Derale Transmission Coolers - D12906

  • Tube-Fin Cooler
  • Small SUV
  • 13W x 7-1/2T x 3/4D Inch
  • With 11/32 Inch Hose Barb Inlets
  • Derale
  • Standard Mount

13" Wide x 7-1/2" tall x 3/4" deep, reliable, all-aluminum tube-and-fin cooler extends the life and improves overall functioning of your vehicle's transmission.


Features:

  • Improves functioning and overall performance of transmission
  • Extends life of transmission and prolongs period between necessary fluid changes
  • Cuts down on heat-related failures
  • Agitates fluid with built-in, embossed turbulators for more efficient cooling
  • Constructed of durable, lightweight aluminum
    • Thermal-conductive metal provides excellent transfer of heat
  • Includes:
    • High-temperature, OEM spec hose with stainless steel clamps
    • Nylon mounting rods
    • Insta-dapt radiator adapter
  • Recommended for small to mid-size trucks and SUVs
  • Imported


Specs:

  • Inlets: 11/32" hose barb
  • Overall dimensions: 13" wide x 7-1/2" tall x 3/4" deep
  • Core width: 10-1/8"
  • Distance between inlets: 6-1/4"
  • 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.


Perhaps the simplest type of heat exchanger, the tube-fin effectively cools a variety of automotive systems. The concept is simple: Fluid cools as it travels through the core by transferring heat out to the fins. The fins then provide the surface area necessary for sufficient heat exchange to take place, allowing the heat pulled from the fluid to dissipate into the surrounding air. Quick, easy and effective.

  • Recommended Transmission Cooler For A 2016 Honda Pilot
    Hello Doug, thanks for reaching out. When selecting a transcooler, if you want the most effective cooling, you will want to get the largest cooler available for your vehicle. Basically more surface area means better cooling, and we do not always go by the class designation. Our best option for the 2016 Honda Pilot the Derale Dyno-Cool Tube-Fin Transmission Cooler Kit - Class II # D12906. This cooler is 13" Wide x 7-1/2" tall x 3/4" deep which is the largest we offer for your car. This comes...

  • Trailer Hitch, Ball Mount kit, Trailer Wiring, and Transmission Cooler for a 2007 Toyota Sienna
    I can certainly make some recommendations for a towing set up on your 2007 Toyota Sienna. Starting with a trailer hitch, the most popular hitch for your vehicle is Draw-Tite # 75237. This is a Class III hitch rated for 4,000 pounds gross trailer weight, 400 pounds tongue weight. The trailer you plan to tow is right at this limited. If there is any way you can reduce the weight of the trailer some, it would be more ideal. I have included a link to the installation details and a video showing...

  • Transmission Cooler for 2017 Ram 1500
    The Derale Series 6000 cooler part # D12906 would work on your 2017 Ram 1500. For a truck I wouldn't' recommend this as my first choice as it's a little on the smaller size and not the most efficient of designs. Instead I would have recommended something like the # D13503 which is much more efficient at cooling.

  • Will Flex-a-lite Direct Fit Transmission Cooler Fit the 2016 Toyota 4-Runner 4x4
    If your 2016 Toyota 4Runner is 4.0L V6 Engine - 246 C.I. - 4WD, this Derale Dyno-Cool tube fin transmission cooler, part # D12906, is confirmed to fit. This transmission cooler kit provides additional cooling to protect your transmission. Cooler transmission oil gives more reliable, consistent shifts under racing conditions and prevents transmission damage under extreme towing conditions. The overall dimensions are 13" wide x 7-1/2" tall x 3/4" deep.

  • Transmission Cooler Recommendation for a 2005 Acura MDX Towing a 3,750 Pound Boat and Trailer
    The Class of transmission cooler you use will depend more on where you can mount it. The most efficient place is in front of the AC condenser. You could then use a Class I cooler, like # D12901. If mounted behind the condenser, I would go with a Class II like # D12906. If mounted behind the radiator I would go with a Class III like # D13502. The problem is that the further away from the front of the vehicle a cooler is mounted, the less airflow it receives. The less airflow a coolers...

  • Could a Fairly Handy Person Install a Transmission Cooler on a 2001 Dodge Grand Caravan
    A fairly handy person could install a transmission cooler onto a vehicle pretty easily. I have installed a cooler on two of my cars without a problem and I consider myself fairly handy. I attached an installation video of a transmission cooler being installed onto a vehicle to give you an idea of what it is like. Most vehicle will not require the removal of the front end like the vehicle in the video, so do not let that discourage you. I also attached an FAQ article on transmission coolers...

  • Will Using Weight Distribution System Improve Engine Performance on 1989 Toyota 4Runner When Towing
    The main purpose of a weight distribution system would be to reduce sway and the strain on rear suspension, as well as improve steering, when towing your Vintage travel trailer with your 1989 Toyota 4Runner. Using a weight distribution system really is a great idea but it would not have any affect on the performance of your engine. I have included an article which covers common weight distribution and sway control questions. When it comes to performance of your 4Runner, one recommendation...

  • Transmission Cooler Recommendation for a 2008 Honda Pilot
    The main differences between the available transmission coolers is the style of the coolers and the size. There are style that are more efficient that others, and obviously the bigger the cooler the more efficient it is as well. The tube-and-fin style has a tube that carries the transmission fluid through the cooler. It is also distinguished by its turbulators, which agitate the fluid to get more of it to contact the aluminum in the tube. Aluminum fins are attached to the outside of the...

