Holy Carp! The regular block heater takes about 400 W. Your 1,500 W. tank heater is about 4x that amount!
True but you know how massive that tranny is. I figured it was roughly equal to an aluminum block V6 in mass. The 400 watt block heater in my Previa barely warms up the engine afetr a couple hours. having said that 500 to 750W would probably be fine.

Oil dipsticks are only a few watts so they won't fit the bill.
