What is the best trans cooler? Plate style or tube and fin? I am going to be putting one(or more) on my tow rig. 1992 dodge D350 dually Cummins turbo diesel. I plan on using a fan cooled one and mounting it under the bed. If I have to spend $300.00, I will. That is alot cheaper than rebuilding the trans.

I have looked at Summit and a couple of other places and I would like some real world input before I make my purchase.
I will also be addind a Mag-Hytec double deep pan(extra 4 quarts). My ultimate goal is lifespan of the transmission.

I will be plumbing in the remote cooler with mostly metal line, so that the line itself will help with cooling.

So whatcha got?

I believe the consensus is the stacked plate style. I've always put B&M kits on my trucks, getting the biggest I can fit. If it gets COLD where you are (Dallas? I doubt it) some folks will tell you that you could have too cold fluid ... unless you're in Alaska or Nebraska, I doubt it. I believe that there is no such thing as too cool tranny fluid ;)

If you're buying from Summit, look at the "racing" models that don't come with all the plumbing stuff, as you're gonna be piping it anyway -- cheaper that way.

The fan-under-the-bed thing ... sounds overly complicated. Why don'tcha want to put it up front by the radiator like everybody else?

Oh, and a temperature gauge will give you great piece of mind.

Definately a stacked plate cooler. Having a fan on the cooler really doesn't help much except at idle when there is no air flow across the cooler. Even with the cooler mounted under the bed there is plenty of air flow there while driving so i wouldn't waste money on buying a cooler with a fan attached or buying a fan separately to mount to the cooler.

By the way, trans fluid can be too cold and ruin a tranny. The fluid needs to reach a certain temp (usually around 160*) to burn off any moisture in the fluid. A temp guage would be ideal as well and try to keep the temps between 160-180* higher when climbing hills is expected.
 
I use these..

I use a B & M stacked plate. To keep tranny fluid at the correct temp when it's cool out, I have a thermal bypass valve installed as well. No fan.

I'm with the Valley girl, but with a fan!:D












:p:

OK, I'll try that one. I am putting two trans temp sensors on my truck, along with a Mag-Hytec double deep pan. My trans has a non lock up converter, and when pulling my trailer with Blazer at the non overdrive speed of 65, I'm thinking I need all the cooling I can get. I can always add a fan later and If I get the 160* thermostat for it, it should be right where it needs to be. Thanks guys.

stacked plate has more cooling surface area- plus flows a little better- Some of them have designs that go automatically into bypass mode if it isnt past a certain temp. Trans temp gauge is definately worth it, you can get the permacool remote filter + gauge pack.
Uses fl1a filters, takes the pain out of changing filters.

Got a link for a thermal bypass valve? It gets damn cold here in febuary in Iowa
