The absolute best is the largest stacked plate style with it's own fan and built-in t'stat. It can be mounted near the transmission and not plumbed into the rad.
Next would be the largest stacked plate style with built-in t'stat and mounted in the main airflow ahead of the A/C unit and plumbed after the rad.
There is no such thing as too big when it comes to trans coolers if a t'stat is in the flow.
You DO have a trans temp gauge right?
Get a ScanGgauge.
Easy to use and economical.
Have a safe Summer.
All items are on the Internet and/or locally available.
