Cruise control ECU delivers an input signal to control overdrive operation in accordance with vehicle speed when cruise control is operating. When in overdrive with cruise control on, if vehicle speed drops 10 MPH less than set speed, overdrive is released to prevent reduction in vehicle speed. Once vehicle speed is more than set speed, overdrive is resumed. Cruise control ECU is located behind instrument panel on driver's side of vehicle.
