I've been thinking of hooking up a transmission cooler to my Traverse and I just got off the phone with a manager at one of the local transmission shops and he said that it was my truck and my money and he'll put in whatever I want, but he wanted to steer people away from a transmission cooler for several reasons. First, they tend to leak and if a line blows from the extra pressure created from towing, then you're in a whole new world of hurt on the side of the road. Second, it's a cheap substitute for proper cooling like getting the factory towing package and cooling systems. Third, most of the stuff that is made for these types of transmission coolers are junk and they have cheap aluminum fins that break and/or bend easily. Last, they just don't work all that well. Waste of money compared to the risk of being stranded and/or frying your transmission. Thoughts? Discussion points? Argee or Disagree?
