When I lived I. Southern California with all the stop lights, stop signs, hills, stop and go traffics and of course you know what kind of drivers they home my granny temps would get extremely high, especially towing a 18k lbs toyhauler. After sourcing out the fittings, install and a trip to Yosemite national park my grand temps dropped more than I could have ever expected. Have recommended for others and installed on a friends 3.0 pulling truck. Works great, you won't be disappointed.

this cooler was a great replacement on my A518! the stock dodge cooler was a joke and more than likely the bad name given to the dodge automatics. 100,000 miles later this cooler is money in the bank. I normally pull 15K with my rig and never see temps higher than 210 degrees. dig on the go pedal all you want in the hills and stop and go in the city with that 5th wheel this cooler gets the job done with ease. if you pull heavy with a automatic this cooler is a must! I use it on a 1993 Cummins VE pump with automatic in a 1995 GMC. the transmission would not last before I got the cooler. I killed 2 suncoast transmissions before I tried one of these. no more issues, the fan kicks on with a cheap probe and relay keeping trans cool in traffic and 140 is the norm rolling down the road unloaded. pulling my 53 foot car hauler loaded is 180 and never seen over 210 in the hills. Guys if you have an automatic transmission try this out! heat kills them and this cooler works.
