NOTE:
The gear ratio is set for each position separately.

System Description

INFOID:0000000003806367

In order to select the gear ratio that 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 TCM sends the
command to the step motor, controls the inflow/outflow of line pressure from the primary pulley to determine
the position of the moving-pulley and controls the gear ratio.

“D” POSITION

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

SPORT MODE

Use this position for the improved engine braking.

“L” POSITION 

By limiting gear range to the lowest position, the strong driving force
and the engine brake can be secured.

DOWNHILL ENGINE BRAKE CONTROL (AUTO ENGINE BRAKE CONTROL)

When a downhill slope 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.

SHIFT CONTROL SYSTEM

ACCELERATION CONTROL

According to vehicle speed and a change of accelerator pedal angle, driver's request for acceleration and driv-
ing scene are judged.   This function assists improvement in the acceleration feeling by making the engine
speed proportionate to the vehicle speed. And a shift map that can gain a larger driving force is available for
compatibility of mileage with driveability.
