Derale Transmission Coolers - D13504

11" Wide x 12" tall x 7/8" deep, efficient heat exchanger will prolong the life of your transmission and improve its overall performance. Specifically designed for vehicles with late-model, electronic overdrive transmissions.


Features:

  • Prolongs life of transmission
  • Improves overall performance
  • Prevents heat-related failures
  • Has furnace-brazed aluminum construction and 3/4" wide turbulator plates for more efficient cooling
  • Includes complete mounting kit, OEM spec hose with stainless steel clamps and Insta-dapt radiator adapter
  • Recommended for full-size trucks and SUVs


Specs:

  • Inlets: 11/32" hose barb
  • Overall dimensions: 11" wide x 12" tall x 7/8" deep
  • Distance between inlets: 10-1/4"
  • Mounting dimensions: 10-1/2" tall by either 5-1/4" or 6-3/4" wide

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.


One of the more popular cooling systems available, the radiator-style, plate-and-fin heat exchanger provides increased surface area so that fluids can spread out along the finned chambers to cool faster. In addition to the increased surface area, this cooler also features turbulator technology, whereby fluids are agitated continuously, not only to facilitate heat transfer, but also to prevent any undesirable drop in pressure.

Video Transcript for Derale Series 8000 Transmission Cooler Review

Speaker 1: Today we'll be having a look at the Derale 8000 Series line of plate-fin transmission coolers. Here's what our transmission cooler looks like installed. Now, the reason you're gonna want an auxiliary transmission cooler such as this one on your vehicle is quite simple. Heat is the enemy of transmissions. It is the number one cause of premature failure on your transmission. By reducing the temperature of the fluid inside your transmission, you will extend the life of it, and also have added cooling abilities.

The colder the transmission fluid is, the more heat it can actually absorb. Plus, we are expanding the cooling capacity of the system by having additional room for more fluid, which, will also help reduce the temperature.Now, you may ask, "How is this important to me because my vehicle already has a transmission cooler build inside the radiator" Well, it's quite simple. If you we're ever planning on doing aggressive driving, or towing a trailer, towing a trailer causes additional wear and tear on your transmission, and causes increased fluid temperature. By cooling the temperature down further, you are making it easier on your vehicle in order to tow that extra weight. Now, how this works being installing in addition to the factory cooler inside the radiator, the fluid will leave the factory transmission cooler from the radiator, go inside of our auxiliary cooler here that we installed, get cooled down even further, and then go back into the return line that goes into your transmission.

So, you're adding additional cooling capacity, and a secondary cooler by having this aftermarket cooler installed.Now, for a few measurements to better assist you in choosing if this cooler's gonna work for your vehicle. At its widest point, it's 11" wide. From the very top to the very bottom, it's 7 1/4" tall, and it is 7/8 of an inch thick. Now, one thing our customers have noticed, when they're installing this cooler on a vehicle, they have noticed when they're installing it inline with the factory transmission cooler, that they have needed additional hose. Now, we do have additional hose available on our website.

Now, the 8000 Series of Derale transmission coolers are plate-fin design, and the plate-fin design increase surface area. The more surface area that we have, the more cooling capacity that we have. The more of your fluid you can spread out over a larger distance, the more it can get cooled down to reduce the temperature of your transmission.This cooler also features turbulator technology to help agitate the fluid passing through it. To help with heat transfer, but also to help prevent any drop in fluid pressure. Our transmission operates off fluid pressure, so if it falls below a certain amount, it may not shift gears properly.

By maintaining our fluid pressure, our transmission will shift gears properly, and work as it's designed. This cooler has an aluminum construction, so we don't need to worry about it corroding or rusting out over the course of time. It also has a nice gloss black finish, so it'll be easily concealed behind the grill of your vehicle, and it won't be visible are you're looking at the front of your car.And that completes our look at the Derale 8000 Series line of plate-fin transmission coolers.

