Slope is recognized based on engine RPM and accelerator pedal position.
→
Delays up shift
Ignition timing is delayed to reduce torque at all shifting moments.
→
Improves shift quality
Engine rpm is limited until the gears are fully engaged when shifting from “N” to “D”.
→
Prevents shift shock
When the ESP is controlling the engine torque, shifting is not available and vehicle
starts off with 2nd gear.
→
Cannot use kick-down function and shift at maximum rpm
Brake control is not affected.
It is not shifted up when accelerator pedal is abruptly released.
→
To get engine brake effect during cornering
As altitude increases (atmospheric pressure reduces), engine torque decreases. To
compensate this torque reduction, shift up occurs when depressing the accelerator
pedal more than usual operation (adjusting shift diagram).
→
Improves driving performance and increases torque
If transmission fluid temperature is too low, the shifting point gets delayed in full throttle
and kick down.
→
Improves driving performance
When starting the engine with cycling the ignition switch (“OFF” and “ON”) due to
transmission trouble, the selector lever should be placed in “P” position. If starting
the engine with selector lever “N” position, the lever should be moved into “P” position.
The selector valve changes the path of hydraulic pressure in selector lever “P” position.
→
The hydraulic pressure flows to direct operation mode via “R” and “D”
valve to operate “reverse 2nd” and “forward 2nd” gear.
Function to optimize the shifting quality.
→
Compensates the shifting quality according to play and wear
