How will a hayden 1401 tran cooler work its for gvw up to 12,000. I think it should cool better than the stock trans cooler right ?

In conjuction with the stock in-tank tranny cooler, it will be an improvement. Don't run it by itself though. From what I know, the 700R4 wouldn't mind having a much larger cooler than 12K GVW. I've got a 26K GVW cooler and the in-tank cooler for my 700R4.
