1986 Dodge Ram Pickup - Derale Atomic-Cool Remote Transmission Cooler Kit w/ Fan, -6 AN Inlets - Class V

12-3/4" Wide x 9-3/8" tall x 4-5/16" deep, remote cooler assembly features a high-efficiency, plate-and-fin heat-exchanger core with 500-CFM tornado fan for maximum airflow, ensuring optimum performance for your automatic transmission.


  • Improves performance and overall functioning of transmission
  • Has highly efficient, plate-fin cooler core for optimum heat transfer and minimum pressure drop
  • Offers superior airflow with 500-CFM, reversible tornado fan
  • Mounts anywhere with aluminum mounting brackets
  • Includes:
    • Complete cooler assembly
    • Aluminum AN fittings
    • Brass hose-barb adapters
    • 10' OEM spec hose with stainless steel clamps
    • Additional compression fittings
    • 180-Degree, in-line thermostat for power-saving fan shut-off
    • Insta-dapt radiator adapter
    • All necessary mounting hardware
  • Made in USA


  • Inlets: -6 AN
  • Adapters: -6 AN x 3/8" hose barb
  • Overall dimensions: 12-3/4" wide x 9-3/8" tall x 4-5/16" deep
  • Distance between inlets: 8-9/16"
  • Mounting dimensions: 4" tall x 11-5/8" wide
  • 1-Year warranty

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.

With a fan-mounted heat exchanger unit, you can be sure that there will always be optimum airflow for your engine oil cooler no matter where your cooler is mounted or what sort of environment you are traveling through. Couple that with the highly efficient, plate-fin core - wherein finned chambers provide increased surface area, allowing superior heat transfer with minimum pressure drop - and you have a truly effective heat-exchange system.

This system is ideal for late-model, electronic overdrive transmissions in which ensuring proper cooling and pressure maintenance is of the utmost importance.

Review from a similar Derale Atomic-Cool in Transmission Coolers

This is a good cooler however on a 4 wheel drive avalanche it's a challenge to get it installed in a position that will work with all of that equipment under there. I pinched the oring a little bit and it's leaking very slightly. On the next oil change I'll replace the oring, other than that this cooler works great. 479466

Review from a similar Derale Atomic-Cool in Transmission Coolers

Oil cooler works great, Only thing that I have an issue with is I can not use my stock oil filter with it. I have a 1992 Chevy K3500 with a 454 tonawanda 7.4 liter. In the instructions it is telling me to use a filter that is for a 350 or a 5.6 liter. But I was told by Derale that I should have no issues at all. 387448

  • Will a Derale Transmission Cooler Kit D13503 Work on a 2006 Nissan Titan Towing a 5th Wheel Trailer
  • The Derale Series 8000 Plate-Fin Transmission Cooler Kit, item # D13503, will provide extra cooling to help keep your transmission at normal temperatures when towing. Whether or not any cooler will provide enough cooling depends on many factors specifically related to your vehicle and trailer setup. I did a bit of checking on the 2006 Nissan Titan towing capacities and found that the 2006 Titan is rated for somewhere between 9,200 lbs and 9,500 lbs Gross trailer weight, properly loaded...

  • Where is the Best Place to Install a Remote Transmission Cooler on a 2017 Nissan Armada
  • As far as functionality there isn't one place that is really better than another for the Derale Atomic-Cool Remote Transmission Cooler Kit # D13950 on a 2017 Nissan Armada. Basically anywhere there is space for it will be a good location. On modern vehicles space in the engine compartment can be at a premium though so you will want to check ahead of time prior to installing a cooler. This cooler is 12-3/4" wide x 9-3/8" tall x 4-5/16" deep overall. The width and height probably won't...

