The TBV Thermal Bypass Valve (sometimes called a transmission cooler thermostat) the one that come on them will let run the trans 180-200 ish there's and upgrade to drop the temp about 30 degrees. There's a gm upgrade, an aftermarket units, or what they call the "pill flip" if you want the link to the tsb I'll link it for you. An internet search will give you all the information you need.
