Auto Tranny Cooler?

[Turbolader]

I've done a few searches, and haven't found anything, but given that Auto Tranny life is substantially affected by the temperature of the tranny fluid, I'm wondering if anybody has installed an additional tranny cooler?

Searches didn't bring up anything conclusive.

I've run tranny coolers on many of my past-AT vehicles and never had a tranny failure (Granted, I never keep them long enough to find out...)