  • Where to Install the Derale Atomic-Cool Remote Transmission Cooler Kit # D13950 on a Truck
  • What's great about a remote cooler with a fan like the Derale Atomic-Cool Remote Transmission Cooler Kit # D13950 that you referenced is that it can basically install wherever it will fit since the fan will provide all of the necessary airflow to cool the fluid. Here is what Derale says about mounting location for this cooler: The purpose of a remote mount cooler is to be able to mount the cooler away from the front of the vehicle therefore not blocking airflow to the radiator/condenser....

  • Stacked-Plate Transmission Cooler for 2018 GMC Acadia SLT with V6
  • Transmission and oil coolers are not vehicle-specific; you can essentially install any one for which you have the space available to install it. When it comes to coolers bigger is better. And if you want the best cooling even at lower speeds, such as when driving in mountainous areas, you might consider a remote-mount fan-powered cooler like the Derale Atomic Cool # D13950, an efficient plate-fin type cooler that will lower your transmission temperature even at low speeds since it does...

As long as you have room to install a Derale Atomic-Cool Remote Transmission Cooler, then it will work with your truck. These would be very good coolers for your application because they are high efficiency coolers with 500-CFM tornado fans. You will want to choose the correct transmission cooler for your vehicle based on the size of...

  • Transmission Cooler with Fan Recommendation for a 2003 Chevy Silverado
  • When you install the Derale Atomic-Cool Remote Transmission Cooler Kit w/ Fan # D13950 that you referenced you can either replace your current cooler or you can install this one after the factory cooler so that you get the cooling power of both. The most common and recommended method would be to put this cooler down stream of your factory cooler so that is what I would recommend for you. All you would need is the cooler and the fitting part # D13035 and you would be good to go. The...

  • Transmission Cooler Kit Recommendation for 2012 Chevrolet Silverado 1500, 5.3L Engine
  • For your situation, the best, most-effective transmission cooler I can recommend for you is the Derale Atomic-Cool Remote Transmission Cooler Kit with Fan # D13950. You will also want to use the Derale Snap-In Radiator Adapter Fitting for GM # D13035, so you do not need to flare lines for installation. When driving in the city, easy and abundant air flow to the factory or aftermarket transmission cooler is not as available as when driving on a flat, open highway. The # D13950 cooler...

  • Will the Derale Atomic-Cool Transmission Cooler Fit on a 2009 Silverado 1500 Z71 4WD
  • The ideal operating temperature for transmission fluid should remain between 160 and 200 degrees. If your transmission fluid was reaching 195 degrees when towing your fifth wheel trailer, it would be a good idea to either upgrade your factory added cooler or add an additional transmission cooler because this temperature could increase if you are towing on in hot weather or through hills where the engine and transmission will be working harder than on flat ground. Installing a remote...

  • Can a Transmission Cooler Bypass the Factory Cooler on a 2007 Nissan Pathfinder
  • A lot of people with Nissan vehicles are looking to bypass the factory cooler contained in the radiator like on your 2007 Nissan Pathfinder. The coolers we carry are designed to supplement the factory cooler although some people have used them to replace the factory cooler. You would want to go with the largest cooler possible if you bypass the factory cooler and the inlet/outlets on the radiator for the factory cooler will have to be plugged. Or instead of the largest cooler you would...

  • Recommendation for a Supplemental Transmission Cooler for a 2007 Ford F-150 with 5.4 Liter Engine
  • Based on the information you have provided, which I greatly appreciate, a standard supplemental cooler should be sufficient for your needs. Ideally you want the transmission temperature to be no more than 200 degrees F. Mounting a larger cooler directly behind the grille (in front of everything else) such as # D13504 should get you to the ideal range. You will also want fitting # D13025 so you will not have to cut and flare any lines. A remote cooler with its own fan will provide the...

  • Do Inlet And Outlet Ports Need To Be Mounted In A Particular Direction On Derale Cooler, # D13950
  • The ports on the Derale Atomic-Cool Remote Transmission Cooler Kit w/ Fan, # D13950, do not need to be mounted in any particular direction. The transmission cooler is not directional so having the inlet on the top or bottom does not matter. You will want to choose the inlet or outlet port location by what will make your installation easier. Since this cooler comes with a fan-mounted heat exchanger you can mount the exchanger wherever you want because the fan will provide optimum airflow.

