I like your idea of transmission lines.

If they vibrated, the shaking could very well transmit into the radiators cooling coil for the transmission. Does one side of the radiator hum more than the other?

You might want to look and see if you can tie the two lines to each other to help stabilize the lengths in the middle. You don't want to have them rub anywhere on a casing or within a mounting bracket as that is how leaks happen!

Peek out the supports, thump and shake them about for good measure!