  • Transmission Cooler for 2007 Jeep Grand Cherokee
    The Derale # D12906 is a universal-fit aftermarket part that will fit your 2007 Grand Cherokee if the space behind the grille and in front of the A/C condenser and radiator can accommodate its 13 by 7-3/4 inch dimensions. If the available space is to small to allow installation of the D12906, we have smaller plate-fin style coolers like part # D13502 that are actually more efficient at cooling your transmission fluid. This cooler would typically be installed so it would be last in line...

  • Recommended Transmission Cooler for a 2000 Buick Century
    A class I or class II transmission cooler should work well for your needs. I recommend class I transmission cooler # D13101, or a class II cooler like # D12906 would also work to help with the issue you are having during warm weather. Both of these Derale coolers are designed to cool very efficiently and install easily, and either one would be a good choice for your 2000 Buick Century. In addition to the transmission cooler, you would also need the custom fittings # 41418 to match the...

  • Best Rear Hitch Options 2016 Montana High Country 362RD 5th Wheel
    You could go with the Lippert 2" Trailer Hitch Receiver for Campers and Trailers # LC730647 you were looking at, but because this only hitch has a 300-lb tongue weight rating I believe there is a better solution. I recommend going with the Curt Adjustable Width Trailer Receiver # 13703 , because it has a slightly higher 350-lb tongue weight capacity. You'll want to measure the frame width on your Keystone Montana High Country 362RD to make sure that it isn't wider than 72", but as long...

  • Recommended 7-Way Connector And Trailer Hitch Receiver For 2014 Honda Odyssey
    I would be happy to help you get set up with all of the components you will need to tow an ultra lite RV trailer with your 2014 Honda Odyssey. Starting with the trailer hitch receiver the Curt Trailer Hitch Receiver # C13068 is a great option which offers a maximum tongue weight rating of 350lbs and maximum trailer weight rating of 3500lbs. Keep in mind that your 2014 Honda Odyssey can only tow up to 3500lbs with 2 passengers and requires a transmission cooler to be installed. Since the...

  • Transmission Cooler for 2012 Subaru Outback 2.5i W/CVT Transmission.
    If the CVT transmission has cooling lines running from the transmission to the radiator (some do, some don't), you can install a transmission cooler. A transmission cooler is an effective and inexpensive insurance policy for your transmission, especially if the trailer you'll be towing is close to the towing capacity of the vehicle or if you'll be towing in mountainous or hilly terrain. If your transmission does have lines, we recommend getting the biggest cooler that will fit in the available...

  • Transmission Cooler and Thermostat for a 2011 Subaru Forester
    Transmission fluid cannot be overcooled. But in the winter when the weather is cold you would either need to let your 2011 Subaru Forester warm up a little longer or you can install a thermostat with the cooler so that it will only send fluid through the cooler once the temperature is high enough. You can use Derale Fluid Control Thermostat Kit w/ 3/8" NPT Ports Item # D13011 with mounting bracket kit # D25793. The fluid will bypass a cooler, such as # D12906, if the fluid temperature...

  • Transmission Cooler Recommendation for a 2005 Nissan Pathfinder 4X4 SE and 6K Trailer
    For a trailer weighing 6,000 pounds I recommend going with a stacked-plate cooler because they will be the most efficient and will provide the best cooling compared to the other cooler options. For a kit you can use # D13403. For the best cooling you can get a cooler that comes with its own fan like # D13950. This will provide the optimum cooling no matter where the unit is mounted. I have included a link to our FAQ article on transmission coolers for you.

  • Recommended Derale Transmission Cooler for 2012 Toyota RAV4 with 3.5L V6 Engine
    Adding a supplementary transmission cooler to a vehicle that tows a trailer is a great way to reduce the thermal stress on the transmission. For your 2012 Toyota RAV4 with the V6 engine the most popular cooler is the Class III Derale # D13503, and this also happens to offer the highest cooling efficiency of all such products available for your RAV4. This is a complete kit with all needed parts. I linked a couple of help articles on the topic of transmission coolers.

  • Does a Transmission Cooler Need A Thermal Bypass for Sub-Freezing Weather
    I have not ran into any issues where there was a thermal bypass needed for below freezing temperatures when using the Derale Dyno-Cool Tube-Fin Transmission Cooler part # D12906. There is a lot of heat generated when all of the parts get moving in there and a cool transmission is a happy transmission. I can't see the cooler over cooling the fluids to a point that there would be any negative effects. For your power steering I rarely see the need to cool it. Even when hauling a trailer you...

  • Secondary Transmission Cooler For A 2000 Honda Accord V6 Needed
    The best way to select the correct transmission cooler is by determining where there is enough space to mount it. The attached diagram shows the best three positions to mount the transmission cooler in order. Transmission coolers are more efficient when they receive maximum air flow. The "A" transmission cooler location in the diagram is 100% efficient so a larger transmission cooler is not needed to compensate for the loss of cooling power.

  • 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...

  • Installation of Derale Transmission Cooler # D12906 on a 2003 Acura MDX
    A transmission cooler will attach in-line with the transmission fluid return line on your 2003 Acura MDX. The best way to determine which line on a transmission cooler is the return line from the radiator is to use the following procedure: 1. Start engine while engine is cold 2. Place transmission shift lever in drive for no more than 10 seconds. 3. Stop engine and remove keys 4. Identify the transmission fluid return line by feeling both lines. The coolest line is the return line. You...

  • Transmission Cooler Recommendation for 2012 Toyota RAV4
    For your 2012 Toyota RAV4 the Derale cooler part # D12906 would be a great option. We normally recommend going with the largest cooler that will fit in front of the radiator. In the case of this cooler it measures 13" Wide x 7-1/2" tall x 3/4" so you would need to measure the available room you have. A more efficient cooler that's a bit smaller is the part # D13503 which measures 11" Wide x 8-3/4" tall x 7/8" deep.
