WARNING: This page is about a different car, the 2015 RAM 3500 HD and 2015 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
All diesel models equipped with an automatic transmission are equipped with transmission oil coolers. The automatic transmission coolers are supplied as standard equipment on diesel engine powered models when equipped with an automatic transmission.
There is an end tank transmission fluid cooler located in the right side tank of the primary radiator, as well as an externally mounted air-to-oil externally mounted transmission oil cooler located in front of the primary radiator.
The end tank transmission cooler is not accessible for service and is serviced by replacing the radiator. The external cooler and jumper lines are available for service separately.
