I have a 1993 Suburban C1500 2WD, 5.7L, 4L60E, 3.73 diff.

I want to add a factory trans cooler (the bigger one from a C3500) as shown in this thread: http://www.dieselplace.com/forum/63...e/154889-over15k-hd-trans-cooler-upgrade.html.

I have obtained the factory (delco) trans line that goes from the external cooler back to the trans. I also obtained a delco line that goes from the upper radiator fitting to the external cooler, but I can't figure out where to route it.

So my question is this: Exactly how is the line from the radiator to the external trans cooler routed in trucks that had the factory auxilliary cooler? If anyone has a truck that has a factory aux cooler and could snap a few pics, I would appreciate it.
