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.

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

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

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

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

2013 Chevrolet Colorado

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

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. .

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!!

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

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

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

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 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

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 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 been towing my inboard boat all summer and the cooler is doing a great job which I can tell because I have a transmission temperature gauge. The hottest it ever gets is 205 degrees when going uphill.

I’ve had the Timbren suspension enhancement system for a year now on my ‘99 Dodge 1500 4x4. I purchased this product because I had to tow my bumper pull three horse trailer from South Carolina to N. Central Montana. With a camper top, the bed loaded and the trailer loaded the truck sagged really bad. With the Timbrens on the sag went away completely. Making for a much safer less stressful experience while towing. 772867

WHAT A COMPANY!! I can look over the products and select the best part I could afford, and the best part is they have people that actually TEST the parts they sell. I settled for a complete hitch towing setup for my 2011 Chevy Express van: a class V receiver, 4 way and 7 way harnesses and a trans oil cooler. Everything was spot on, even the shipping.... employees researching and testing their products - what a concept?! I have other towing products I will need to get and they will be from etrailer.

Hardly any difference in flat land driving temps. Perhaps 5°to 10° cooler is all. Pulling my 10K camper any grade at all and temps still climbed. Mountain passes on any day over 80° , the trany still gets over 200° quickly. On the plus side the cooler seems to recoupe quicker than the stock one. 2009 Chevy gasser . 738567


Comments
A normal operating temperature for your transmission fluid is between 175-225 degrees F. Adding a transmission cooler effects every vehicle differently based on a number of conditions - such as if youre towing, how heavy a load youre carrying, the outside temps, etc. From what youre describing it sounds like the results youre seeing are keeping your transmission running within that normal range. Even while towing close to your max capacity over the mountains on a warm summer day, your transmission fluid is still at the sweet spot of 200 degrees F.

A supplemental cooler can decrease the temperature significantly due to more airflow to the fluid and more capacity (fluid) in the system.

    You currently are in a pretty safe zone for your transmission temperature.

  • 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...

  • Transmission Cooler Recommendation for 2019 Chevy Express Van
    Transmission coolers make a huge difference in the longevity of a vehicle transmission. Basically the biggest one you can fit will give you the best performance. For your 2019 Chevy Express Van I recommend the Derale cooler part # D13504 which measures 11" Wide x 12" tall x 7/8" deep and is a very efficient style of cooler. This is a plate-fin style which does a much better job than a tube fin style. I attached an install video that shows this cooler installed on a similar GM SUV as...

  • Installing a Transmission Cooler on a 2010 Chevy Avalanche
    There are a few transmission coolers that fit your 2010 Chevy Avalanche and the price will vary. I included a link showing you all the transmission coolers we currently offer for you to look at.

  • Recommended Transmission Cooler for a 2016 Subaru Crosstrek
    I spoke with my contact at Derale and they informed me that there is no reason as to why an aftermarket transmission cooler would not be compatible with the CVT transmission in your 2016 Subaru Crosstrek. I recommend using the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets part # D13504 as this will be an excellent option to bring down the transmission fluid temperatures in your vehicle while towing. As long as you have 11" wide x 12" tall x 7/8" deep of space in...

  • How to Install a Transmission Cooler on a 2008 GMC Yukon XL
    If you take a look at the attached install video on a similar 2009 GMC Yukon XL. You will see that the line that attaches to the upper right hand corner (passengers side) of the radiator is the return line and will be used to install the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13504. However, it is always good practice to start the vehicle and let it warm then grab each of the transmission lines that go to the transmission. The colder of the two lines will be the return...

    On your 2007 Chevy Suburban with the 5.3L V8 you can install any transmission cooler that can fit in the available space in front of the A/C condenser. This is the best location to mount one. Coolers are not vehicle-specific so any cooler for which you have sufficient mounting space can be installed so long as the transmission has external lines to allow you to tap into the system. Larger coolers work better than smaller ones so a unit like the efficient Class IV Derale # D13504 along...

  • How to Determine Which Transmission Line is the Return Line on a Vehicle for Installing Cooler
    An easy way to tell which of your transmission fluid lines is the return line is to wait for the truck to be cold, then start it up and shift into drive for about 15 seconds and apply a bit of throttle with the brake firmly applied. Then put it back in park and turn off the truck. Then under the truck carefully touch the transmission lines. One will be noticeably warmer. So that makes the cooler one the return line.

  • Recommended Transmission Cooler for 2010 Chevy Avalanche 1500
    When choosing a transmission cooler, the best practice is to go with the largest and most efficient cooler that will fit in the available space. The ideal mounting location for a transmission cooler is directly behind the grille, in front of the a/c condenser and radiator. If the available space will accommodate the 11 by 12 inch by 7/8 inch thick size of the # D13504 you mentioned, the # D13504 would be your best choice.
