NOTE:

The gear ratio is set for every position separately.

System Description

INFOID:0000000004201653

In order to select the gear ratio which can obtain the driving force in accordance with driver's intention and the

vehicle condition, TCM monitors the driving conditions, such as the vehicle speed and the throttle position and

selects the optimum gear ratio, and determines the gear change steps to the gear ratio. Then send the com-

mand to the step motor, and control the flow-in/flow-out of line pressure from the primary pulley to determine

the position of the moving-pulley and control the gear ratio.

“D” POSITION

Shifting over all the ranges of gear ratios from the lowest to the high-

est.

“M” POSITION

When the selector lever is put in the instruction shift gate side, the fixed

changing gear line is set. By moving the selector lever to + side or -

side, the instruction mode switch is changed over, and shift change like

M/T becomes possible following the changing gear set line step by

step.

DOWNHILL ENGINE BRAKE CONTROL (AUTO ENGINE BRAKE CONTROL)

When downhill is detected with the accelerator pedal released, the engine brake will be strengthened up by

downshifting so as not to accelerate the vehicle more than necessary.