I didn't know how to select the right trans cooler for my towing needs and I probably would have figured out how to mount it but with the help I got from your web site, I knew I had the right cooler and I knew how to install it in my vehicle. I saw a video of a cooler just like mine installed in a truck exactly like mine. How cool is that? etrailer.com is now my only source for trailer and towing parts. 408106

Hello Gang, I have a 2013 Chevy suburban and tow a 7K plus travel trailer. While we were towing to Colorado near Cripple Creek the temps were low 90's and my trans spiked at 230. Had to pull over to let it cool down. Now keep in mind my suburban does not have a HD trans cooler just the stock radiator cooler. Fast forward one year now my stock trans line is starting to leak from the rubber hose so it's time to change. Decided to order the larger trans cooler might not have been the best idea as it's larger then where I wanted to put it. So after taking off the front bumper, headlights misc brackets and lots of bolts I was able to get it up behind the "A" frame bracket in front of the radiator. Make sure if you go this route to put the rubber hoses and clamps on before installing because you will not be able to install the hose after. The bracket the holds the hood latch has openings that just happen to line up with the inside bolt holes on the cooler. Hoses facing down You will need to cut the bottom of the plastic out of the way to route the hoses under the frame. Cutting the original trans cooler line was easy and the rubber hose was long enough to make both connections so I did not need the adapter. If I used the adapter the rubber hose would be too short. On the bottom I used the foam pads between the cooler and the frame and secured it with heavy duty Zip ties. Can't wait to test it out this summer. I forgot to take pictures of the final install but did take one picture showing the "A" frame in the middle of the radiator. It fit's perfectly behind it. 613917

Great value for the price and free shipping, package arrived on schedule, was packed extremely well, (I would know, retired Postal mail carrier), Derale 13504 transmission cooler was exactly what was described should work well for me to tow a 3500lb travel trailer with my 2008 GMC Acadia. Will be installing the cooler this week. This definitely should keep my transmission from over heating, it's rated somewhete at 22500 GVW. My vehicle and travel trailer CGVW is approximately 9000 lbs. 462784


Comments

The Derale 13504 has kept my transmission from over heating, have towed my travel trailer over 3600 miles no problems with transmission over heating in my 2008 Acadia SLT. Will be installing a auxiliary fan in front of my radiator to assist when in towing this summer. .

Item arrived promptly and well packaged. Installed the cooler on my 2001 silvarado z71 5.3L on a warm Redding California afternoon 105f. It only took about 1/2 hour to install it inline with my stock cooler. Promptly the next day I pulled around my utility trailer loaded down with a 8x12 wood shed, outside temp on my mirror was reading 117f. Two hours of pulling and pushing and the shed was in place. It was hot I was hot truck was not even with the AC on full. The next punishment will be pulling the 25' camper kids dog and all essential beverages over the mountains in the heat to the coast. 201919

Hey Mike could you specify where and how you mounted the second cooler please? Having trouble figuring that out!

TannerI mounted the cooler on the passenger side of the radiator using the stock transmission cooler mount and the headlight mount. The cooler was mounted sideways and all the way to the top of the compartment i dry fit it and made sure the plastic radiator cover would still snap into place as well as the hood closed with no issue before installing it inline with my stock cooler. Tight fit but it works and works well.

Installed this on my 04 denali xl. Took me about an hour. I bolted mine on instead of using the zip ties. It is the right size to fit between the grill and the condenser. Right next to the tiny factory installed cooler that doesnt get any air because of the huge gmc logo. I installed mine in line with the factory cooler. It keeps the tranny dramatically cooler when towing. It is an inexpensive tranny saver. Etrailer has a great how to video that works for almost all the 02 to 07 yukon and suburbans. Dont forget the fitting adapter that fits into the cooler. 565715

This cooler was delivered promptly and as advertized and will fit in front of the radiator and behind the grill. The 4 foot length of cooler hose is not long enough to install this cooler on a 2006 Dodge 5.9 diesel. I am a bit disappointed that I will need an additional 4 feet of cooler hose to complete this installation. I may also have to purchase a fitting but I'll find out later. I don't have pictures yet as the cooler has not been installed. I don't mind sending pictures later. Thanks, 14753

I received the cooler on time and in fine condition. The factory box was well packed and all items were enclosed. I mounted the cooler using flat aluminum bar stock so I could leave a one inch space between the cooler and the front of the A/C condenser as I feel this will give me maximum transmission oil cooling. I used this product to replace a tube and fin cooler which was not doing the job even when not towing my trailers. I have not towed with this cooler yet but due to its construction I feel it will greatly reduce my transmission oil temperatures. Walt 9-22-2018 567912

