2015 Subaru Outback Wagon - Derale Dyno-Cool Tube-Fin Transmission Cooler Kit - Class II - Economy
- Tube-Fin Cooler
- With 11/32 Inch Hose Barb Inlets
- Standard Mount
- 13W x 7-1/2T x 3/4D Inch
- 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 Subaru Outback Wagon'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.

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.

2005 Honda Pilot
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.

2009 Audi A6
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.

Jeep Grand Cherokee
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.

1999 Toyota 4Runner
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: Dave C12/10/2012
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: Barry08/14/2016
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.

2012 Nissan Rogue
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.

2006 Chevrolet Colorado
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: Rick09/19/2019
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.

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

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

2008 Chevrolet Silverado
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.

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.

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.

- Which Derale Radiator Adapter Fitting Kit for a 2000 Ford Taurus WagonI spoke with my contact at Derale and the reason there are two different hose fitting recommendations is because there are two possible diameter hoses that are on the 2000 Ford Taurus Wagons. To determine the correct fitting you will need to know the threaded diameter of the transmission fluid line fitting in your vehicles radiator. If you need a 3/8 inch fitting you would need a Derale Radiator Adapter Fitting Kit, part # D13014. If you need a 1/2 inch fitting I would recommend a Derale...
view full answer... - 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.
view full answer... - Does a Transmission Cooler Need A Thermal Bypass for Sub-Freezing WeatherI 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...

You won't need any additional part for this installation.
view full answer... - Transmission Cooler for 2007 Jeep Grand CherokeeThe 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...
view full answer... - What Transmission Cooler Kit is Best for a 2001 Saturn L300The D15505 is a bit larger than what a 2001 Saturn L300 would need or could fit. There are 5 recommended kits for your L300 based on the vehicle size and towing capacity. I have added a link to them below. Transmission kits are not vehicle specific. However, you need to make sure you have space to accommodate the cooler. On each of the cooler pages, you can find the dimensions of the cooler. Measure the space on your vehicle where you would like to mount the cooler and make sure you have...
view full answer... - Transmission Cooler Recommendation for a 2005 Acura MDX Towing a 3,750 Pound Boat and TrailerThe 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...
view full answer... - Transmission Cooler and Thermostat for a 2011 Subaru ForesterTransmission 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...
view full answer... - Suitability of 2008 Jeep Compass for Towing Trailer Weighing 1800 LbsIf the weights you have given me are correct, you should be able to tow the trailer. Keep in mind that you are less than 200 lbs away from your towing capacity. 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. Since you are so close to the towing capacity of the vehicle, a transmission cooler would be a wise investment. I would recommend the Derale Dyno-Cool Tube-Fin Transmission Cooler,...
view full answer... - Transmission Cooler Recommendation for a 2008 Honda PilotThe 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...

If it's the engine you're wanting to cool, you can grab this kit # D15605 which comes with a sandwich adapter with multiple thread sizes to ensure that it will thread into your Tacoma. If you're wanting to add an oil cooler to your 2010 Toyota Tacoma, you won't need the Derale Thermostatic Sandwich Adapter # D25720. All you need is a cooler like this one # D12906. The cooler will just go in between where the transmission...
view full answer... - Transmission Cooler Recommendation for a 1996 Nissan Pathfinder Towing a 1900 lb TrailerThere really is not a down side to using a transmission cooler on a vehicle. It has been proven that transmission coolers will prolong the life of a transmission. Especially when the vehicle is towing a trailer. I would strongly recommend you install one since you will be pulling a 1,900 lb trailer with your 1995 Nissan Pathfinder. The power switch might enhance the shift points so that it will perform better while towing, but it will not prevent excess heat from building up in your transmission...
view full answer... - Where is the Best Location to Mount the Derale Dyno-Cool Tube-Fin Transmission Cooler KitThe Derale Dyno-Cool Tube-Fin Transmission Cooler Kit, part # D12906, should be mounted after the radiator. So it would be in line from the fluid return line, this is the recommended way to install part # D12906. For mounting the unit, it is recommended that part # D12906 be mounted behind the grill and in front of the Air Conditioning Condenser Core, (see video link for reference). You can mount part # D12906, between the condenser core and the radiator but it will cut down on the cooling...
view full answer... - What to do if a Transmission Cooler Line Comes off and Fluid is LeakedIt 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 the Derale Transmission Cooler Kit Come with What is Needed to Install on a 1997 Chevy LuminaThe Derale Dyno-Cool Tube-Fin Transmission Cooler Kit, # D12906, comes with everything you will need to mount and install it on your 1997 Chevy Lumina. The system installs in line with your current transmission hoses. I have included an FAQ article on Transmission Coolers below. There is a lot of helpful information, including the best places to mount the unit. I have also included a video showing installation of a transmission cooler. Installation will be similar on your vehicle.

There will be 16 plastic rivets that will need to be removed. You can use a screwdriver to pop them out. Take your time getting these out so you do not break them. Once the grill and bumper are removed you will have plenty of room to work to install a transmission cooler like the # D12906. I am going...

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...

view full answer... - Recommended Transmission Cooler For 2005 Toyota 4RunnerWe do offer quite a few transmission cooler kits for your 2005 Toyota 4Runner, but we do not offer replacement hard line or connectors to attach to your transmission. You will need to get those parts from a local auto parts store. For a transmission cooler I recommend the Derale Dyno-Cool Tube-Fin Transmission Cooler Kit # D12906 which is ideal for mid-sized trucks and SUVs like your 4Runner. This kit includes hose, mounting hardware, and hose clamps, but since we have not had a chance...

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...
view full answer... - Is the Hose Included with Derale Transmission Coolers Long Enough for Install on a 2004 Honda PilotThe hose that is included with the Derale transmission cooler, # D12906, is long enough for typical installation locations, including in front of the radiator, as long as it is on the same side as the factory transmission cooler lines. It is entirely possible on any vehicle, including a 2004 Honda Pilot, that you may need to acquire additional hose. I have yet to have a customer complain about the hose not being long enough. I have included some helpful links on transmission coolers for you.

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...

I recommend going with the Curt Adjustable Width Trailer Receiver # 13703 , because it has a slightly higher 350-lb tongue weight capacity.
