Which Behr Radiator was OEM?

So I've been searching for hours everyday, and I can't figure this out.

I have a 2003 E55 (65k miles) that I just purchased. I'm very worried that coolant maybe leaking into my transmission, as it has hesitation shifting into drive or reverse, from park or neutral.

Autopartswarehouse.com has 2 Behr Radiators listed that are supposed to fit my W211 E55. I can't figure out which one is the correct radiator to purchase. The part numbers are different. I've googled the part numbers, and tried cross referencing with different websites, and called a few vendors with no luck. Any help is greatly appreciated.

Radiator 1:
Behr; part no: 376718011

Radiator 2:
Behr; part no: 376718021 http://www.autopartswarehouse.com/sk...376718021.html

Not sure about the part #'s but there is a glycol test that can be done for you to know for sure if there is coolant in the tranny fluid. I believe member Shardul posted before that he can get one of the test kits, PM him about it, hope that helps.

Thanks! - I'm definitely going to do a glycol test, just to see if any damage has been done. I also think that I am going to preemptively replace the radiator, as I can't afford a new transmission. Just having a hard time figuring out what radiator to purchase.

Have you tried contacting BEHR directly? I'd imagine they have some sort of customer service that could help you with this. Please let us know what you find as info on 03 E55 radiators is scarce other then the fact that one version leaks internally sometimes.
