Rob,
I have one of the Aluminum GMC radiators that had the necks modified-different sizes and locations. I think the lower hose location may have moved it into a more restrictive (water flow) situation as the oil cooler ended up right at the neck opening. At the time there was also a concern with the internal heat exchanger-in my case the lower cooler in the tank, fittings leaking as they were not welded like the upper heat exchanger is. I chose to simply install plugs in the lower cooler and crush it to get more water flow through the lower neck.
I mounted an air to fluid cooler for the trans and also used the in radiator heat exchanger. Trans temps seldom exceed 140F.
Carey, I'll try to get some pictures but it may be a while. I'll have to remove the inner wheel well to document the install.
Hal
