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 Review of Derale Transmission Coolers - Plate-Fin Cooler - D33502
Michael: Hi there. I'm Michael with etrailer.com. Today, we're going to take a quick look at the Derale Series 8000 Class III Transmission Cooler. This is one of the more popular cooling styles available. It's got the radiator style plate and fin heat exchanger, which provides that increased surface area so that the fluids can spread out along the vented chambers, so that as that cool air blows into your vehicle, you're going to have more surface area so that fluid will cool down faster, which is, of course, going to help prolong the life of your transmission. As we get cooler fluids flowing through, it's going to help that.
It's also going to improve your overall performance of your vehicle and, of course, prevent the heat related failures that are associated with overheating because we're going to have much cooler fluids flowing through to help keep that system cooled.In addition, to the increased surface area, this cooler also features a turbulator technology, which is going to agitate the fluids continuously so that, in addition to getting that heat transfer, it's also going to help prevent any undesirable drop in pressure, so we're not going to have to worry about that. This is constructed of a furnace brazed aluminum, and it's got the three quarter inch wide turbulator plates for that more efficient cooling and improved pressure. This is recommended for your medium sized cars or compact trucks and SUV's that are used for your light duty towing. It does have a gross vehicle weight rating of 17,500 pounds. It is specifically designed for your vehicles with the late model electronic overdrive transmissions.You can see, we are going to have two of these 11/32 inch hose barbs, so should be very easy to get connected and just put your hose over those and the fluids will flow through there and out the other side.
Our overall dimensions. Get a ruler here for you. We're looking at right about 11 inches wide. If we measure to the top of our piece here without the barbs, it's right about seven and a quarter of an inch. Might be kind of difficult to see that with the angle of the camera, but it is right about seven and a quarter of an inch tall without the barbs.
With the barbs, looking at closer to seven and three quarters of an inch. And it is only about just shy of an inch, about seven-eighths of an inch deep, so it's not going to take up a whole lot of room. The distance between our inlets up top here, going from center to center, we're right about 10 and a quarter. Get that lined up center to center, about 10 and a quarter inches.And then our mounting holes here across the top. We go from the center of the farthest hole to the center of the farthest hole.
We're looking at right about six and three quarters of an inch wide. I'll just measure on the back side here for the height. Again, center to center, we're looking at about six. Let me go down to this bottom one. Easier for you to see. Right about six and one-eighth of an inch from center to center of those. It should be pretty easy to get this mounted in place. It doesn't come with any hardware or anything, but you can just use some zip ties, depending on your application. Make sure that this is going to be mounted in place where you're going to get a nice flow of cool air flowing in so that you can cool down that fluid.This does come with a one year warranty from Derale, so it's nice to know they stand behind their product. If you have any problems, you can give them a call and they'll help you out. That's going to complete our look at the Derale Series 8000 Class III Transmission Cooler. Again, I'm Michael with etrailer.com. Thanks for watching.

Works fine and wasn't difficult to install. I didn't take the bumper cover off. Worked from top and below.
Fashioned an aluminum brace.

I did not test my transmission temps before installing this cooler, so it's very possible that it is helping -- just not enough. 4Runners are not great towing vehicles to begin with, so it's probably not this product's fault. It's fine on flats and gentle inclines, but on long steep inclines I still find myself hitting 260 degrees towing a ~3,000 lb teardrop. If you're towing with a 5th gen 4runner I would look into something bigger or one of the options with a fan.
by: Rahul05/08/2023
Very cool product! I can't seem to 'feel' the difference while driving, but when engine cold, the transmission shifts harder.....probably proof that the transmission fluid is not warming up as much
by: John G08/30/2013
Thanks for shipping so fast. the response time was impressive!
Below is a picture of the install of my Derale trans cooler (13503) installed in my 2010 Jeep Liberty.
I did not install with the inlet/outlet on the bottom due to thinking that with a plate and fin type cooler air might get trapped in other end. I mounted it horizontal and put the inlet flow on the bottom to assure that any air gets purged. Odd thing about this trans is that there is a bypass valve on the lines that is thermally operated. The flow to the coolers is bypassed until a specific oil temp is reached. Then flow is allowed to go to the cooler(s). This is done because the trans cooler is completely independent of the radiator. There is no thermal exchange between the trans fluid and the engine coolant. With the transmission fluid bypass valve in operation it is not possible to reduce trans temp below a preset level (or nearer ambient temp) because the thermostat valve simply turns off flow to the cooler(s).
In a conventional setup the coolant flows all the time and there is no by-pass. Trans fluid is kept from dropping in temp by the engine coolant which will actually put heat into the trans coolant if the engine coolant is warmer. Chrysler has no thermal exchange with the engine coolant so they thermostatically control flow to keep the trans from operation at a too low temp.
In short, in my vehicle I can’t reduce the trans temp below the thermostat setting, But I can assure that the temp of the trans can never be too hot.
I also mounted the trans cooler on brackets I made. I was uncomfortable pushing the rods thru the radiator and the air conditioning and factory trans cooler. The added mass of the Derale trans cooler may have been a little too much clamped onto the radiator. I tapped into the original hose with a 3/8 double barb fitting and double clamped all connections.
Also below is a exploded parts view showing the by pass valve on the trans lines which directs trans fluid back to the trans and by passes the cooler(s) until the trans gets to a specific temp. It is item #3.

Part seems to be okay. The hose is to short. Now I have to wait a few days to receive more hose to finish installation. etrailer should add more hose than the length that comes with it. On many applications this cannot be intalled effectively with the amount of hose in the kit. This is even mentioned in the video that etrailer provide.

