Which hose on the 700r4 is the output and which is the input? Also on the radiator which tranny hole is for the input vs output?

I'm planning on also having an external cooler, so how should I run the lines?

Thanks

This is the response I got when I posted this same question:

With regard to the T-700, the upper line is the return and the lower is the output. I recommend installing the temp probe in the lower (hot) line. It more accuratly reflects the operating temperatures inside the transmission.

Hope this helps :)
