torque converter
clutch solenoid valve with the signal from TCM. This contro ls the oil pressure circuit, which is supplied to the
torque converter clutch piston chamber, to the release side or engagement side.
• If the CVT fluid temperature is low or the vehicle is in fail-safe mode due to malfunction, lock-up control is
prohibited.
Lock-up engagement
In lock-up engagement, the torque converter clutch solenoi d valve makes the torque converter clutch control
valve locked up to generate the lock-up apply pressure. This pushes the torque converter clutch piston for
engagement.
Lock-up release condition
In lock-up release, the torque converter clutch solenoi d valve makes the torque converter clutch control valve
non-locked up to drain the lock-up apply pressure. This does not engage the torque converter clutch piston.

Reference ValueINFOID:0000000009464218
CONSULT DATA MONITOR STANDARD VALUE
• In CONSULT, electric shift timing or lock-up timing, i. e. operation timing of each solenoid valve, is displayed.
Therefore, if there is an obvious difference between t he shift timing estimated from a shift shock (or engine
speed variations) and that shown on the CONSULT, the mechanism parts (including the hydraulic circuit)
excluding the solenoids and sensors may be malfunctioning. In this case, check the mechanical parts follow-
ing the appropriate diagnosis procedure.
• Shift point (gear position) displayed on CONSULT slight ly differs from shift pattern described in Service Man-
ual. This is due to the following reasons.
- Actual shift pattern may vary slightly within specified tolerances.
- While shift pattern described in Service Manual indica tes start of each shift, CONSULT shows gear position
at end of shift.
- The solenoid display (ON/OFF) on CONSULT is changed at the start of gear shifting. In contrast, the gear
position display is changed at the time when gear shif ting calculated in the control unit is completed.

Control
When a wheel spin is detected, the engine output and gear ratio are limited and the line pressure is increased.
Limits engine output when a wheel spin occurs in any of right and left drive wheels.
Vehicle behavior in
control If the accelerator is kept depressing during wheel spin, the engine revolution and vehicle speed are limited to
a certain degree.
Normal return condi-
tion Wheel spin convergence returns the control to the normal control.
Control Engine output is controlled according to a vehicle speed while reversing the vehicle.
Vehicle behavior in
control Power performance may be lowered while reversing the vehicle.
Normal return condi-
tion Torque returns to normal by positioning the sele
ctor lever in a range other than “R” position.
