Band adjustment

I drilled a 1/8 hole in the right front corner (under the filler tube) to drain it.
Then a sheet metal screw with a dab of silicone on the inside when the pan goes back on.
Not too good if you plan on bottoming your pan on something while driving , but works great otherwise. (Never been an issue)
I wouldn't do it on a 4x4 though.

Some trans shops do the same thing and put a pop rivit in it when they put the pan back on.
