Review on 🚗 Enhance Your Transmission Performance with Derale 13504 Series 8000 Plate and Fin Transmission Oil Cooler in Sleek Black by Reggie Kern

Got this for my 2015 Toyota Tundra 4.6 liter engine. It is also necessary to buy a Toyota thermostat for 4.6 (the part is specified for a 2014 truck). That kept my gear temp down 20 degrees the whole time. Before installing this cooler, my transmission would hover between 200-220 on normal driving, peaking at 230 when towing a 5,000lb trailer (not sure which would be higher as I stopped at that point to let it cool down) . After setting normal driving floats between 180 and 200. Usually around 200 when towed. The max temp I've seen is 213 after installing this cooler (third gear 55 mph uphill towing).
