PLEASE CHECK TO make sure your auto trans can be operated with the car off. If it cannot you will eventually damage the transmission because fluid is not circulating while the car is off. One way some have suggested checking is by researching online or in the owners manual as to whether you car can be flat towed, which, they say, would mean it can run EOC too. But I would not know. The safest bet with an auto trans is always to keep the enine on and coast in neutral or in gear. Good luck!
