Paint the transmission?

[Calabrio]

My new transmission just arrived this morning. Before it gets installed, would I do any harm by painting it with a coat of POR or something like that?

I know it's not necessary, but it might be a nice cosmetic touch and it can only be done while it's out.. Is there a downside to doing it?

If you think I should- what color/brand.

What transmission did you get and where?

A friend of mine with a few Kennedy Transmissions up in Minnesota built it for me. It's a rebuilt 4R70W with a shift kit and some valve body work. I've known him for a while and I've heard nothing but praise for his work. So when the time came to address mine, I contacted him.

But now I'm just wondering if I should paint it black... I don't think POR comes in any other color.

Can't hurt anything at all. My transmission case is powdercoated and I have never suffered any problems. It is a standard option from most transmission builders. Cost me $150 extra.

I think 94m5 will probably have better recommendations than I on the how/what to use for painting, but no, it will not hurt the transmission in anyway.

BTW, I had mine done in black to match my scattershield.

I didn't think of powder coating the transmission until the other day, and then it was too late.

I was thinking I could just get a pint of black POR-15 Rust Preventive Paint and apply that, carefully. I think that limits my choices to black or black though.

The surface isn't clean enough to use the Engine Enamel paint.

POR comes in silver too!

POR comes in silver too!

Yeah, I see that now.
Black, Grey, Semi-gloss Black, Silver, and Clear.

Any down side to doing this? Any chance it'll make it more difficult to cool?
Any benefit?

Actually- there's no rust, so I could just use a high temp engine paint....

POR comes in all sorts of colors. They had the correct Mopar colors for my engine, which I did. High temp engine paint should work too.