I have a 2010 Silverado 4x4 with a 6speed auto trans. I load it with a 3000 bl. cab over camper and take on the Sierra Nevadas a lot. Trans temp is very important to me as a former GM certified automatic transmission technician. For two week prion to installing this cooler I documented my trans temp reading under different driving conditions and ambient temperatures. Trans ran consistently between 180 to 210 degrees with no load in the bed. After installing this cooler and driving it under the same conditions as before, I have a clear in temp by 40 degrees. I also notice that if temp goes up from climbing a large grade, it s back down MUCH faster. A lot of these reviews talk about how easy it was to install the cooler... I would like to stress how well it works!!

2009 GMC Yukon XL towing a 7,800lb travel trailer from California to South Carolina..... I don't believe the Yukon would have made this journey if it wasn't for the additional transmission cooler and engine oil cooler. Dragging the travel trailer through the mountains during the heat of the summer was taxing. However, my transmission never got above 190 F when it was over 100 F outside. Before installing the oil cooler AND transmission cooler, my engine temp would go to the 1-2 o'clock position and transmission temp would get up to 210 F. Highly recommend this product. 548155

After installation which took about 3 hours. I have logged 5000 miles of some of the highest mountain passes in North America. Not a single issue with the cooler as it operates between 160- 205 degrees . Great product. Installed on 2011 Yukon XL 5.2 engine.Temps before installation were 30-45-degrees higher. 383217

I recently had the chance to use the Derale 8000 series transmission cooler during my last camping trip and was very impressed. I have a 2001 7.3 Powerstroke with 4" exhaust, S&B intake, gauges and a DP Tuner (60hp tow). I pull a 10,000 pound 5th wheel around Colorado. It seems like every where I pull in Colorado is up hill. It was common to see my transmission temp easily and quickly reaching 210-220 when towing mountain passes. Just before my last trip I installed the Derale cooler and the highest trans temp I saw was 190 at the top of Wilkerson Pass. What is more impressive was how quickly the temp dropped as I came out of the pass. For most of my trip my trans temp stayed around 180. While pulling in the city I saw temps around 200 which I assume was due to stop and go driving and not having the constant airflow through the cooler. I installed the cooler right behind the stock front grill to the vertical post with self tapping screws (the grill still fits perfectly). I then used two thin strips of metal that I got from the hardware store and secured them to the cooler and to the second vertical post. I wanted the cooler in the front of my truck to get maximum airflow. I then spray painted the metal strips black just for looks. I did have to buy an additional 4' of hose due to the location where I mounted the cooler. The optional instal kit was simple. The adaptors screwed in my radiator with no problem at all. Once I decided to mount the cooler the entire project was quick and simple. 143154

Solidly built, installation was relatively easy. Installed on a 2008 Trailblazer. Contrary to what I've read, the supplied hose was long enough. I had to cut off nearly 6" of excess. Mount in a location / orientation where the inlet / outlet are centered on and closest to the trans lines and it shouldn't be an issue. 92591

I installed this on my Toyota 1996 T-100 3.4: I picked up a piece of universal hangar strap, 2-8mmX1.25 bolts & lockwashers at building supply; 3 gal tranny fluid (flushing system including torque converter), 4' extra hose & extra clamps @ auto supply. I first mounted flange to central member with a couple screws; then bent 17-1/2" of the strap to pass the AC line ( the holes for the two bolts actually lined up to the two factory threaded holes available!!PTL). From there it's almost a done deal; hookup the cooler to the return side out of the radiator and let a half gallon at a time pump out till you get new fluid: then make up your return hose to the steel return line. It's oversize but this is FLA and it pulls. Heat is death to transmission fluid; and then the transmission! Good project. 297264

Used on 2012 Cadillac Escalade 6.2L. Lowered trans temp from 202 to 180 F during summer runs with our travel trailer. I’m ordering a second one for my 07 Silverado 5.3L. I have a pet peeve with having trans temperature over 200 degrees. Highly recommended. Install on Escalade was difficult because well the whole front needs has to be removed, but the install on my Silverado shouldn’t take more than 20 minutes. Excellent product. 502246

