A/T Overdrive Control during Cruise Control Driving

When the vehicle speed is approximately 3 km/h (2 MPH) below set speed, a signal is sent

When this occurs, the TCM (transmission control module) cancels overdrive.

After vehicle speed is approximately 1 km/h (0.6 MPH) above set speed, overdrive is reactivated.
