I would think that a modified dipstick heater would be the way to go for a tranny, aluminum is a great conductor of heat (up there with copper and silver), so you are going to loose some heat heat thru the case, but it seems like you are going to loose less if you are heating the fluid directly, and the fluid is the stuff that is most affected by the cold.
I think that most dipstick heaters are 150 watts if I remember right, so small enough that a Christmas tree light timer should work.
