Use 15w40 in the engine if you want or stick with 30 either is fine in the engine. Use cat spec tdto 50 in the finals and a TO2 at leat approved 30 weight in the powershift or better use the newest spec 30 that meets the newer cat oil. I use cenex power transmission fluid in the powershift and cenex 50 tdto in the finals
