Hey all, been awhile since posting, the 3.7 KJ is doing well. My wife and I are purchasing a small 2900’- 19’ long (Cherokee Wolf Pup 14cc) trailer and I’m trying to figure out if i have the “aux” trans oil cooler. My trans only has about 20k on it as it was a new install a couple of years ago. I don’t have the official tow package, but I am adding the HD fan setup with the mopar parts. He Jeep already has OME shocks and springs as recommended by Tom, and running 275/45 16 tires. Its seems I’ll be good to go overall, but with Colorado mountains and what not, I want to be sure I don’t cook my trans. I’ve got the small narrow cooler that sits in front of the radiator and the AC, so it basically looks like I have 3 radiators. Is this small, forward cooler the aux cooler, or is there something I’m missing? I searched and didn‘t find anything definitive? Any tips/tricks would be appreciated!
