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 coolers, 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. Add to that a powerful tornado fan that ensures optimum airflow at all times, no matter the environment, and you have a super-efficient heat exchange unit.

2007 Toyota FJ Cruiser

Awesome remote transmission oil cooler. Attached at the rear under belly of a Toyota FJ Cruiser, 2007.

2007 Ford F-150

Awesome product! Received it yesterday. Custom fabricated brackets for it to mount below my auxiliary trans cooler on my 07 fx4 f150. Installed the on off switch on out side of transmission and the fan works great!

2010 Toyota Highlander

excellent quality product, I have intalled the fan/cooler on a toyota highlander 2010 without tow package not infront of the a/c radiator but exactly at the same place as toyota install the oem transmission cooler just behind the right fog light. I have a travel trailer of 3300 lbs dry, (4000lbs gross weight) and before my transmission temperature was around 215-220 F with a standard transmission cooler(without a fan) infront of the a/c radiator, but now with my new derale fan cooler, its around 180F after a long climb. I am totally satisfied. I had to build a bracket to fit the cooler in this tiny space behind the fog light, it took me 6-7 hours .

2015 Toyota Tacoma

Nice product


Mounted between fuel tank and transfer case. Larger 6.0 cooler would go in front of intercooler. Dont need anymore heat there. This was cheaper and works great in this position. Wrapped exhaust near the lines as they have to dump out on right side of trans. and I did not want any hard 90 degree turns with all this extra plumbing. Keeps temps way lower. Also installed oversize/cooler pan.
FYI using temp sensors in pan and in valve body. Pan is regularly 30 degrees cooler than valve body.


Have not installed it yet, but looks impressive! This this is like a beast cooler. Will be installing it this week before a long distance rv trip.


Easy install, and works as specified. Would put on future high performance vehicles


Great product and prices really awesome service


Review from a similar Hyper-Cool in Transmission Coolers

I was very impressed on quality and ruggedness. Its heavy and works great. This is a must in South Texas especially pulling a trail.


Review from a similar Hyper-Cool in Transmission Coolers

Love my engine oil cooler. I was having overheating problems with my Dodge truck while towing on a hot day. I asked the guys at etrailer if I should add a bigger radiator, and engine oil cooler or another tranny cooler. They nailed it when they recommended a supplemental engine oil cooler. I now can town my fifth wheel RV trailer on the hottest days and in the mountains without overheating. I do still have to watch the temps and if they start to get over 260 f or so I downshift a gear or two to get greater fluid flows. The only reason I am not giving this 5 stars is that with the supplied hose clamps I was plagued with constant slow leaks. I finally bought a much higher end hose Clamp which did solve the problem.


Review from a similar Hyper-Cool in Transmission Coolers

I was surprised at the lack of feedback on these products, and the differences in opinions. I tow a fare amount, between 7000lbs and 9500lbs. My vehicle is a 2013 Dodge Ram 1500 with the 8 speed transmission. ( outside temperature 20-30 deg Celsius ). Before I installed this engine cooler my temperature ran around 115 deg Celsius on a flat pull and 130 - 135 deg Celsius on most hills. After a hill it took a long time to drop in temperature, most time it hardly dropped. Now I rarely see 115 deg Celsius on a hill, and recovers to 100 deg Celsius very quickly. So in short I'm very happy with this product. I would recommend it to anyone that Tows.


Review from a similar Hyper-Cool in Transmission Coolers

Excellent product, quality parts and fittings for multiple installation platforms. Took about 4 hours to install but was a custom install under bed of truck.


Review from a similar Hyper-Cool in Transmission Coolers

Appears to be well-built and wasn't too hard to plumb in series with the existing oil cooler. Unfortunately with my 2010 Suburban it did not make any difference in the oil sump temperature shown by the computer - either daily driving or while towing. I plan on borrowing a laser thermometer to see what the actual input/output temps are.


Review from a similar Hyper-Cool in Transmission Coolers

Great product. Keeps transmission oil cool. Happy with my purchase

Cooler is working great. Transmission oil is keeping cool. I havent touch it since I installed it.

  • Mounting The Derale Hyper-Cool Remote Transmission Cooler Kit w/ Fan In 2013 GMC Sierra
    For your 2013 Sierra 1500, I recommend mounting the Derale Hyper-Cool Remote Transmission Cooler Kit w/ Fan, -6 AN Inlets - Class V, # D13960, using your second option. I'd leave the stock cooler alone and mount the Derale cooler with fan in front of the passenger wheel well. The stock cooler location will allow that cooler to function at its potential and then you can add the Derale cooler, which can function almost anywhere with its attached fan to further cool your transmission.

  • Transmission Cooler Recommendation for a Street Rod with Limited Air Flow and Space
    Since you plan to install a transmission cooler in an area that won't get direct air flow you will want one with a fan. Since you said space is a premium you would want a smaller one. The Derale part # D13960 would be a great option as long as you have the room for it. It measures 13" wide x 10" tall x 5-5/8" deep. This stacked plate cooler is incredibly efficient and would work well as it has a fan that can flow 500 cfm.

  • Recommended Transmission Cooler with a Fan for 2007 Nissan Frontier
    Our most popular transmission cooler with a fan is the Derale Hyper-Cool # D13960. This is a stacked-plate cooler which is the most efficient style available. It also uses a 500-CFM fan for airflow. You can mount it anywhere you have room in your engine compartment since there's no need for airflow. It's most common not to replace your factory cooler but to add an additional supplement cooler.

