ATF automatic transmission fluid has fairly good thermal conductivity (for petroleum products) and lubricating quality. It is also a non electrical conductor. It may even be cheaper than mineral oil. Ford AODE and GM 700R have the controller chips immersed in it. Dexron III and type F (10w) has a lower viscosity than Dexron IV (30W ). If you are handy with a lathe and mill... rigging a Small block chevy oil pump to move the fluid through a automatic transmission cooler would not be that challenging. The question is would it eat the mobo and any other plastic parts? If you like the color red It would be great.
