Not sure if this is the right area. But have to g6 that is just got for my wife. The day we got it it popped p0751 for shift solenoid 1-2 so we replaced it. Got it all together but now it all gears are forward. Park, neutral, drive is all forward. It has the manual option and on the dash when you pull it out of park it shows m1. I have tried to reset the computer by unhooking the batt for 30 plus minutes and didnt change it. If I unhook the shift lever with the car off it will shift into neutral. Anyone have any ideas on what went wrong?
