My 93 Lincoln Towncar is showing trouble codes in the transmission # 621 Shift Solenoid 1 circuit failure, and code # 622 Shift Solenoid 2 circuit failure, and code # 624 Electronic Pressure Control (EPC) circuit failure and code # 652 Torque Convertor Clutch (TCC) solenoid circuit failure, is it possible for all thes components to go bad at once or do thes codes point back to one component causing the trouble, most of the time the Overdrive light flashes, any information will be greatly appreciated, thanks Dan

First thing you want to do is, check the level of the transmission fluid (when its warm and running) and see if thats okay. And the primary thing you want to check is to see if the main transmission wiring harness is still plugged in/or not and if its damaged at all. Check that first because if that harness is unplugged then it will set those EXACT same codes. (The main trans wiring harness is located on the drivers side of the transmission just right above the pan)
