My 2005 MCS has the 6 speed automatic and yesterday the car shifted from 3 to 4 and nothing by motor revs. Pulled over and turn the car off and when I restarted the car flashed the EP code. The car would not go in any gear but when I press the gas pedal the car would move slowly. The day the car would drive in 1,2&3 gears and then 4th and nothing by motor revs. I disconnected the battery for 12 hrs and when I reconnected it the EP code was still there. I still only have 3 forward gears but the car will go to about 50 mph. If I reset the computer with a ode code reader is there any chance the transmission will go back to normal or does it need a new valve body. I need advise
