What size transmission cooler fittings on radiator?

[Cannoball888]

I got a new aluminum radiator that has a tranny cooler. I have a manual so I just want to plug the ports in the radiator to keep dirt out. I tried a brass 1/4" plug but it was too big.

Sooooooo, what do you want us to do ?

What size should it be? I thought 1/4 was the smallest fitting size.

There's also 1/8" pipe too.

Yeah. The guy who answered the phone at Griffin radiators was clueless about the size. I just found that out from my own searches on the web that 1/8" is common.
