I have a 2001 oldsmobile aurora 4.0. Yesterday i was driving and i noticed my aurora would not shift into 4th gear and all the other gears were delayed when shifting. I hooked my code reader up and it pulled codes for 1-2 shift solenoid 2-3 shift solenood input shaft solenoid torque convertor clutch solenoid and multiple other codes for transmission. How would that many solenoids al ln of a sudden go bad? Does this sound like a wiring harness to anyone else? Or could transmission of overheated and caused failure of everything inside?
