Got in to move the car, turned the key and wouln't start. No noise except a slight click but nothing like the starter motor is trying to engage, or anything like that. So, maybe a coincidence that this happened about 10 days after replacement of the transmission, so obvious things to check are the solenoid and the ignition switch. But there must be some sensor that tells the system that the car is in park or neutral so it's OK to start. I ran my code checker, but none came up for transmission or ECM. So, I guess I check the starter/solenoid by jumping the electrical at the starter/solenoid. If that starts the car, is it safe to assume it is the ignition switch? Or should I look elsewhere and if so, where? Thanks for the help guys!
