Ok so tranny fluid must go in to Radiator then to external cooler in front center . But I must not have the engine oil cooler . There's no fittings on driver side Radiator. But it does have the 2 big electric 2 speed fans and no fan on motor.

Correct. 05 was the first year of electric fans. Your oil cooler lines are capped off with the block off plate if you don't see the lines coming into the radiator on the drivers side.

I bet they figured with that much fan the engine oil cooler wasn't needed . I could always add external one I guess then . [emoji106][emoji16]
