N55 335xi automatic performance radiator.

Does anyone know if there are any options for an automatic 335xi n55 performance radiator?



The only option I seem to find is to buy an aux transmission cooler and upgrade the radiator to a performance one that states "Manual only".



I was looking to see what is different about the radiators on the manual and automatic but I was unable to find a decent drawing or picture. Does anyone have details on that?



Thanks,
