Is 5th Gear Still OD in Gen 3

Following your prompt and Skidog’s suggestion, I looked my VIN up and saw that I have a tow package, that includes oil and tranny cooler. I guess my confusion originated when I cross-referenced my door data plate with the manual. That rubric indicated that I didn’t have a tow package. In any case, when I lifted the hood this evening, I saw two coolers. One on the top right front of the radiator- a box shaped one about 5x8 inches. Possibly a second cooler at the bottom of the radiator that are two finned tubes about 10” long.

Do you know which is which?

 

I don't know what that circular thing is. The second picture is the tranny cooler.

 

Thanks!

Maybe that’s the power steering fluid cooler?

 

Yeah, have no idea. Don't recall seeing it on my 2015. Doesn't mean it isn't there though...lol

 

The manual on my 17 says S5 and ETC. Truck won't spend much time in 5th towing anyways.

 

Round tube w/ round fins is a "finned heat exchanger". Could easily be for engine oil.
