| Control items | Description of control | ||
|---|---|---|---|
| Transmission control | Shifting control | Base shift control
|
Upshifting and downshifting are set for each range, gear and pattern according to throttle position and vehicle speed. |
| ABS-in-operation control | Gear is shifted in accordance with vehicle speed when ABS signal is input. | ||
| ATF low temperature control | Shifting into 4th gear is prevented when ATF temperature is below the preset value. | ||
| Automatic pattern select control | POWER pattern control | POWER pattern is selected when the accelerator pedal position exceeds a preset opening. | |
| BASE pattern control | When the accelerator pedal position becomes lower than the preset value, BASE pattern is resumed. | ||
| Lockup control | Base lockup control | Lockup ON is set for D-range 4th gear; ON/OFF is set for all gears (except D-range 4th) and patterns. Lockup control is performed according to throttle position and vehicle speed. (Basically lockup is OFF during gear shifting.) | |
| Line pressure control | Ordinary control | Line pressure is regulated according to throttle position, vehicle speed and range signals. | |
| Shift timing control | Gear speed control | Controls duty of duty solenoids. | |
| Lockup control | When shifting, the lockup clutch is temporarily released. | ||
| AWD multi-plate clutch (LSD) control | Ordinary transfer control | Multi-plate clutch (LSD) pressure is regulated according to the torque input to the transfer and the driving condition. | |
| Start control | When starting, the LSD pressure is adjusted proportionately to the throttle value angle. | ||
| Turning control | When the front and rear wheel speed ratio is less than the set value for a vehicle speed, the LSD pressure is decreased. | ||
| Slip control | When a front or rear wheel starts slipping, the LSD pressure is increased. | ||
| ABS-in-operation control | The LSD pressure is adjusted to the set level immediately after reception of ABS signal. | ||
| Base brake control | When the brake switch is ON and throttle valve is fully closed, the LSD pressure is lowered. | ||
| 1 range control | The LSD pressure is increased to improve driveability. | ||
