trans coolers
There is a better design, but for a lot more money. Made by Setrab and formerly (& maybe still) by Harrison. It has normal radiator fins between each pair of stacked plates.

BAT-Mocal is one source for them.

FWIW I prefer to put the aux cooler in front of the radiator. The way that I would plumb an aux cooler (& have set-up to do on the FJ-60's engine swap) is before the radiator cooler unless a thermostat is used, then I would put the aux cooler after the radiator. My reasoning is this: The radiator cooler will drive the trans to warm up faster when cold or cold outside so put it last in the system so that it can do that. Let the aux cooler dump as much heat as it can, and then let the radiator cooler moderate the trans temperature.
With a thermostatically controlled aux cooler the radiator can still do the moderation job, and the aux cooler can still do it's job but only when needed - it will be by-passed when not needed. The advantage of such a system is that you won't be working the ATF itself as hard with all of the large changes in temperature. FWIW I see the trans as a fixed thing and the fluid as a consumable.
Want to be very careful with JY sourced coolers. They could have just lost the trans and that resulted in the car being there in the first place. Most that I find I use, after a LOT of flushing/cleaning, as power steering coolers on my off highway vehicles because I view them as being too small to be worth much to the trans. Then again, my now normal aux trans cooler is an 11"X11" stacked plate cooler.
