1998 Ford Windstar mileage: 60,000. I will be towing a 2,500 lb. camper on an extended vacation this summer and I want to install a transmission cooler. My Ford service manual says the factory cooler which comes with the towing package (which my vehicle does not have) has a fluid bypass valve that redirects fluid around the external cooler below 32 degrees. Do any aftermarket add on coolers have this valve and is it a good idea for me to pursue buying a cooler of this type?
