External automatic transmission cooler

Got a 2005 MCS with a 6 speed Asian transmission. I just re-built it and now I want to protect it.

Does anyone know if there is a company that makes an external cooler?

I am thinking about building a cooler system by installing an inlet and outlet in the existing transmission pan, in-line pump, cooler and temperature gauge. Any thoughts?

I have done one-off mods like this & found that there are usually flies in the ointment.

You will have to figure out how to support the hoses so the joint thru the pan doesn't fatigue or have some crazy harmonic frequency. Then there is aeration to worry about. 2 things just off the top of my head.

If it was needed to make the tranny live, the OEM would have installed a cooler to protect against warranty failures.

But almost all Asian transmissions die because of the lifetime fill of transmission fluid. This would help
