Adaptive Gearshift Control

Stop and Go Function

When the transmission control module detects that the vehicle is being driven in a traffic jam situation (many stops and starts at very low road speed), it will begin using second gear when pulling away. Starting in second gear and not shifting down to first gear when stopping eliminates the feeling of excessive load reversals; providing a more comfortable driving style in this situation.

Recognition of Deceleration Rate

Typically, automatic transmission drive programs will upshift to the highest gear possible at a given road speed with no throttle application. The transmission control module on the A5S 560Z monitors the rate of change in throttle position when the throttle is released. If the throttle is released quickly, the transmission will stay in the gear presently engaged in anticipation of the driver's intent to slow down. If the throttle is gradually backed-off, as when approaching the desired road speed, the transmission will upshift to the highest possible gear for that road speed.