  • Mounting Of Derale Hyper-Cool Remote Transmission Cooler Kit On 2002 Chevrolet Silverado 2500 HD
    I contacted our representative at Derale and he informed me that the Derale Hyper-Cool Remote Transmission Cooler Kit With Fan, part # D13960, can be amounted anywhere. Since it uses a fan for cooling, it is not necessary to use the radiator for cooling as the fan is strong enough to provide cooling power. It may be beneficial for more cooling efficiency if you can mount it in front of the radiator, behind the bumper, but it is not required. Transmission fluid cannot be cooled too much...

  • Will Derale Remote Mount Transmission Cooler # D13960 Fit 2012 Chevy Suburban
    While we don't have specific fit info for the Derale Hyper-Cool Remote Transmission Cooler # D13960 that you referenced the dimensions of this cooler would pretty easily fit the available space you have. This cooler measures 13" Wide x 10" tall x 5-5/8" deep but what's really great is that even if for some reason it didn't fit there since this has a fan on it you could really install it about anywhere and the fan would pull enough air to make it efficient still.

  • Best Transmission Cooler Recommendation for 2012 Chevy Suburban
    One really efficient and larger transmission cooler would be all that you'd need. In theory, the more the better but in reality one really good one would be all that you'd need. The Derale Hyper Cool part # D13960 is a stacked plate style of cooler with a built in fan which would be more than adequate. The stacked plate coolers are by far the most efficient and the fan ensures that you'd always have enough airflow to cool the fluid. It also allows you to mount basically anywhere as it...

  • Is Derale Transmission Cooler a Good Option for 2020 Toyota 4Runner
    The Derale Hyper-Cool Remote Transmission Cooler Kit # D13960 would be an outstanding choice to add to your 2020 Toyota 4Runner with a 4.0L V6 engine. The reason is because it's a stacked-plate cooler, which means it gives you the most surface area with which to cool fluids. As for mounting, there isn't a recommended or suggested spot on specific vehicles for these types of coolers. They are designed in order to fit in any location where there is space, and an experienced installer will...

  • Transmission Cooler For 2014 Nissan Titan
    Cooler failure is VERY expensive! That's why I recommend getting a Class V cooler like # D13960. This one comes with a fan too which is nice especially when your not moving much in the heat hauling something. The fan will make sure that the cooler is getting plenty of air flow even if your not moving or hardly at all.

  • Can the Factory Transmission Cooler on a 2005 Chevy Silverado 2500HD be Replaced with Remote Cooler
    It would be best to use a transmission cooler as a supplemental cooler to the factory transmission cooler.

I have included a link to the installation instructions for you.

  • Remote Mount Transmission Cooler Recommendation for a 2008 Dodge Ram Cummins
    For as big of a truck as you have I would go with the Derale Hyper-Cool Remote Mount Transmission Cooler part # D13960. This is Class V stacked plate cooler (the most efficient style of cooler) with a fan that can flow 500 cfm of airflow that would do very well. This kit also includes all of the necessary rubber lines and hoses to install on your vehicle. I attached a couple FAQ articles on transmission coolers for you to check out as well.

The cooler on this setup is a stacked plate design which is the most efficient style on the market and the fan will flow 500 cfm of air through the cooler to keep the temperatures down. If your transmission temp gauge is maxing out then I would strongly urge you to install this product so that...

  • Recommended Fan-Powered Transmission Cooler for 2009 Toyota Sienna
    For a fan-powered remote transmission cooler for your 2009 Toyota Sienna I recommend the Derale Class V Hyper-Cool # D13960. This high-efficiency stacked-plate cooler kit includes the cooler, fittings, hose and all hardware required for installation. The fan's 500-CFM (cubic-feet-per-minute) airflow cools your transmission fluid no matter your driving speed, unlike passive coolers like the Derale # D13503 that rely on air flow from your driving speed to cool your transmission.

Flexibility in mounting point is one of the advantages of a fan-powered cooler. Since they don't rely on passive air flow for cooling they'll work effectively almost anywhere you can fit one.

  • Can You Run Larger Cooler Lines Into Smaller Openings?
    Generally speaking, you won't want to run a larger line into a smaller opening with an adapter because the difference will create a buildup of pressure that will likely cause the line to burst, but running a smaller inlet into a larger port is possible. I checked with Derale and they mentioned that running a smaller line into a larger port just means that not as much fluid is going to be pushed into the cooler and it will run less efficiently, but it won't damage the cooler. Derale does...

  • Comparing a Remote Mount and Standard Transmission Cooler
    The Derale Hyper-Cool Remote Transmission Cooler Kit w/ Fan part # D13960 would absolutely provide greater cooler power than the Derale 25-Row High-Performance Stacked-Plate Cooler part # D52508. The reason for this is because the fan provides constant airflow which in turn translates to more cooling whereas with the standard cooler you would be subjected to the mobility of the vehicle for cooling power.

    The difference between the kits is the size AN fittings that come with either. Aside from that it's the same coolers and the same fans. The Derale Hyper-Cool Remote Transmission Cooler # D13960 comes with -6 AN inlet fittings and the part # D15960 comes with -8 AN fittings. -6 means the hose is 3/8 inch diameter and -8 means 1/2 inch diameter. The bigger the diameter the more fluid can flow through it. Either are a great option for your truck.