  • Compatibility of Derale # D13950 Atomic-Cool Remote Mount Transmission Cooler with 2012 Yukon XL.
  • As long as you have the available space in the area where you want to install the cooler, you can certainly use the # D13950 Atomic Cool Transmission Cooler on your 2012 Yukon. Keeping the transmission cool when you're moving in stop-and-go traffic is exactly what this particular cooler is designed for. The # D13035 you already have is the recommended fitting. You'll want to install the cooler in the return line heading back to the transmission, whether that line's coming from the radiator...

  • Remote Transmission Cooler Recommendation for a Chevy Silverado 2500HD
  • The transmission coolers that we carry are meant as supplemental coolers anyway so they will work great for what you want to do. The path of the fluid will start at the transmission, go to the factory cooler, then to the supplemental cooler, and then back to the transmission. For a remote cooler that includes the mounting hardware you can use # D13950. I have included a link to the installation details for you. I have also included a link to our FAQ article to the right on transmission...

  • Remote Transmission Cooler Recommendation for a 2001 Dodge Ram
  • The Derale Atomic-Cool Remote Transmission Cooler Kit w/ Fan # D13950 would actually be perfect for what you are looking for. The fan will provide the cooler with the needed air flow to reduce the temperatures and the plate and fin construction of this cooler makes it very efficient. You would see a noticeable reduction in transmission fluid temps. You also would want to install this after the factory cooler to get maximum gains.

  • How to Determine Which is the Return Line on the Factory Transmission Cooler of 2006 Chevy Equinox
  • I can tell you an easy way to figure out which line is the return line and which is the feed line on the transmission cooler of your 2006 Chevy Equinox. When your car is cold go out and start it up and put it in drive for 10 seconds. Now put it back in park and shut it off. Go out and feel both coolant lines, the cooler of the two is the return line. The installers use this trick here all the time. I attached a couple FAQ articles on transmission coolers for you to check out also.

  • Transmission Cooler Options and Installation for a 2009 Chevy Equinox Pulling a 2,800 Pound Trailer
  • I am not sure what, if any, benefit new cooler lines would offer. But the right transmission cooler will do the trick. If your 2009 Chevy Equinox has the 3.4 liter engine, we have several options. I recommend the Derale Transmission Cooler, # D12901. This has the simplest, tube fin design. It is fairly small so it should be easy to find the best mounting point. There are essentially three places to mount a transmission cooler. The best place is between the grille and AC condenser...

  • Transmission Cooler for a 2017 Hyundai Tucson
  • Most cars, light trucks, and SUV's nowadays have either 3/8" or 11/32" transmission lines. I was not able to find the exact size transmission line for your 2017 Hyundai Tucson but the Derale Atomic-Cool Remote Transmission Cooler Kit part # D13950 comes with adapter fittings that will work with 5/16", 3/8", and 11/32" transmission lines. As long as you have 12-3/4" wide x 9-3/8" tall x 4-5/16" deep of space to mount this cooler anywhere on the vehicle, then it will work well for you.

  • How to Select Best Transmission Cooler for 2012 Chevy Silverado
  • The best transmission cooler for your 2012 Chevy Silverado is going to be the largest one that fits. A unit with a fan will give your truck optimum cooling power, but you do need to measure to ensure that you have enough room for this type of cooler to fit because a unit with a fan will take up more room. For example, the Derale 16-Pass Electra-Cool Remote Transmission Cooler # D15900 measures 15-3/4" wide x 11-1/2 " tall x 5" deep so you would need to find that amount of space under...

  • Bypassing Factory Transmission Cooler on a 2006 Ford F-250 with 5.4 Liter
  • If the chamber walls inside the radiator that separate the transmission cooling portion with the coolant portion have cracked, ruptured, or are otherwise leaking then you would have to either replace the radiator or plug up the transmission fluid inlet and outlet ports on the radiator and instead use a supplemental cooler as the main cooler. In this situation I recommend a remote cooler such as # D13950 that will have its own fan. That way you are ensured to get the optimum amount of...

