I am trying to find out some information on my cruze. My transmission went out on my car and i have a salvage transmission out of the same make and model vehicle. I would like to know it the TCU / TCM needs to be programmed if it came out of the same make and model? Also, where is the TCU / TCM located on this vehicle? I think it is right next to the ECM in the engine compartment but i want to confirm a few things before going under way with replacement of the transmission. Thank you guys!
