AT-36
A/T CONTROL SYSTEM
Revision: 2007 April2007 M35/M45
Shift Change System Diagram
ASC (ADOPTIVE SHIFT CONTROL)
ASC automatically shifts or hold at the 3rd or 4th gear on certain roads (up/down slope and curve) and driving
condition.
When Driving on an Up/Down Slope

ASC judges up/down slope according to the angle of accelerator pedal and vehicle speed. Holding gear at
the 3rd or 4th on an up-slope prevents shift hunting and controls the vehicle to gain maximum driving
force. On a down-slope, automatic shift-down to the 3rd or 4th gear controls to gain maximum engine
brake.
When Driving on a Curve

TCM receives side G sensor signal from ABS actuator and electric unit (control unit). Holding gear at the
3rd or 4th based on the signal prevents shift-up and kick-down and controls to drive smoothly.
