The OE transmission oil cooler is built into the radiator. It's simply a tube in the cold side of the radiator that transfers heat to the engine coolant.
Using an aftermarket cooler is just a matter of mounting the cooler in the airstream somewhere and rerouting the fluid lines to it. I think most applications mount it directly in front of the radiator.
I don't know if anyone here has bothered with doing this.

The factory transmission coolers are a stacked plate style.
Much more thermally efficient than the old "tube" style used many years ago. I don't think GM has used those on anything built in the 10-15 years.
There is an engine oil cooler built into the factory setup.
It's an oil/coolant heat exchanger, built into the oil filter adapter and hiding behind the turbo and catalytic converter.
Really, the best thing to do IMO, is to install an auxiliary cooling fan control switch onto the radiator itself.
This can have a rather big influence on transmission temperatures, and engine oil temps to a much smaller degree
Hers a link to a thread I made a while back on how to install and wire in the add-on fan switch.

I currently have a n auxiliary cooler sitting in the garage for mine. been putting off the installation for a while just because I want to see how bad the fluid gets on a modded sonic after 15k. I'll try and get a write up for this in few weeks. No promises though.
