c6 cooler flow direction

[mrollings53]

Which port is which for the transmission cooler lines on a C6. I want to make sure I have the auxiliary cooler setup so that the fluid flows through it last before returning to the transmission.

The front port is the output to the radiator/cooler. The rear port is the return. Output would be the one closest to the engine in other words.

Thanks for the help.
