Before we left on another 3 month excursion I put an 8 " electric fan in front of my 68 RFE transmission cooler as they tend to get a little warm in stop and creep when towing about 14,000 behind it. I just put a manual switch in and would flip it on when the transmission hit 200 deg. It worked well it would keep it there or drop it about 4 degrees. i figure it was worth the time and effort to install it. Spare me any any smug AISEN responses . I have 20,000 towing miles over just about every mountain range and desert clime with zero problems with this transmission it works just fine!
