Ram Cummins Mishimoto Transmission Coolers Breakdown!

Ram Cummins Mishimoto Transmission Coolers Breakdown!

Both the 5.9L Cummins and 6.7L Cummins Ram 2500 and 3500 trucks are able to tow heavy right out off the showroom floor and make a whole bunch of power and torque with relatively few modifications, but doing either (or even both) generates a lot of heat. That heat can lead you at best waiting on the side of the road waiting for your Ram's transmission to cool down and at worst can hurt your transmission to the point where you'll need to get it replaced. That's why our good friends over at Mishimoto have put together a full lineup of drop-in transmission coolers that can help your Ram's transmission stay in a safe temperature range, even if you're towing extremely heavy uphill or if your truck is throwing down a bunch of extra power that's causing high operating temperatures.

Top Transmission Cooling Upgrades for 2019-2024 Ram 2500 & 3500s!

Top Transmission Cooling Upgrades for 2019-2024 Ram 2500 & 3500s!

The 2019-2024 Ram 2500 & 3500s with 6.7L Cummins diesels are some of the mightiest trucks on the road, but they certainly generate a ton of heat, especially if you turn up their power, tow extremely heavy, throw down at the track, or rip around off-road. Heat's not great for basically any mechanical component, but it can be real killer for your truck's transmission, especially for the particularly finicky 68RFEs in the Ram 2500 and some Ram 3500s. The good news is that we here at Tier One offer more than a few transmission cooling upgrades that will keep your Ram's transmission temperatures under control, even if you are stacking on the power or using your Ram how it's meant to be used on the road, at the track, or out in the dirt.