I installed the cooler last weekend in my 2008 Silverado. I've included some pictures. I made a strap to support the upper portion of the cooler and thru bolted the lower to the existing bracket. The hood bracket lower bolts had to be cut down to 1/4" length so they would not contact the cooler. The lower mount bolts had to be spaced to give the hood mount weld nuts clearance. Now to see how it does with a trailer and the Pacific Northwest hills. 81391

I installed this trans cooler on my 2009 Yukon. The installation video really made it much easier. I just pulled my boat under the same conditions I had prior to the install and I am very pleased with the results. Prior to mod, my trans temp got up to 204 degrees. With cooler, it was 160-165. 560929

The installation was not too bad. Make sure you order the correct adapter. The adapter it comes with is universal so I had to order a GM adapter after I started the installation. It mounted really clean on my 2014 Silverado. Worth the money for late model GM’S to keep the transmission heat down. 664948

I was looking for a tranny cooler for my 09 Tahoe but was unsure of how easy it would be to install. I ran across etrailer's step-by-step video on how to do the installation and all off the parts needed. Couldn't be easier. Everything was as advertised and went smoothly. Dropped transmission temps significantly when pulling my travel trailer. I am extremely happy with the whole experience start to finish. 620430

I purchased a transmission cooler to install on my truck for towing. Although I have not towed yet, it has already dropped my trans temp 30 degrees. All parts were provided and it all came undamaged. I did have to buy more hose as the hose provided was not long enough for installation but other than that everything was excellent. Thanks etrailer.com!!! 619468

We've had it for a year in our 2008 TrailBlazer 2WD with 4.2L inline 6 cylinder. I think it's about the largest that would fit and we got it for a towing our 21' expandable camping trailer that can be about 4,500 lbs. max. Works great, although I added another install kit to be sure I had enough hose and the extra brackets and connection adapters. I did not want to use the mounting parts that poke through the radiator and A/C condenser fins, so I got the Derale kit with brackets and hose in an affordable kit together, part # D13006. 520230

Installed the cooler on a 95 ram 2500 cummins, and it is great! I pulled a dump trailer with 2 tons of dirt through WVA during a 95° day while keeping trans temperature under 170°. Pretty impressed with this compact cooler 423882

While pulling a hay trailer of hay in a field with my 2000 F250 my transmission got hot and blew a seal which leaked transmission fluid out on to my hot exhaust which then caught the ground and the truck undercarriage on fire.. After that episode I replaced the seal and fluid in the truck and purchased this aux cooler. Installed quick and with ease.. So far I havent had any more issues with over heating in the transmission....Great product have recommended this to others that pull or haul with their truck.. 414360

About a year ago I bought a trans cooler from etrailer for my 2008 Silverado because I was having cooling problems. Once I installed my new cooler all my problem disappeared. Thanks etrailer Mark 374218

  • How to Mount a 7-Way Connector on a 2017 Nissan Pathfinder with the Curt Hitch # C13309
  • If you were to install the Curt Trailer Hitch Receiver # C13309 on your 2017 Nissan Pathfinder then you would need to mount the Curt T-Connector # C56357 directly to your rear bumper fascia using the mounting bracket # PK12711U. To avoid this you can use the Curt Easy Mount Bracket # C58000 instead. Since the Draw-Tite Trailer Hitch # 76031 does sit below the rear bumper fascia you would be able to use the no-drill mounting bracket # C57202 along with the part # PK12711U. The Curt...

  • Transmission Cooler for 2005 Chevy Silverado 2500HD
  • It's definitely not abnormal for your transmission fluid to heat up while towing, especially when you're going up hills that force the truck to work a lot harder. To help with this adding a transmission cooler like you mentioned is a great idea. For your 2005 Chevy Silverado 2500HD I highly recommend the Derale Hyper-Cool Remote Transmission Cooler Kit w/ Fan # D13960. This cooler will do a great job of improving the performance and function of your transmission with its reversible...

