Hey OC, I was chatting with a guy from Ron Davis Radiator today anc he had a couple of things to note. One was that he said all of the radiators he had with internal tranny cooler failures were with Magnuson SCs on them - specifically this brand SC only. The other thing he said, was that most aftermarket radiator companies still use the internal GM tranny cooler (AC Delco) in their radiators.
I just purchased a custom H2 Ron Davis Radiator and it showed up Friday bent! Then on top of that, they said I had to work it out with UPS as it was shipped perfect and they have pics of it. Worse case, I file claim with my credit card company
