tranny lines and tranny cooler routing

[saxman]

Ok, I just got the C4 back up after a fresh rebuild. I am plugging in an external tranny cooler made by B&M after running the AT fluid through the main radiator. When taking things apart, I noticed that the pressure port from the tranny(the front port closest to the engine) had been routed to the upper radiator port. Tranny fluid would then run down with gravity and then out the bottom and back to the tranny. I thought that it is best for all pressure to enter the bottom port so it could push air up and out the top port if need be?

So, is it best to route my lines like this?

1. tranny pressure out to the bottom of main radiator
2. top radiator out to bottom port of external cooler
3. top external cooler out and back to tranny

Hope this makes a mess of sense.

Thanks!

Makes no diff, it's pushing any air out within seconds after start either way it goes.
