09 4720 cab has a coolant line hooked to the hydro filter?

Anyone else see anything similar? If you stand on the passenger side of the tractor, look low, right to the right of the big hydro fluid filter thats near your back wheel, there is a black 1.5"-2" hard metal black tube/line that runs into the trans side of the filter area. This line runs all the way from the front right side of the engine block, and has a "flexible" 3" long hose that connects it to the engine, assuming its not exhaust circulation because of the rubber coupler, it could only be engine coolant? The line gets warm warm when the tractor is running.

Ill get a picture but everythings shiny black so it wouldnt be easy to see online anyway.

My dealer told me there IS such thing as a trans fluid warmer, for extreme cold climates like alaska/michigan/maine etc... but as far as i understood it was exhaust that circulates from the muffler? Am i going nuts or what is this 4' long tube from engine to trans hydro filter area?

It's the hydraulic suction line.
