here is what they say on their site.
"If you are in the Northern part of the country where you have extended periods of freezing cold weather, and you are installing a large cooler, we suggest the "Tru-Cool" self-regulating coolers. This will help warm your transmission up to operating temp. faster in the cold winter months.
If you are in the South there is not as much need for this feature with warmer winters, unless you are adding a very large cooler or bypassing the transmission cooler in the radiator."
This where I bought mine. Tru-Cool Heavy Duty transmission cooler: Bulkpart transmission parts #4739
One thing I learned when I installed mine, do not use the worm clamps they send in the kit. I had one fail on me and wiped out my trans.
Go to your auto parts store and get some fuel injection clamps.

I live in Eastern Idaho an work in the public schools. I was out all last week due to snow and wind making the county roads unsafe for the school buses. If it's not too spendy the Tru-Cool may not be a bad idea although I've never had a vehicle with one yet so I guess I should save the coin
