i just realized you have an automatic. the safe way is to block the flywheel from spinning through the little access panel. but....you probably don't have a tool for that. which makes it a little difficult. if it was me and i was going to do it by turning the engine over, I'd pull the spark plug wires. the car can't start so no real danger.

i didn't read through the whole thread, so i don't know if that was covered.
