Transmission cooler line connections from transmission to radiator

3rd times a charm I hope!

When it comes to the radiator lines, in and out of the cooler. This applies to the factory cooler at the bottom of the radiator OR an external unit.

If you run an external/remote/additional after market cooler, the lines should go through the factory section first, aftermarket unit second, which should be mounted in front of the radiator directly in the wind. A straight line of sight for the air to pass through it.
