Mopar Transmission Cooler Line Jumper Tube for Ram (2019-24) 2500/3500 6.7L Cummins 68RFE

This genuine Mopar jumper tube is part of the transmission oil cooler line system on 2019–2024 Ram 2500 and 3500 trucks with the 6.7L Cummins diesel and 68RFE automatic transmission. It is the OEM automatic transmission oil cooler tube that links the cooler and main line assembly, routing fluid through the factory cooling circuit.

Built as a pre-bent steel hard line with the correct flare ends and brackets, the 68322506AB jumper tube follows the original routing path to maintain clearance around the radiator support, frame, and suspension. Using the proper Mopar tube helps ensure leak-free connections and proper line support on daily driven work trucks and heavy towing rigs that rely on the 68RFE to stay cool under load.

This part is the updated replacement for earlier jumper tube number 68322506AA, providing current-production fitment and materials. Installing the correct OE tube avoids the kinks, stress points, and sealing issues that can occur with universal line repairs or poorly bent aftermarket pieces, which may restrict flow and contribute to higher transmission temperatures over time.

Whenever the cooler is replaced, lines are repaired, or the original jumper tube shows signs of corrosion, impact damage, or deformation, replacing it with this Mopar assembly is a straightforward way to restore the integrity of the cooling circuit. The line is designed to work with the rest of the OEM 68RFE cooler plumbing, including the main line assembly and integrated bypass block used on late-model Ram HD trucks.

For owners and shops maintaining 2019–2024 Ram 2500/3500 6.7L Cummins trucks, using the 68322506AB jumper tube ensures OE-level fitment and helps keep transmission fluid flowing properly through the cooler, supporting long service life and consistent performance in demanding conditions.
