the light duty cooler will be more than adequate. the radiator side tank is a terrible excuse for ATF cooling so don't let the label "light duty" fool you into thinking it doesn't do much. if you are racing or towing and subjecting the motor to abnormal useage *maybe* a larger one would be in order, but even in that case a light duty would be fine.

 

oil coolers are a good option for turbo vehicles, but i'm not very experienced with those. use the recommended standard ATF unless you're having some transmission issues you're concerned about. Redline is a popular aftermarket ATF option. i know some people on here running it.

Does your new radiator have the piping for the AT fluid? You could just cool it through there. My 3.5L Mopar runs the ATF thru the radiator and another cooler.

 

Standard ATF is fine (whatever is recommended), but AMSOIL makes ATF as well.

Sure, your mopar works fine with your mopar's radiator ATF cooler...

 

The coolers on the subaru radiators for the AT fluid is really crappy. Its okay, but if you do any driving in mountains, driving fast, towing, etc, it quickly gets overwhelmed.

 

A light duty cooler will be so much better. You'd be fine with the light duty cooler, and just completely bypass the radiator cooler.

Good to know. My '90 A/T turbo didn't die until it started getting HOT here in Florida; I've been looking at those cooler kits in Advance stores for a while now, thinking that "it can't hurt; and it might help...."
