DIESELSITE 2003-2007 Cummins 5.9L Transmission Filter System for Automatic 1/2 Lines

The Dieselsite External Transmission Filter System (TFIKD) provides superior filtration for Dodge automatic transmissions from 2003-2007 with the 5.9L engine. Unlike internal OEM filters that only catch large particles on the suction side of the pump, this kit installs an efficient 22-micron filter on the "push" side of the pump, ensuring all fluid is cleaned before returning to the pan. This design keeps your valve body clean, maintaining optimal transmission shift quality. The kit features stainless braided high-pressure hoses and OEM-matching fittings for easy, cut-free installation and quick filter changes. An internal bypass valve set at 25 psi prevents fluid restriction if the filter becomes dirty, ensuring continuous lubrication. The filter canister also acts as a "mini" cooler, helping to dissipate a small amount of heat. This system is designed to protect your transmission in case of torque converter failure by capturing debris before it can recirculate. With the Dieselsite kit, pan drops for filter changes become nearly obsolete, with the OEM filter only requiring service every 100,000 miles. An optional pressure gauge allows for monitoring filter condition, and the unit supports the addition of a transmission flush valve for easier torque converter purging.
