When was the last fluid and filter change? could be a problem with a shifting solenoid. The computer uses the signal from the throttle position and vehicle speed sensors as throttle and governor pressures. and the coolant temperature sensor to control the overdrive-Could also be a problem within the valve body-

When all these sensors are operating properly -have the transmission pressure tested.
