How To Remove Trans Oil Pan?

[Gregski]

"Do you even know how to drive an automatic?" the famous Hangover quote comes to mind

So I am not a complete idiot but whilst lying under said ride a gorgeous 1969/71 350/350 true short box GMC 2WD I realized one may need to move the transmission crossmember out of the way to get to the rear 2 bolts on the transmission oil pan in order to drop said pan.

Man, I thought... them TV car drama shows never show that, they just go bzzz bzz , ha ha and the next thing you know their trans pan is in their hands.

So my question is, is that how it be on these trucks or do I have a non OEM cross membrane on mine?

I will upload a pic after I have some scrambled eggs here this mornin'.
