Is this tranny cooler better than the 40,000GVW that tru-cool sells?

eBay Motors: Perma-Cool 12311 Oil Cooler, 10 1/2"x14"x3 3/4", 10"Fan (item 220367009657 end time Mar-24-09 23:35:57 PDT)

Wondering because the guy installing my cam and stall has one, but it doesnt say how much GVW or anything..
Thanks
