So, about to do a radiator flush and replace all my hoses but I'm a bit puzzled about the aux trans cooler. Truck has the factory HD trailering package w/FF rear axle and 13" JB7 brakes (3/4, 454). Also has the factory engine oil cooler. Truck is very original overall with only 2 previous owners I believe, and the one before me was a buddy that had it for 10 years so I know what maintenance he did.
The hard line from trans on upper part of radiator has a fitting, but the rubber hose to cooler is on there with a worm hose clamp. I've attached photos. The cooler itself looks a little rough and discolored - is that normal? Is there a way to test it? Is this the OEM cooler, or a replacement? Anyone got pics of their factory cooler? I know there could also be dealer installed aux coolers, but since it should all be there coming from factory I just don't understand the way the rubber hose is connected - is there a fitting adapter that is missing? Maybe someone replaced cooler at some point with aftermarket?