  • Recommended Transmission Cooler For 2010 Chevrolet Silverado 1500 5.3L V8 323 Cubic Inch Engine
  • For your 2010 Chevrolet Silverado 1500, I think you are on the right track with the Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13503 you asked this question from. It is 11" wide x 8-3/4" tall x 7/8" deep. For your specific application, I recommend a plate-fin cooler like the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class IV - Efficient, # D13504. This plate-fin style provides increased surface area for the plates to cool faster. This transmission...

  • Installation of Derale Transmission Cooler in 2013 Chevy Silverado 1500
  • It is recommended to use the # D13504 in addition to the factory cooler on your Silverado. This will further help cool the transmission fluid. If you determine you will remove and replace, then you will need the adapter fitting # D13035. My recommendation if that is the case is to use the Derale Dyno-Cool Remote Cooler with Fan and Hose Barb Inlets # D12743. This will ensure you have proper cooling to protect your transmission with the integrated fan. Then you simply need to determine...

  • Transmission Cooler Recommendation for a 2016 Chevy Silverado 1500 with 5.3 Liter
  • The general rule is to keep the transmission fluid at or below 200 degrees Fahrenheit. When towing, especially in the mountains and in summer time, the transmission fluid temperature can increase much higher so adding a supplemental cooler is a good idea. A supplemental cooler can decrease the temperature significantly due to more airflow to the fluid and more capacity (fluid) in the system. The most popular cooler for your 2016 Chevy Silverado 1500 is # D13503. But if it were me...

  • Installing the Derale Series 8000 Kit # D13504 on a 2008 GMC Acadia SLT2 V6
  • When installing the Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13504 on your 2008 GMC Acadia SLT2 V6 there really is no "correct" way to orient the cooler as it can be mounted with the ports being up, down, left, or right as you mentioned. I have attached the installation instructions for you to check out, but for the hose connections you will need to do the following: 1. Disconnect the return transmission cooler line from the radiator. 2. Take the supplied Insta-dapt...

  • Transmission Cooler Recommendation for 2007 GMC Yukon Denali
  • The transmission cooler part # D13504 would be exactly what you need. This is a large cooler that would work well for your 2007 GMC Yukon Denali. I attached an install video that shows it being installed in a very similar 2009 Yukon as yours. Your engine temperature doesn't really seem that bad at all. But the transmission cooler will help slightly with that since it will allow the factory transmission cooler to run cooler as well which is connected to the radiator. Also the transmission...

  • Recommended Transmission Cooler for 2012 GMC Yukon
  • The Flex-a-Lite FLX4126 will work for your 2012 GMC Yukon and comes with the necessary parts needed for installation, though there is a better option I recommend you. The Derale # D13504 is a plate-and-fin style cooler, which is a more efficient option than the tube-and-fin style that the Flex-a-lite is. The difference is that the plate-and-fin style cools better because smaller and flatter plates allow more fluid to be cooled. Additionally, the bigger the transmission cooler the better,...

  • How Difficult is it to Install a Transmission Cooler on a 2012 Ford F-150
  • Transmission coolers are fairly simple to install requiring just a bit of mechanical aptitude and some basic tools. If I had to rate the process on a scale from 1 to 10 with 1 being easy and 10 being hard, I would have to say about a 5. I have attached an install video for you. The process to install the cooler will not be the same as the attached video for your truck but very similar as the process will only differ slightly. As long as you have 11" wide x 12" tall x 7/8" deep of space...

  • Recommended Transmission Cooler For A 2013 Ford Expedition XLT
  • You are correct in that towing a trailer over 6,000 lbs. with your 2013 Ford Expedition XLT will require you to have the factory equipped heavy duty tow package, according to the vehicles owners manual. The factory equipped heavy duty towing package came with additional towing supplements such as a 7-way wiring harness, auxiliary transmission cooler, electric brake wiring kit, and a trailer brake controller. No, the Expeditions without the heavy duty factory towing packages did not come...

  • Comparing the Derale 7000 and 8000 Series Coolers for a 2000 F-250 with the 7.3L V8 Diesel Engine
  • The Derale Series 7000 Transmission Cooler Kits like part # D13105 has a tube-fin design whereas the Derale Series 8000 Transmission Cooler Kits like part # D13503 has a plate-fin design. The plate-fin design is superior to the tube-fin design in that it has internal turbulators to help the oil cool faster and prevent pressure loss. For your 2000 Ford F-250 with the 7.3L V8 Diesel Engine, I recommend using the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13504 which...

