P28EDElectric/Auxiliary Transmission Fluid Pump B Overspeed

P28ED indicates that the transmission control module has detected an overspeed condition in the electric auxiliary transmission fluid pump 'B' circuit, meaning the pump motor is spinning faster than its commanded or expected speed. The computer compares pump speed sensor data against the desired speed for the current operating conditions and sets this code when the actual speed exceeds the threshold.
