I just got an 87 XJ with a 4.0, AW4, and the factory tow package. This is my first automatic ever so I'm very new to them. I was just wondering if there is any need to upgrade the factory trans cooler. I know there is an aux cooler in adition to the radiator one. I don't plan on doing any heavy towing, but a lot of wheeling in excessive heat (read: Moab). Is the factory cooler up to the job or should I look into upgrading? Disclaimer: I tried searching, but couldn't find what I was looking for.
