Transmission drain plug

[ecoboostsho]

Stupid question of the day.  There are two plugs that look the same on my transmission...was going to drain out 5 quarts and put 5 back in.  Which plug do I remove?  I assume it is the one that is "lowest" on the bottom (i.e. closest to the ground) but wanted to make sure...

Thanks...
