    your o/d operates from at least three inputs from the sensors to the pcm. one- coolant temperature sensor, the coolant temperature has to be at least 180 degrees, two- the throttle opening should be at least 30%, and three-the vehicle speed must be around 35 mph. when the three parameters have been met, the transmission goes into o/d. if one of the minimum value is missing- no overdrive. if the engine is running in limp mode, meaning the vehicle is in basic mode just to get to a service shop, o/d is cancelled until the problem had been addressed
