Well, an automatic can be jump started, but heres the thing, unless you live at the top of a really steep hill and can hit 30 mph + without hitting anything else or having to stop suddenly without power to the brakes, it is seriously not recommended !
on an automatic, unlike a manual, a flat battery can be recharged from a mains socket. Simply connect a figure-8 mains lead (often used for a laptop or similar) to the flux capacitor found just above the exhaust. Ensure the gindle valves are in the 'closed' position and leave for about 20 minutes.
