I noticed my Transmission Oil Cooler is dripping yesterday. I need to replace it. My question is do I need to upgrade to a better cooler or stay with what I got. It looks like it is the factory setup on the cooler. All I will be pulling with the truck is my 18' Stratos with 150 hp motor. I really don't know what they weight. Also, where would be a good place to look for the part: web?and/orlocal parts store?Any education on this would be helpful.
