... they would not have used a standard hex head bolt for this function, but instead perhaps some sort of a fancy tamper-proof bolt so to discourage the casually curious folks like myself.
The Drain plug is on the bottom of the differential.
The Fill plug is on the side of the differential

Fill Plug(Make sure that you can loosen it before you drain the old oil):


Drain Plug:


Those bolts on the side of the transmission that Dave80GTSi is playing with are obviously just shills to discourage people who don't read directions from tampering with the important stuff.

I think that the intent of this thread was to point out that drilling a hole in the pan beneath the drain plug makes servicing the transmission a lot easier. (Thanks Monty)
