Kyle... I don't want to get into conversations how engines work... but...
EVEN THE AUTO HAS A FLYWHEEL
I know you changed yours.. so you know what one looks like..
The inertia in the flywheel is a major part in making any engine smooth running..
and another thing, did you notice that the outer edge is like a gear?? What do you think the starter motor uses to turn over the engine..
The only difference, is a manual flywheel has a smooth ring to take the clutch plate, the auto has some holes that correspond with some pegs on the torque converter.
Nevertheless, it still has one. It is part of the engine, not the transmission..
I can't be arsed putting a picture up. but I am looking at it now, and blow me if the ATX doesn't have a flywheel.. yes it does you know..
