Trans Cooler

Ok, so I have some long term thinking questions. I plan on putting a Duramax in place of my 350 when time and money allows. It will have the Allison transmission attached to it; so my question is this: Do you think a separate trans cooler would be better than a radiator integrated one? I notice that there are a few of the newer trucks with separate trans coolers and some with integrated, both run the Allison. I thought it was the a/c condenser at first, but upon closer inspection it was actually the tranny cooler. I don’t know if this is an option or dealer equipment, or maybe just differences in manufacturing. I’m going with a separate stacked intercooler and oil cooler… I think. Any opinions and ideas are welcome as this will be a rather large project that I’m still planning out. Thanks.

I'll take a stab at this. As far as I know,almost all automatics that I am aware of run the fluid through the radiator. If there is a separate cooler,most times it is added on in addition to the radiator integrated cooler. The factory separate coolers seem to be part of upgraded tow packages. So my recommendation would be to run the radiator integrated cooler along with a separate cooler down stream of the radiator.
