Derale Transmission Coolers - D12906

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

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 Ford Maverick'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.

I was able to install this and the PS cooler in one afternoon. I am not a mechanic, but I am fairly handy. Your milleage may vary. All the parts were correct and fit my 2007 Honda pilot fine.



by:

hose provided could have been a little longer, but overall product was a good fit for our Honda Odyssey



by:

A simply outstanding experience. Great prices and customer service. Outstanding support with the web site videos. A true pleasure to deal with these folks.



by:

This is a great product and it is priced better than anywhere else that I could find. The shipping was extremely fast and the product was packaged well - I know it will help in my towing on my Tahoe



by:

Easy install, works great. Installed on a 2001 Jeep Grand Cherokee. I tow a 19' boat and haven't had any transmission issues since.



by:

Good reliable cooler and really good shipping and tracking!



by:

Have not installed yet but the product looks great. Etrailer.com's service is so fast it's amazing. Dealt with them before and will not hesitate to deal with them again in the future. Great company.



by:

The tranny cooler was really simple to install. Everything you need is in the kit.It took about 45 minutes.
Great product. Delivery was quick.
Thanks to all, no picture at this time, trucks on the road.



by:

Great for the money free shipping anytime you are pulling a heavy load you should always have this



by:

I ordered this cooler for my daughter's 2012 Nissan Rogue to fix CVT transmission heating up causing it to into limp mode. When I got ready to install, I found there was no place to connect the hoses to the transmission. The vehicle only had the direct "bee hive" cooler. Install was delayed while waiting to get a "4 tube bee hive" from a different supplier for an additional $114.



by:

We installed a tow package on our Ford Flex. The transmission cooler was challenging, but everything else went smoothly. The product works perfectly.



by:

Installed on a 2002 chevy tracker with ease. very well made and all parts provided were well thought out for the installation.



by:

Nice inexpensive transmission cooler. Simple installation, although I didn't use the through radiator plastic ties supplied. Drops transmission temperatures well.



by:

Ive got a 1999 4runner that had the unfortunate luck of having the integrated transmission cooler line rupture inside my radiator. needless to say, the transmission didnt agree very well with having engine coolant running through it and finally died out on me. I bought this transmission cooler to isolate the transmission and the engine cooling systems. The cooler arrived a day ahead of schedule, which is always a bonus. I didnt rate it at 5 stars because I havent had a chance to install it yet and see how it performs, but judging by the reviews that I have read so far, the customer service provided and the prompt delivery, I would say that this transmission cooler will keep my truck running for a good long while. Everything pictured arrived in the box and I have no doubt that it will perform as expected. I will definitely recommend this product and this company to my friends!



by:

The part itself was easy to install and it does what it is designed to do. Only trouble with installation was with the vehicle, I had to remove part of the front cover on my 09' Avalanche to get to it. Also, I wish I had bought a black one to blend in with the rest of the radiator.



by:

for my 06 colorado with the 2.8l i4. also used the derale trans oil thermostat to help with warmup of trans fluid in winter. trans never gets above 190F now and the engine will overheat (212F) before the trans does. perfect upgrade for a light duty truck/van/car to provide a little bit of cooling at a compact size. very satisfied with the product



by:

Very easy install, absolutely no leaks anywhere in the system after putting it into service. I did have to get additional hose for the install due to the location I chose for the cooler (personal preference). I centered it on the bumper side of the radiator to provide the best air flow. Remember to get a quart of transmission fluid to accomodate the larger system volume after the install. I took my grill off to provide the most room for putting the cooler in rather than trying to wedge it between the radiator and grill, made install the nylon fasteners through the radiator and cooler much easier. Should last for many years.



by:

Can't say anything bad about the unit. It was installed in a Jeep Grand Cherokee that I use to haul trailers occasionally that weigh up to 6000 lbs. So far, I've never overheated the transmission at all, which I attribute to the addition of this cooler. Once again, thanks for a great product.



by:

This product is great and installation was not bad at all. Only issue I had was that the GM radiator adaptor should come with this unit when you purchase it for a GM truck. Not as an add-on. Thought I could get it at GM but no go. I Had to work with hoses over 30 min to get them over the fittings even with trans. fluid on the hose and male fitting. So far it looks like trans temp has dropped 30 dg.



by:

The transmission cooler, along with all the other products I ordered from etrailer was an excellent buy. they arrived on time and in excellent condition. The best benefit of ordering from etrailer is the superior customer service. I was even able to talk directly with one of their installers when I had a question.



by:

The trans cooler was easy to install. I had to go and buy some more hose and mounting screws to make it work but I knew that before I started. The hose was because of where I wanted it mounted. The trans cooler is keeping the transmission about 30 to 40 deg cooler then before.



by:

After one of use on a 2005 Honda Pilot, everything is holding up just fine. The one star less is because of the difficulty in installing it on this particular vehicle. Although this is a universal component, it is MUCH easier to install on pickup trucks. Best of luck with a brand new rubber hose going on with any sort of ease.

Our installers typically use some transmission fluid to make installing the rubber hose on the Insta-dapt fitting easier.

Wanted to give my Honda better ability to handle a tow. this baby does the job. Transmission definitely cooler operation since the install. The install was simple and straight forward.

so far so great. Tho sometimes I have to remind the transmission service guys to add a bit more fluid then they are use to.



by:

I purchased this for my C6 Corvette A6 transmission. I did, however, bypass the radiator and only use the transmission cooler for the C6. I purchased and used the Derale Radiator Adapter fitting 259-13035 for both the top and bottom and just capped them off to keep debris out of the reservoir. I also had to make some custom mounting brackets. This is an excellent product and it keeps the tranny in a great temperature range.

Fast order fulfillment.

  • 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...

  • 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...

  • 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...

  • 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. My recommendation is the Derale Dyno-Cool...

    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.

  • How to Determine How Much Fluid Should be Added After Installing Transmission Cooler
    What you will want to do is check the transmission fluid level after installing the Derale part # D12906 and then add as much as needed. Most likely around a 1/2 qt would be needed but that will depend too on if you spill any fluid (most do) and how long of lines you use.

  • Tips for Keeping a 2008 Chevrolet Colorado Cool While Towing a Trailer Into the Rockies
    It sounds like you have really done as much as you can to ensure that your 2008 Chevrolet Colorado has the advantage while towing. I think you stated the reason without realizing it, you are going up steep inclines while towing a trailer. Even without a trailer your vehicle will experience extra heat due to the strain of driving uphill. Add to that the weight of a trailer and whatever cargo that if put into the Colorado itself and that is why you cannot go 60-65 mph safely. The most efficient...

  • 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.

  • 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.

  • Can a Transmission Cooler Bypass the Factory Cooler on a 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.

    As long as the transmission of your 2006 Toyota RAV4 has external lines you can install a transmission cooler. If you find the radiator there should be two metal lines that run to it that would be used for the factory cooler. You can also check out the transmission, if you find lines running from it those can be used for installing a cooler. The part # D12906 is a very popular option that would work well as long as you have room for it. I actually have it on my car and it does a great...

  • What to do if a Transmission Cooler Line Comes off and Fluid is Leaked
    It really is hard to say, your best bet would be to repair the line if you have not already. Fill the transmission up with the appropriate amount of fluid and then take it to a transmission repair shop to have them check it out. Hopefully you get lucky, but there could be a wide range of potential internal problems depending on how long the vehicle was attempted to be driven and the temperature of the transmission.

  • 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...

    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.

    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...

Any extra gear on that trailer could place you over the towing capacity of your Compass which could possibly cause damage to the hitch or the vehicle.