  • Transmission Cooler Recommendation for Jeep Grand Cherokee that Does Low Speed Off-Roading
  • I would highly recommend a transmission cooler for your 2000 Jeep Grand Cherokee. Since you will be doing low-speed off-roading I would recommend a kit that comes with a fan so that you can ensure the cooler gets air-flow like the Derale Atomic-Cool Remote Transmission Cooler # D13950. This comes with everything needed to install including lines and fittings but to make installing the cooler easier you would want the radiator adapter part # D13034 to prevent you from having to go through...

  • Best Transmission Cooler for a 2012 Chevrolet Silverado 1500 with 6.2L V8 Enigne
  • For a transmission cooler that will work well in your 2012 Chevrolet Silverado 1500 with the 6.2L V8 engine, I recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13504. The Derale Series 8000 is going to install in front of the ac condenser and behind the grille. It is 11" wide x 12" tall x 7/8" deep which is plenty for your transmission so long as you are on the open road and not in a lot of stop and go traffic. If you do find yourself in a bunch of stop and...

  • Best Transmission Cooler for Off-Roading in a 2007 Toyota FJ Cruiser in Year-Round Warm Climate
  • The Class rating applied to transmission coolers is to help simplify choosing a cooler for a vehicle. Basically you would think about it in terms of a hitch class rating. So for example if your 2007 Toyota FJ Cruiser has a Class III hitch then a transmission cooler shown as a Class III is a good match. But ultimately you can use any cooler that fits in the intended mounting location. Derale transmission cooler # D13503 is a very popular option. It is a Class III but if you want something...

The core on this cooler has 6 AN fittings. This cooler does not come with a thermostat but one can be added using # D13021. You will also need a mounting kit such as # D13002, hose clamps such as # D13008, and hose # D13017. The other option is a remote cooler that comes with...

  • Remote Mounted Transmission Cooler for 2002 Ford F250 with 7.3L Diesel
  • If you do not have the necessary space directly behind the grille, a remote mount cooler with a fan would be your best bet for maximum cooling efficiency. A stacked plate cooler/ fan combo like part # D13950 offers a good balance between performance and relatively small size. You will want to mount the cooler in a protected location that has sufficient air flow to allow the fan to push air through the cooler. Ideally, you want to see your transmission cooler temperature below 200 degrees. For...

  • Reducing Transmission Heat When Towing with 2008 GMC Yukon Hybrid
  • I checked the online owner's manual for the 2008 GMC Yukon hybrid and on page 4-22 it notes that the maximum loaded trailer weight this vehicle can tow is 6200-lbs (if 2WD) or 6000-lbs (if 4WD). If your unloaded trailer's dry weight is 6700-lbs then the vehicle may well be heating up from being overloaded. You might check your printed manual just in case it has different information about towing capacity. It is not possible to add towing capacity to a vehicle by installing aftermarket...

  • Recommended Supplementary Transmission Cooler for 2004 Dodge Dakota
  • Transmission fluid temperature can rise quickly when towing, especially in warmer weather and when towing on uphill grades which naturally mean slower speeds and reduced air flow to your Dakota's cooling system. Supplementary coolers are a wise addition to a towing vehicle, and so too is keeping your transmission fluid fresh as you have done. Standard passive coolers like Derale # D13503 (along with hose fitting kit # D13030) can install in front of your AC condenser to give you more...

  • While you can technically install the Derale 20" Dual-Pass Heat Sink Transmission Cooler # D13265 in your vehicle that already has an Atomic-Cool Remote Transmission Cooler like # D13950 and another aftermarket oil cooler, it is not recommended. Additionally, there should not be a need for additional cooling considering what you already have; if your transmission temperatures are still too high it may be a good idea to have the transmission loooked at.
