Ford Freestar transmission cooler
I have a 2004 Freestar with the 3.9 engine. I pull a small enclosed trailer with it, and occasionally pull a 10' popup camper. The van has 125k miles on it. We just lost the torque convertor last month (thankfully there was a recall on it). So, I have a new torque convertor and fresh tranny fluid.
This summer I'm taking a longer trip with the camper (300 miles each way), and want to add a transmission cooler. I'm wondering how hard of a job this is as a DIY project? Looking at pictures, it looks like you just bypass the lines where they run into the radiator? Anyone have perspective on how difficult it is to add one to a Freestar?
Also, being I have brand new tranny fluid in it, I really don't want to have to replace it. If I do a tranny cooler, do I have to drain the tranny?
