It's a pretty simple deal. I went to a Napa Auto Parts store and bought some Marine grade 1/2" hose and hose clamps. I went to Home Depot and bought the barbed fittings to step down from 1/2" to 3/8" lines.
I removed the 'cooler' cover between the radiator wall and the grill. I took the hood latch outta the way. IIRC, there are some brackets at each end that hold the AC condenser in place. The trans cooler sits down low between the AC Condenser and the Intercooler. Disconnect the rubber tubes from the old one and unbolt it. The 6.0L cooler (31-row) bolts right in place of the stock (9-row) cooler with its tube ends facing down. I made all my connections below the cooler in the cross truck pan thingy below the radiator. It isn't a hard job, just takes some time. Don't get into a rush. Unfortunately, I didn't take any pics. This might provide you the opportunity to do the write up with pics. You'll be famous!!!
Once you get it all installed, check your fluid level. I think I had to add a quart. Your tranny will thank you - Mine runs much cooler now.
