School me! C4's and AOD's?

here's the easiest way - look at the trans pan

 

An aod will have wires coming off of it, but they are for the backup lite and the ign lock out.
I used to have a pictures showing the difference in the oil pans for the different transmissions, but can't find it right now.
Do a search on here and/or google for aod and you will find a wealth of info.

Boy am I a slow typer. hotroddon got up a picture similar to the one I was looking for.
