Allison cooler?

[loco4fishn]

I was wondering if anybody has put a secondary tranny cooler on an allison, and where they purchased it. I was running down PINS and am having my trans temps in the 200-250 range. This has happened to me twice while running down the beach. Is this normal? Any info is appreciated. Thanks.

Could be leaking fluid, filter could be clogged, fluid needs to be changed, the list goes on and on.
