Johnny, I used the upper for the trans as the plumbing worked better on my application. The 4L80E trans has the lines on the right and the 6.5 has the engine oil cooler lines on the left. The in tank coolers are on the right hence the routing. The 6.5 uses -10 lines where the oil cooler lines for the GMC were -8 and I didn't want a potential restriction. I used a B&M 29,200 BTU cooler for both transmission and engine oil as well as the 'new' additional engine oil cooler.
I moved the 12 volt fan from in front of the radiator cooler to the new oil cooler in the wheel well. It's controlled by a thermostatic switch located at the forward cooler with a manual override. It hasn't run yet but I'll wait until next summer to know for sure if it's needed.
Fun stuff isn't it?
Hal
