•
The AW6A (X) -EL automatic transaxle does not have a driving mode selection switch that allows drivers to
select a mode themselves. The vehicle is ordinarily in NORMAL mode. However, when specific conditions are
met, the TCM selects a shifting pattern appropriate to driving conditions from all of the shifting patterns and
switches automatically.
Active Adaptive Shift (AAS) Mode
•
When certain conditions are met, AAS mode is automatically selected from normal mode. In AAS mode, the
shift point is set higher than the normal shift point so that high-engine speed, high-output conditions are
available.
•
AAS mode is canceled when the vehicle speed remains constant (stable vehicle behavior).
Conditions for switching to active adaptive shift (AAS) mode
•
The accelerator pedal is depressed fully to accelerate rapidly while driving in D range.
•
Rapid acceleration or deceleration continues for a certain period of time while driving in D range.
Mode Description
NORMAL
•
Used during normal driving.
AAS
•
In this mode, shift point and TCC point settings are higher than in the normal driving condition for
generating high engine speed and output.
MANUAL (See 05-17-35 MANUAL MODE SHIFT CONTROL OUTLINE [AW6A-EL, AW6AX-EL].)
HIGH TEMP
•
When ATF temperature becomes too high, this mode activates TCC at an earlier timing to stop
the temperature rise and lower the temperature.
CRUISE CONTROL
•
When cruise control is ON, gears are fixed to perform smooth driving.
DOWN-SLOPE
•
When the vehicle is driven down a slope, the TCM detects the gradient based on the signal from
the PCM and the engine speed, and switches the drive mode to DOWN-SLOPE mode. Due to
this, load on the brakes is reduced.
UP-SLOPE
•
When driving up a slope, TCM detects an up-slope based on the engine control unit signal and
output speed. TCM switches to UP-SLOPE mode to prevent driving force drop.
COLD
•
TCM detects that the engine is cold based on the signal (ECT signal) from the PCM when the
ignition switch is on. TCM switches to cold mode to improve warm-up performance.
