The supplier made good on refunding my money and shipping. The radiator order was confirmed with my vin and this is the original radiator and transmission lines. These cars are worth the extra expense, trouble and headaches but it can be frustrating. Scott

You say the fittings bottom out and don't allow fluid through the radiator properly, was it obvious this would be a problem when you installed the radiator?

The reason I'm asking is that I had an unusual problem that my transmission started overheating after I had new genuine radiator fitted. I'd never had problems with my transmission before, but after the new radiator was fitted the transmission oil would increase until the transmission overheated (refusing to kick up into higher gear). I put sensors on the in and return lines and discovered the temperature drop was only about 1*C. I'm just wondering if what you're describing was the issues - but my mechanic never picked up on it.

I eventually resolved the problem by fitting an external transmission oil cooler.

Note: The engine coolant temperature was always within the expected range.
