From everything i have read on transmission coolers, the stock ones are usually too small. My E450 has a factory transmission cooler separate from the one in the radiator. I am assuming they are plumbed in series. ( i havent checked). BUT if you want to go with a aftermarket cooler, the consensus is that the "stacked" coolers are better than the "tube and fin" coolers. And get one size bigger than is recommended by the manuafcturer, as long a it will fit where you need to put it. I guess the old saying is true. " bigger is better"
