External Tranny Cooler

[Smithers]

Does anyone out there have any recommendations for external tranny coolers?

We can get the Derale brand external coolers, and I've run them in the past. I've also used the B&M Racing cooler with good success.

Make shure to get a plate and fin or stacked plate type not a serpentine tube cooler (Derale I believe calls them tube and fin). I have personally measured the difference on three of my own rigs and countless customer rigs. plate and fin is at least 20 deg cooler and on my f100 almost 60 deg. also you will want to use the stock cooler and an aux cooler. fluid should go thru the stock cooler then the aux cooler then back to the trans (on 727 trans this is the rear fitting)

Ford diesel HD rig external cooler. If you're into junkyard swaps.
