Also, what's up with my truck; oil cooler but no tranny cooler. I see the A/C on driver's side and the PS cooler and oil cooler in front of the radiator. Am I missing it? If I don't have one, I guess I'll install one later this summer.

 

Nevermind, I was actually back up under the truck and saw the return lines to the tranny. From the top it looks like the lines run right into the engine where the oil filter is. Kinda hard to see. Aren't i the dumb **** today. Ha ha. Regardless what is the difference in heavy duty engine cooling and regular duty engine cooling. Where did the extra $$ go.