  • Recommended Transmission Cooler for a 2017 GMC Sierra 1500 with the 6.2L V8 Engine
  • I spoke to my contact at Derale about adding a transmission cooler to your 2017 GMC Sierra 1500 with the 6.2L V8 engine and they informed me that there should be no problem using one so long as you install it after the factory transmission cooler. I cannot confirm what your truck was or was not equipped with but its sounds like you are referring to a bypass function that reroutes the transmission fluid from the cooler until it reaches a certain temperature. Unfortunately, there would...

  • Best Transmission Cooler for a 2003 GMC Sierra 2500HD with 6.0L V8 Engine
  • For your 2003 GMC Sierra 2500HD with the 6.0L V8 engine, I highly recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13504. This 8000 series cooler measures 11" wide x 12" tall x 7/8" deep which will be a good fit for your truck. You can expect temperature drops anywhere from 20-30 degrees fahrenheit while using this cooler which will dramatically increase the life of your transmission. Installation is very simple as you can see in the attached video but you will...

This transmission cooler will work very well for your application and will simply connect between your radiator and transmission return line to further cool the fluid. I recommend using the Derale Snap-In Radiator Adapter Fitting for GM # D13035 to make this connection to your radiator easier with this manufacturer specific fitting. The...

  • Recommended Transmission Cooler for a 2006 Ford Expedition While Towing Through Mountains
  • For a heavy duty transmission cooler, I recommend the Derale Series 10000 Stacked-Plate Transmission Cooler Kit part # D13403 which as the name states has a stacked-plate design which is currently the most effective type in regards to a transmission cooler. This essentially means that you can install a cooler with less surface area and still receive greater cooling power like when compared to the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13504 for example. If you...

For your truck I recommend the Derale Series 8000 Plate-Fin Transmission Cooler # D13504. The rule with transmission coolers is the bigger they are the better they are going to cool, and this is an 11" Wide x 12" tall x 7/8" deep plate and fin cooler, which is more efficient than the tube and fin...

  • Recommended Transmission Cooler for a 2013 GMC Sierra 5.3L
  • I do have a transmission cooler option for you but they do not make a transmission pan for your 2013 GMC Sierra 5.3L at this time. As transmission pan coolers are typically not the most efficient coolers anyway I recommend using the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13504. The Derale 8000 is one of the largest most efficient plate and fin coolers we have for your vehicle and will provide your transmission with around 10-20 degrees of temperature drop depending...

  • In order to install a transmission cooler such as the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets part # D13504 on your 2013 Chevrolet Silverado without altering the factory transmission lines you would need to use one of the Derale Snap-In Radiator Adapter Fitting for GM part # D13035. The adapter will need to be installed on the transmission fluid return line on the radiator. The 11/32" transmission lines included in the above kit would be correct for your truck....

Fortunately, you have a good amount of room to mount an even larger cooler in front of the radiator behind the grill. The most efficient cooler for you vehicle would be the Derale Transmission Coolers part # D13504. You will also need the Yukon Hose adapter...

  • You currently are in a pretty safe zone for your transmission temperature. But if you wanted to maximize the life of your transmission going with a supplemental cooler like the Derale part # D13504 would be a great option. You'll want to install this cooler after your factory cooler and you'll get the best cooling capabilities. For an adapter fitting to make the process easier you'd want the part # D13035. You'll use your existing lines plus the rubber lines that come with the cooler kit.

  • Recommended Transmission Cooler for a 2004 Honda Pilot and 2006 Chevy Avalanche

For your Pilot I recommend using part # D13503 which is 11" wide x 8-3/4" tall x 7/8" deep and for your Avalanche I recommend using part # D13504 which is slightly larger at 11" wide x 12" tall x 7/8" deep. Either of these options will work well for you and provide your vehicle with adequate transmission fluid cooling. However, in order to install a...

  • Differences Between Derale Transmission Cooler Derale D13503, D13504, and D13502
