The Power Driven 22001211005 is a 48RE Transmission Cooler Line Replacement Kit for 2003-2007 Dodge 5.9L 24V Cummins trucks - a complete hose-and-fittings solution for 3rd Gen owners dealing with leaking or damaged factory transmission cooler lines. This kit replaces the full factory steel line circuit with 1/2" ID rubber-coated hose and all necessary fittings, maintaining OEM routing from the transmission through the heat exchanger on the driver's side of the engine and on to the air-to-oil cooler in front of the radiator. The 22001211005 fits the 48RE specifically; if your truck is a 1996-2002 with a 47RE, the 47RE kit is the correct option.

Buy this if...

Your 2003-2007 Dodge Ram has a 48RE automatic with leaking or failing factory cooler lines.
You want a complete, USA-made kit - hose, fittings, and clamps - without sourcing components individually.
Your build includes an aftermarket 1989-2002 heat exchanger with non-standard ports (adapter included).

Do not choose this if...

Your truck is a 1996-2002 with a 47RE - see the 47RE cooler line kit.
Your truck is a 1994-1995 with a 47RH - a separate kit covers that application.
Your cooler circuit has been relocated or modified - a fittings-only kit is available for those builds.

Verify before ordering...

Confirm your transmission is the 48RE - the 47RE (1996-2002) requires a different kit.
Confirm your cooler circuit routing is stock or stock-path compatible.

The Right Kit for Your 48RE Cooler Line Repair

The factory steel transmission cooler lines on the 2003-2007 48RE corrode and develop leaks at fittings over time - and sourcing a complete matched replacement has historically meant hunting down individual components. The Power Driven 22001211005 solves that with one order: pre-cut 1/2" ID hose, all fittings for the full circuit, and premium rubber-coated clamps for a clean, finished installation. If your 3rd Gen Cummins 48RE is leaking at the cooler lines, this is the correct kit to order.

Note the routing difference from earlier kits: on the 48RE, the heat exchanger is on the driver's side of the engine - not the passenger side. The kit is designed for this routing specifically. An adapter for non-standard ports on aftermarket 1989-2002 heat exchangers is also included. Confirm your transmission code and routing path, then proceed with confidence.

Made in USA: Hose manufactured and rated in the USA

Hose Rating: 300F and 300 psi - purpose-built for transmission cooling

Real-World Tested: 100,000 miles over 5 years on a built Cummins tow rig

Fitment-Specific: Engineered for 2003-2007 48RE - not a universal kit

Why Hose Quality Matters on 48RE Cooler Lines

Power Driven's testing found that generic transmission hose - including typical auto parts store options - frequently fails in this application within a couple of years. The 1/2" ID hose in this kit is USA-made, rated to 300F and 300 psi, and has been validated across 100,000 miles on a hot-rod Cummins tow rig with a built transmission over five years without incident. The same hose is also available by the foot for custom applications.

For stock-routing 48RE cooler line replacement on a 2003-2007 5.9L 24V Cummins, if your year and transmission match, this is the part to order.

48RE Fitment - 2003-2007 5.9L 24V Cummins

This kit fits 2003-2007 Dodge Ram 2500 and Ram 3500 trucks equipped with the 5.9L 24-valve Cummins engine and 48RE automatic transmission. All model years in this range use the same 48RE and are covered by this kit.

2003 Dodge Ram 2500 / 3500 - 5.9L 24V Cummins - 48RE
2004 Dodge Ram 2500 / 3500 - 5.9L 24V Cummins - 48RE
2004.5 Dodge Ram 2500 / 3500 - 5.9L 24V Cummins - 48RE

2007 Dodge Ram 2500 / 3500 - 5.9L 24V Cummins - 48RE

Vehicle or engine modifications may affect fitment. Confirm your cooler circuit is stock-path compatible before ordering.

Avoid These Common Mistakes

48RE vs 47RE - Different Kits:
The 48RE (2003-2007) and 47RE (1996-2002) are different transmissions with different cooler line kits. Ordering the 47RE kit for a 3rd Gen 48RE truck is the most common wrong order on this product family. Verify your transmission code before purchasing.

Heat exchanger side: The 48RE routes to the driver's side - earlier kits route to the passenger side. Do not mix kits across transmission generations.
Using generic auto parts store hose: Standard transmission hose commonly fails in this application within a couple of years. This kit's hose is rated to 300F and 300 psi.
Modified cooler circuit routing: If components have been added, relocated, or removed from your circuit, the standard kit may not match. The fittings-only kit is available for those applications.

Order Checklist

Transmission confirmed as 48RE (2003-2007 5.9L 24V Cummins)
Not ordering the 47RE kit by mistake - different transmission, different kit

Fittings-only kit noted as alternate for modified circuit builds

For a 2003-2007 Dodge 5.9L 24V Cummins with a 48RE automatic and standard cooler circuit routing, the Power Driven 22001211005 is the correct complete replacement kit to order.

Frequently Asked Questions

Click or tap a question below to expand the answer.

Will this kit fit my 2003-2007 Dodge Ram 5.9L Cummins with a 48RE?

Yes - the Power Driven 22001211005 is designed specifically for 2003-2007 Dodge Ram 2500 and 3500 trucks with the 5.9L 24-valve Cummins and 48RE automatic transmission. It covers all model years from 2003 through 2007, including the 2004.5 mid-year. It does not fit the 47RE (1996-2002) or the 68RFE found in later 6.7L Cummins trucks.

What is the difference between the 48RE and 47RE cooler line kits?

The 48RE and 47RE are different transmissions with different cooler line routing - they are not interchangeable kits. The 47RE was used in 1996-2002 Dodge Cummins trucks; the 48RE replaced it in 2003 and ran through 2007. One key physical difference: the 48RE routes the heat exchanger to the driver's side of the engine, while earlier setups used the passenger side. If your truck is a 1996-2002, the 47RE cooler line kit is the correct option.

Does the kit include everything I need, or do I need to buy anything separately?

The 22001211005 includes all necessary fittings, pre-cut 1/2" ID hose, premium rubber-coated clamps, and an adapter for non-standard aftermarket heat exchanger ports. Nothing needs to be sourced separately for the core factory-routed cooler line replacement. If your cooler circuit has been modified - components added, relocated, or removed - Power Driven offers a fittings-only kit for those applications.

My 3rd Gen Cummins is leaking transmission fluid - is this the right kit?

If the leak is originating from the factory steel transmission cooler lines on a 2003-2007 48RE, this is the correct replacement kit. Power Driven developed the 22001211005 specifically to address leaking or damaged factory cooler lines on this application. Confirm the leak source is the cooler lines themselves - not a transmission fitting or cooler end-tank - and verify your routing is stock-path compatible before ordering.

Does this kit work with an aftermarket heat exchanger on a 3rd Gen?

Yes - this kit includes an adapter for non-standard ports on aftermarket 1989-2002 heat exchangers. If your heat exchanger has been fully relocated or your cooler circuit has been otherwise heavily modified, confirm your routing is compatible with the standard kit layout or consider the fittings-only kit instead.

Does this kit fit the 2004.5 Dodge Ram with the 48RE?

Yes - the 2004.5 Dodge Ram with the 5.9L 24V Cummins and 48RE automatic is explicitly listed in the fitment coverage for this kit. The 22001211005 covers the full 2003-2007 48RE range including both the 2004 and 2004.5 model year variants.
