transmission cooler lines, rubber or metal?
The OE lines that come out of the tranny to the radiator and back are metal. It seems to me that if at the pressures and temperatures involved that if the manufacturer could have gotten away with rub...

Soft lines can be built to be just as strong as hard lines.
OEMs use hard lines because they can be installed as an assembly and don't require additional steps to secure the lines to keep them in place. Some OEM systems use soft lines as well, especially where vibration needs to be isolated. Even in assemblies with hard lines, there is usually a segment of soft lines because the powertrain moves on the motor mounts, but the radiator and cooler are fixed to the body.
As mentioned, just be sure to select the correct soft line for a hot-oil application. Be careful to maintain minimum radii so the hose doesn't kink and restrict flow.
If you are really concerned, upgrade so silicone line. They age better and are more tolerant to extreme heat if you are running the lines near exhaust components.
