high temp enamel paint on aluminum?

Does enamel paint (on the outside of course) raise the internal temp of a transmission?

Or are there any other reasons that his would be bad?

yes, painting the bare aluminum case will hold the heat in.

it would be bad because tranny fluid eats paint.

have a nice day!

You will see no difference on temps with a light coat of paint on the transmission.

I think I will leave the paint. A large trans cooler and some synthetic fluid should negate any increased temps caused by the paint.

Thanks for the input.

It won't matter. This isn't the technical explanation but you'll get the idea.

A specified material will only move heat through and away or into something else at a certain rate. Some grade of steel will allow heat to travel through it at a different rate then say, aluminum. You can get the technical explanation on heat transfer and coefficients from a physics forum.

Bottom line-A light coat of engine style paint won't slow it down.

Notice that I answered without using the terms conduct, radiate...
