Up grade transmission cooler?

[basilry]

My transmission cooler just started leaking and from what I can see its leaking from the fins. I dont know how or where it is exactly but it seems to be leaking from the upper left hand corner. So I called the dealer and they are of course out of stock and on back order and they have been for a while from what they told me. I was wondering if there are any good upgrades to install instead of putting in another stocker. I was going to pull it this weekend and take it to a radiator shop and see what they can do for me. Any suggestions would be appreciated. Thanks

The factory cooler is thermostatically controlled, So the aftermarket would need to be also. The Factory unit is well designed and works well even with complete build transmission.
