Dodge Cummins Transmission Coolers, Lines and Accessories

Diesel transmission coolers are important components for the safe operation of your pickup. For your Dodge Cummins automatic transmission coolers, you need reliability and durability to keep your components within their appropriate operating temperature window. Pure Diesel Power offers Dodge Cummins transmission cooler lines, thermal bypasses, oil coolers and heat exchangers so you can optimize the performance of your transmission. Choose just the parts you require or purchase a diesel transmission cooler kit that comes complete with everything you need.

Why Automatic Transmission Coolers Are Important

Your Cummins transmission cooler is responsible for balancing the temperature of the transmission fluid inside your closed system. Dodge Cummins transmission cooler lines transport fluid between the transmission and the cooler, typically passing through the thermal bypass along the way. Without your automatic transmission cooler, the fluid would become too hot and potentially burn, resulting in irreparable damage to your transmission components. With a proper diesel transmission cooler and thermal bypass, your fluid viscosity stays at its proper working temperature, reducing wear and maximizing efficiency.

Buy a Cummins Transmission Cooler From Pure Diesel Power

Replace your Dodge Cummins transmission cooler, lines and thermal bypass with a full installation kit from Pure Diesel Power. Our inventory covers all aspects of your automatic transmission cooler for most model years and generations from 1994 to the present day. Can't find exactly what you are looking for? Contact our customer service team and we may be able to source your parts without the hassle of splitting your order or calling dozens of manufacturers. Find your diesel transmission coolers online today at Pure Diesel Power.
