I was wondeiring if anybody has done this? Is it recomended? Im contemplating the idea of putting one on my 89 when its back on the road. I already bought a 24k gvw B&M cooler and a fan sounds logical, but i've read that if you keep your trans fluid too cold, it could end up being detrimental to the transmission. A good way around it, and what i plan to do if I get the OK on the fan, is just wiring the fan to a switch and letting the tranny warm up, then fliping on the fan when necessary instead of having it wired to come on with ignition (like the IC fans). Your suggestions are much appreciated.
