I see a lot of recomendations for Plate style coolers over fin coolers but why? What is the difference and hows it effect its performance?
 
The stacked plate style, the fluid is pushed out into countless little passages, so it has more contact w/ air. With a tube & fin style, the fluid in the center of the tubes stays hot & only the fluid against the outside of the tubes is getting contact.
 
In addition, most quality stacked plate coolers have bypasses built into them that allow oil or ATF to avoid being cooled until it's necessary.
 
stacked plate is a minny version of the radiator in your rig. thay have run this style for years cause it works better.
 
Not to mention that most plate coolers can take a serious hit from debris or tree limbs without damage and a tube cooler will split and spew fluid.
 
The best are the stacked plate with fins btwn each stacked pair of plates. Setrab makes them. Bring your wallet.

Tube & Fin type coolers have lots of fin surface area, but not a lot of tube to fin contact area. There are some really well built versions of this type that seem to do a good job, but most of them you'll see are cheap and of poor quality.
Fluidyne makes both types. If you are determined to use a tube & fin type, they are the only only one to use.
 
I ran the standard tube & fin cooler for my tranny. I switched to a stacked plate cooler and it works much better.
 
Thanks guys. THe first two posts explained it well. I never planned on getting the tube and fin style just wanted to know why the plate was better thats all.
