It can be caused by dirty fluid, a bad pressure solenoid, open or shorted wiring to that solenoid, a faulty control valve assembly, a corroded or damaged harness connector, a restriction in a hydraulic circuit, a failing transmission oil pump and/or a faulty TCM. If the fluid is clean, the most likely cause would be the transmission solenoid pack which is attached to the valve body, but one would have to follow the diagnostic steps for this code located in the factory service manual to be sure.
