    I am using the Derale electric fan powered trans cooler. It cycles on and off as needed. Rock crawling doesn't seem to heat up the trans that much. Pulling a trailer or steep hill gets them hot.

    I would definitely look into adding a tranny cooler to your rig and it's certainly worth it. I installed one on mine shortly after purchase after hearing about the hot oil issues that they are known to have. Mine is an 08 also. I went with the B&M super cooler, part #70268. Good luck and if you have any other questions, feel free to ask.

    I have B&M Transmission Coolers. For the price it gets the job done.

    I'm also interested in hearing what everyone uses.

    Additionally, If you have one, how was the install?

    Anyone notice a drop in temps after install?

    Any justification for the pricing differences?

    I'm running 4.88's with 37's and intend to pull a small popup come February.

    The install was super easy. I was a bit skeptical at first but went for it and it turned out to be way easier than I thought it would be. I'd say the hardest part was getting it mounted and figuring out how to use the brackets to get it straight while keeping a bit of space between the cooler, the bolts and the radiator.

    The difference in temperature was almost instantaneous. Before the install, I started up the Jeep for only a few seconds while I went underneath to find the transmission lines. One should be a bit cooler to the touch. Well, both of them were almost so hot I couldn't touch them at all. After the install however, I drove from Tempe to West Phoenix, parked and went underneath to check for leaks or anything out of the ordinary. I touched the lines to see if there was a temp difference and I could actually hold onto both lines without burning my hands or it getting too hot I had to pull away! I couldn't believe it and I still can't lol. This was also done in January and I wouldn't touch anything underneath there at this time of year. Shit, you can't even touch the steering wheel lol. At the time of install I was running stock gears with 35's. The cooler was totally worth it!

    The 3.8 auto trans practically requires an auxiliary cooler. The B&M model mentioned is very popular and easy to install. You can find good installation write ups easily. Just be sure to plumb the lines trans > stock cooler > aux cooler > trans.

    Mopar sells a really nice fitted kit, too, but it's a couple hundred bucks more than the universal ones.

    The B&M 70268 does a great job. I've run one for 5 yrs now on my 08. I was horrified that I was seeing temps well over 200 in traffic and on mountain roads. I haven't seen 180 with the cooler.

    If you run a 3.8 without a cooler, check your ATF for darkening (should be bright red) or any hint of burnt smell. ATF+4 are all the same and can be found for ~$5 per quart.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
