Only if you're planning to pull a trailer through the mountains. Otherwise, we recommend against it on vehicles with the 3800 FWD/4T65E drivetrain.
We have dissected more of these trannies than anyone else in the performance aftermarket, and we have yet to see a single heat-related failure. Hard parts break in these trannies, and these failures will not be prevented by a tranny cooler.
Tranny coolers add unnecessary weight and opportunities for fittings to leak. A leaking fitting can let your tranny run dry in minutes and ruin it far faster than a little heat ever could.
Our trannies are cooled by the same radiator used to cool the engine. So running a colder engine thermostat will make both your engine and your tranny run cooler.
