Derale Transmission Coolers

  • Stacked-Plate Cooler
  • Heavy-Duty Truck
  • With - 6 AN Inlets
  • Standard Mount
  • 13W x 7-5/16T x 2D Inch
  • Derale

13" Wide x 7-5/16" tall x 2" deep, super-efficient heat exchanger improves the performance and increases the lifespan of your vehicle's transmission. Includes -6 AN aluminum fittings and hose-barb adapters.


Features:

  • Prolongs life of transmission
  • Improves overall performance
  • Prevents heat-related failures
  • Most efficient cooling system with the large surface area of the stacked plate design and turbulator technology
  • Furnace-brazed aluminum construction for great heat dissipation
  • Comes with built-in mounting brackets for easy installation
  • Includes mounting kit, OEM spec hose with stainless steel clamps, Insta-dapt radiator adapter and brass hose-barb fittings


Specs:

  • Inlet size: -6 AN
  • Overall dimensions: 13" wide x 7-5/16" tall x 2" deep
  • Distance between inlets: 10"
  • Mounting dimensions: 5-3/4" tall x 12-1/4" wide

Note: The Derale Insta-dapt radiator adapter fits most vehicles with 5/16" transmission lines, but not all. In some cases, additional fittings or alteration of the OEM lines or hoses may be required for installation.


Stacked-plate heat exchangers have long been considered the most effective type of oil or transmission cooler, primarily because of their increased surface area. Allowing fluid to spread out over this larger surface area decreases the time required for heat transfer to take place. As a result, plate coolers typically manage to cool a greater volume of fluid faster than tube-and-fin, or even plate-and-fin, varieties.

This transmission cooler is a true game changer. We are now able to climb steep grades without overheating the transmission. Installation was fairly straightforward, and it fit in the same location as the original cooler. We have traveled over 4500 miles since installation and are very happy with its performance.


Comments
After one year this transmission cooler is working great. We have traveled over steep mountain grades with no problems.

I just received the Derale D13403 transmission oil cooler and the Firestone Ride-Rite air suspension system for my truck. I have not installed them yet but my experience with the ordering process was excellent. I placed my order on a Saturday afternoon and received confirmation of shipment later the same day. Everything was packaged very well and free delivery was quick. I have ordered from etrailer before and will continue to use them as my needs arise..

ordering was easy. Paula was professional, knowledgeable and helpful. The product arrived on time and was in excellent condition ready to install. Installation wasn't complicated just a few hours from start to finish. We are ready to roll!

  • Can a Transmission Cooler be Installed Vertically Instead of Horizontally
    Yes, the core in Derale transmission cooler # D13403 can be mounted so that the lines enter and exit from the side rather than the top. There is enough pressure in the lines to push the fluid through no matter how you choose to mount it! I have linked the installation instructions for you.

    We can definitely help. Since you are looking for a transmission cooler to replace what you have on your 2005 Acura MDX you would want to go with as large of a cooler as you can fit in the most efficient cooler style.

  • Do Transmission Coolers Have to Install Right Side Up Or Can they be Upside Down
    The Derale stacked plate transmission coolers like part # D13403 can be mounted in any orientation that you need including having the hose fittings down. The line pressure from the transmission will push all of the fluid through the cooler regardless of how it is mounted. My recommendation on mounting this transmission cooler is finding a location that maximizes air flow through the cooler. Ideally, this would be in front of the radiator or AC condenser. Either fitting style would work...

  • Best Transmission Cooler For 2019 Honda Odyssey
    The most efficient transmission cooler option for your 2019 Honda Odyssey is the largest transmission cooler that you can get to fit in front of the radiator. The second best placement is between the AC condenser and the radiator that allows for moderate air flow. The efficiency of a transmission cooler is based mostly off it's size and placement. I recommend Derale 19-Row Stacked-Plate Transmission Cooler Kit part # D13403 that measures 13" wide x 7-5/16" tall x 2" deep. The stacked-plate...

  • 2011 Chevrolet Avalanche Transmission Cooler Recommendation
    The Flex-a-lite Translife Transmission Cooler # FLX4126 that you ordered is pretty large at 20" wide x 10" tall x 3/4" deep. Your best option is going to be to go with a smaller cooler that is a more efficient style like the stacked plate Derale part # D13403 which measures 13" Wide x 7-5/16" tall x 2" deep so that you can fit both your factory and aftermarket cooler installed at same time.

  • How To Install A Transmission Cooler In Conjunction With A Factory Auxiliary Transmission Cooler
    In order to install the Derale 19-Row Stacked-Plate Transmission Cooler Kit part # D13403 in conjunction with your factory auxiliary transmission cooler on your vehicle, you have two options. You can install the cooler before the factory auxiliary cooler or after the factory auxiliary cooler. You will not need any additional parts to do so.

  • Where To Install Stacked-Plate Transmission Cooler
    The best location to install a transmission cooler is between the radiator and grille as this will allow the cooler to receive the most air flow. That said, you can still install the cooler between the radiator and engine and it will still work just fine but it won't be as efficient as when mounted in the other location as it will not receive as much airflow. The same holds true whether you are using a stacked or plate and fin style cooler although the stacked are more efficient by themselves....

The Transmission Cooler # D13502 that you referenced measures 11 inches wide by 7-1/4 inches tall. This is a pretty large cooler that should work well for you, but if you wanted to go slightly bigger and to an even more efficient design check out the Derale Stacked Plate Cooler # D13403.

  • Transmission Cooler Recommendation for a Hot Rod with a 454 BBC and Turbo 400 Transmission
    A lot depends on how much power you plan on producing with that big block and how big of a stall you are planning on using. Some stock 454's aren't crazy powerful, whereas others like the LS6 are very powerful. With that being said I would go with the absolute biggest cooler you can fit. Also, stacked plate coolers are the most efficient style so I would lean towards one of those as well. For example, the stacked plate cooler part # D13403 would do an excellent job for you so I would recommend...

  • Transmission Cooler for a 2009 Ford Expedition
    Transmission coolers such as # D13503 are not vehicle specific so you can install or have one installed that fits the space you have available in the engine compartment. If it were me though I would go with a stacked plate cooler, # D13403, because they are the most efficient and offer the most cooling. With that said check to see if your transmission system is a closed system. If it is then there will be no dipstick to check the transmission fluid. Instead there will be a cap over the...

  • How to Route Supplemental Transmission Cooler with Factory Cooler on Chevy Silverado
    The ideal setup is to run the fluid from the factory cooler, to the supplemental cooler, and then back to the transmission. This will keep the fluid as cool as possible. If you are worried about it being too cold like in the winter you would need to just let the truck idle to warm it up and then you will be good to go. Or the ideal solution is to use a thermostatic bypass that allows the cooler to be bypassed till the fluid reaches 180 degrees. For that you would need # D15719. Running...
