Agreed, heat is by far the #1 killer of autos, even in a stock application you wil pick up much needed longevity with one. Just ask the 4R100 in my Stroker
I have a 19,000 GVW B&M cooler on my bone stock AOD. Worth every penny. I would get the 24,000 GVW if I had it to do over. The bigger the cooler the better.
