Description
XDP carries the Full Send Diesel FSDDRPINHE0309CU Billet Transmission Heat Exchanger that can help resolve the issue with the transmission in your 2003-2009 Dodge 5.9L/6.7L Diesel. This billet heat exchanger offers all the benefits of efficient heat transfer and cooling while ensuring reliability by eliminating the possibility of failure and cross-contamination of the engine coolant & trans fluid. This heat exchanger is a plug-and-play solution and is compatible with a completely stock truck while requiring no additional hardware. To install, simply replace your stock heat exchanger with this thoroughly engineered billet heat exchanger.
The motivation for developing this billet heat exchanger stems from numerous experiences with factory exchangers failing internally. Such failures result in the unfortunate mixing of engine antifreeze with transmission fluid. This often leads to transmission damage and contaminating the truck's cooling system with a troublesome milky red fluid. Neglecting to properly flush the coolant and transmission fluid from the coolant system can ultimately cause engine failures as well.
This heat exchanger is precision-cut from a solid block of aluminum, featuring coolant passages on one side and transmission fluid passages on the other. No welded seams or tubes means that this heat exchanger will never fail over time. FDS stands behind this product with a 100% guarantee that cross-contamination will not occur under any circumstances.
Do you need a heat exchanger? Why not just bypass it?
These are common questions that FSD encounters daily and regrettably, there is no one-size-fits-all answer to this query. In any climatic condition, the presence of a heat exchanger proves to be beneficial. In warmer climates, it serves to cool the transmission fluid, while in colder circumstances, it aids in warming the transmission fluid.
The Dodge trucks were originally equipped with a heat exchanger for a purpose, and FSD firmly believes in their considerable advantages. As long as the heat exchanger doesn't fail, causes transmission damage due to inherent flaws in the factory design. With this heat exchanger now available in the market, FSD has successfully addressed this significant drawback, effectively eliminating any potential issues or problems.
How does the heat exchanger work?
Unfortunately, there is a lot of misunderstanding about heat exchangers because people don't understand how they work. In short, hot engine coolant runs through one side, and transmission fluid runs through the other side. In hot climates when the transmission fluid temperature exceeds the engine coolant temperature, the heat from the trans fluid will be absorbed into the cooling system thus being cooled off through the radiator. In cold climates, the engine coolant helps warn up and maintain correct transmission fluid temperatures by absorbing heat from the engine cooling system.
What's Included?
Everything you need for installation is Included. Simply remove your stock heat exchanger and swap it out for our billet heat exchanger, then top off fluid as needed. Works with stock coolant and transmission lines or any of FSD's -AN braided hose kits.

It's a pretty looking piece of art. I don't know if I want to install it or use it as a necklace. I'm sure it operates like a workhorse. I'm very happy with it. I haven't installed it yet, until this coming Thursday from a certified mechanic. I want it installed right, it's a beautiful piece of equipment and it should have the only the best installation.

Not as simple as the description says.

The product is very good. The shipping was fast, transaction was easy. That's where the easy stops. Don't let the description fool you. This thing is a royal pain in the ass to replace, and that's from someone with all the right tools and 40 years experience working on my own vehicles. Your stock heat exchanger is mounted to a bracket which is mounted to the block. It's secured to the bracket by bolts which come through the back of the bracket, and the stock unit is secured by 10mm nuts. For some reason, full send diesel opted to not drill all the way through the baseplate which would make this job a lot easier. Instead, it's only drilled and threaded about 1/2 way through, making it necessary to either drill it the rest of the way or remove the stock unit, then remove the bracket. Once you get the bracket off (two bolts in the block and another through the bell housing), if you're like me you discover the stock bolts are too long to work. Since new ones aren't included, a trip to the hardware store to match up some bolts that would work was necessary. Then there's the fun of trying to fit the new unit back in with the bracket attached. Also, if you're going to do this job, replace the hoses. Fair warning, removing the one running to the drivers side of the engine block is a huge pain all by itself. Don't think about ordering the preformed OEM hoses. They're around $175 for the pair, and are back ordered for about 90 days. To clarify, this isn't a rant against XDP. They are fantastic. But full send needs to change their description, and make sure the needed hardware is included in each package. That's on them, not their vendors.
