Simple Green is the answer for everything.
Spray it on full strength, let sit 10,15,20 or so minutes and hose off.
Even better, agitate with a brush before rinsing.

I seek list wisdom on cleaning the oily residue off of the items that
have been sprayed  with hot ATF.  I especially would like to prevent
damage to the hoses, thermostat housing, wiring harnesses in that
area.  Should I even clean it?  If so with what?  I was thinking
maybe some purple degreaser cleaner in some dilution, mop it around
with a brush and rinse with hot water?
