The E4OD transmission is controlled by the Powertrain Control Module i.e. "the computer."
The principal (but not the only) inputs it reads for control are: engine RPM, throttle position, vehicle speed and transmission range.
The stock program for the E4OD tends to not call for part-throttle downshifts. Unless the Throttle Position Sensor reads at or near WOT (wide open throttle) the tranny will usually remain in 3rd or 4th
