SHIFT SOLENOID E OUTLINE [SJ6A-EL]

EHU051321101102

•

Shift solenoid E is directly equipped to the control valve body component.

•

Shift solenoid E turns on and off according to the control signals from the TCM, and switches the C4 clutch and
the B1 brake.

SHIFT CONTROL OUTLINE [SJ6A-EL]

EHU051318901106

•

Based on the shift diagram, shift solenoids A, B, C, D, E, F, and G are controlled according to the vehicle speed
and the throttle opening angle, and the shift control of the transmission is performed.

•

When certain conditions are met, the TCM selects a shift mode suitable to the driving conditions and
automatically switches to the mode to perform smooth shifting.

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.
