heat sink transmission oil cooler

If they all require airflow then how is a stacked plate cooler any different if the car is not moving?

Maybe I need to call some trans builders and see what they say. It's hard to find definitive info on these things.

A lot of people put them in the path of the fan or even have an extra fan for the cooler.
I'm not saying anything bad will happen, or that you can't/shouldn't use it.
It would probably be fine though the trans will run cooler overall with the older style.

Top 5% in the state at the time actually, but more opinions can't hurt, right?
