727 fluid capacity/cooler preference

Adding a trans cooler to the car....
When doing so does the extra fluid cause an overfill situation causing it to leak out the vent in the front pump /drain back??

Read alot about the difference between the stacked plate / tube fin designs...

Alot are saying (Deisel/truck guys) that the stacked plate design can clog and they prefer the tube design because it allows debris to get to the pan...

any experience out there??