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.
by: Stephen08/10/2023
Well constructed. Could use more hose for the install. I had to buy another length to install it. In the photo you can see I fabricated brackets for it so it would be able to get better airflow. Not noticing a real big difference in cooling but I’m anxious to see how it goes when I tow my 29 ft. TT with my 17 Suburban with a 5.3 ltr. I’ve been towing without one with no issues but any help in extending the life of the tranny is worth it.
by: Cory 04/25/2024
Wil need additional hose and brackets for my install. Will get local but would have purchased if I knew they were needed

09' silverado 1500 5.3
Temps are down 15 to 25 degrees on test drive, No trailer. 105* heat index city, highway, a.c running
75mph 169-171* (factory 185*+)
55mph 165*
City stops 159*-163*
Idle after drive for 10 min in Sun 149*
Trimmed factory grill mount and welded on tabs, to put back in factory location (no picture of finished grill mount by itself) used factory holes on upper grill hood latch assembly. Only fault is u need to remove trans cooler to unbolt grill mount, but it's just a grill mount.

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.

Have a 1998 Lincoln Mark 8 w/ 4 speed automatic which retails for no less than $ 4000.00 - Having this potential monkey on my back , I decided to invest in a trans cooler. Fabricated mounts and bolted on , used double flare connection to cooling line w/ barbed fitting ; barbed fitting @ radiator fitting. Used 2 hose clamps @ cooler, one clamp on each barbed fitting . Could only mount with fittings to left ,fluid leaves radiator , enters cooler @ top ( to reduce pump load ), comes out of bottom & returns to tranny. No trans temp. guage, but cooler gets hot @ idle, verifying cooler works . Well constructed and sturdy,easy to mount ; comes with instructions.

It’s been almost a year since I installed this transmission cooler. I would say it’s gone without a hitch, but THAT would be inaccurate. I also installed a hitch! I placed great confidence in this transmission cooler to do its job as my 2015 Honda Accord V6 served as my truck during our move this past year. Never a problem (ok, I’ll say it... It went without a hitch!).
etrailer customer service was EXCELLENT! There was a question during installation that arose from my particular model of car having a Transmission Fluid Warmer that in effect made identification of the transmission outlet and inlet reversed according to the instructions. The technician actually read and considered what I was saying, instead of just assuming the instructions applied to my vehicle. Thanks to their input, I correctly reversed the directions and got the correct solution!
BTW... I attached some pics of the correct hose routing for the 2015 Honda Accord V6. Note how you simply remove the short hose shown in the first pic, and connect the hoses from the transmission cooler! Note that I mounted the transmission cooler vertically so the hoses would reach. The last pic is showing the transmission fluid warmer (just as an FYI).

This does not fit a 16 Pilot Touring. The only option is the OEM trans cooler (500.00).
by: Esteban 10/02/2023
My teenage son and I installed this on our 2010 Suburban in about 2hrs. This was to supplement the tiny, stock external cooler. The video was very helpful. We did not have to cut the plastic as in the video. There was enough room for the hoses and fittings with no kinks. The transmission was running hot, 190-200 degrees with no trailer and up to 220 degrees with a trailer on level ground. The transmission never got above 155 degrees, with no trailer, after this cooler. I can't wait to tow now. I am confident the temps will stay at or below 200. This is just what I needed for my lifted Suburban and travel trailer.

I installed this transmission cooler about a year ago. Install went easy but I did have The bumper off as I was replacing the radiator. I think my temperatures are down by about 15°. The only reason I did not give it five stars is that I probably could’ve used a larger one.

Transmission cooler installed on 2003 Tacoma RWD.
The Transmission Cooler was easy to install. No problems whatsoever.
I chose to mount it behind & left of the license plate.
by: Eric09/09/2023
Great product, really helped keep my trans temp down. I deleted the thermal device on my suburban transmission (sorta like a thermostat) and coupled with this external cooler my trans runs an average of 50 degrees cooler when towing, sometimes more. Definitely worth it.
by: John 04/25/2024
First very easy to install. So for the quality is outstanding no wear or corrosion. Highly recommended
by: Scott06/13/2022
The hose that came in the kit was about a foot too short and should be 3/8 id. I had to source my own longer 3/8 transmission cooler hose. Other than that, the quality of the cooler appears to be good.
by: Rosemary06/23/2023
Although the website said this fit my car, it didn't. etrailer is good if you don't have to return anything. I've done a lot of business with them and have been satisfied but when I had to return this the return shipping was a third of the price of the item. Not good.

Transmission cooler installation on 2012 GMC Yukon 5.3L.
Top brace added for support.
by: Keith07/28/2014
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.

This cooler is working perfectly. It gives me piece of mind when I'm towing my old travel trailer. I didn't use the plastic ties that come with the product but instead mounted it with aluminum frame material from the hardware store. I was disappointed that the kit did not come with the adapter I needed to install it onto the transmission fluid lines on my Chrysler 300. I had to obtain the fitting from a salvage yard. The instructions were helpful.

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.
by: Fred05/26/2023
So far, no difference in temps running around town. Temps quickly ran up to 192 in low 90 degree weather. Not seeing the temp differences that others have posted about. 2014 Silverado 1500. True test comes tomorrow when I pull my 25ft travel trailer across country. Usually stays around 192 except in stop/start traffic. Then temps climb to 208 0r higher. This is why I bought this. And local repair shop charged me $474 to install it. Lot of money for no difference.
