The liquid to liquid transmission oil cooler in your 5.9L Cummins utilizes the trucks coolant system to cool the transmission fluid during hot days and warm the fluid during colder days.

Made to OEM specifications, this transmission oil cooler is equivalent to an OEM part. By replacing your transmission cooler preventatively, you can save your transmission from falling victim to premature failure.

- To ensure the best operation and longevity of your transmission cooling system, it is highly recommended that the standard high pressure hard line be upgraded to a soft line replacement, OE part# 52028920AI. Pressure surges in the system under heavy load while towing can cause transmission cooler leaks and failures. The upgraded rubber line reduces the effects of the pulses on the cooler unit.
