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 Plate-Fin Transmission Cooler w/Barb Inlets Spec Review

Today we'll be taking a look at the Derale Series 8000 Plate-Fin Transmission Cooler with Barb Inlets. This is a Class IV transmission cooler and basically this is going to help to prolong the life of our transmission and improve the overall performance that we get from our vehicle by preventing any kind of heat related failures. This is going to cool down that transmission fluid as its flowing through our vehicle. A lot of times if you're trying to get the most out of an older vehicle, maybe it's seen a few years and it just needs all the help it can get or you're using your vehicle to do some medium to light duty towing. This is going to help to make sure that we don't have to cut our vacation short or cause any delays by having to deal with a overheated engine.So it's the plate-fin style, it's going to be the plates running across there. Those are turbulator plates for more efficient cooling.

They're 3/4" wide. Turn it to the side, those are 3/4" wide there and then we'll have all the fins sort of running back and forth like little ribbons in there. That helps to increase the overall surface area to cool everything down more efficiently and a lot quicker than we typically get from our transmission as it is.This is recommended for medium to full size cars and intermediate SUVs that are again going to be doing some light to medium duty towing and just trying to get the most out of those vehicles. We'll have our inlets which are 11/32" hose barbs. The gross vehicle weight rating for this is 20,500 pounds.

As far as the overall dimensions, it's about 11" wide from the outside edge of those inlets, and then if we turn it on to the side from the top of the inlet to the bottom of that cylinder, it's about 8-3/4" tall. If we go from the top of the inlet to the bottom of the mounting flange, it's a little bit longer and that would be about 9-3/4", or about 9-5/8".Our thickness overall, it's about seven eighths of an inch to that outer cylinder. The distance between the inlets, center to center, is about 10-1/4", and then for our mounting holes, the distance between those at the widest point, center to center, again it's about 6-3/4", and then for the two narrower ones it's about 5-1/2".If you want to get a complete installation kit that comes with a hose and some mounting hardware, you can find a lot of options available here a etrailer.com. One of those would be Part Number D13006, that's going to come with some of your 3/8" hose that can withstand the heat of that and also some rods and other hardware to get this installed.Again, there's a lot of different configurations out there, so definitely search around at etrailer.com to find the right configuration for you. This does come with a one-year warranty.And that's going to do it for our look at the Derale Series 8000 Plate-Fin Transmission Cooler with Barb Inlets..

A very good product,installed very easy and keeps the transmission cooler while towing.

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:

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.

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.

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.

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.

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.

This fits my 2009 tahoee 5.3 liter engine. Fit on triangular support in front of ac condenser. Need the bendable brackets. Look at the vid for 2009 Yukon install.



by:

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:

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:

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:

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.



by:

I added this to my 2011 Silverado because I pull a 24Ft camper and when it's hot out the trans temp would get quite warm. Since I added the new cooler this is no longer a problem. It runs much cooler and when it does warm up some it cools off much quicker. Very happy with it! I highly recommend it.

Was a confusing install better directions on where to connect would have helped for a novice but performing welll

Fast shipping!! Great communication from pur hase to doorstep!!

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).

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.

I had it professionally installed by my mechanic, as it would have been much more difficult if I had done the job, as I don’t have the tools and expertise. Seems to work well. No issues. Glad to have made the purchase.

I always enjoy my experience buying from etrailer. Troy my sales associate was very knowledgeable about the product and ensured I had all the parts i needed to complete my install. On most online sales transaction the sales associate is done when the order is placed, not so at etrailer, troy followed up with me to ensure i got all the products i bought.

Installation was easy as etrailer has very good videos, makes me look like a pro, in my case I utilized the video on the chevy suburban to provide the basics for my silverado installation. The difference between the two is the silverado front grill snaps out and i did not have to drop the entire front cap. ALso had to fashion a mount for the cooler to support it to the A post. I just used two bolts and locknuts together with the two pieces of the bendable metal mounts (D13002). see photo.

I took my trailer out this past weekend to test out the cooler. My transmission runs at least 20 degrees cooler while towing my 8000lb 5th wheel trailer. Max temps were at 160 deg. with air temps at 91 degrees, and high humidity in florida, typically this would be in the low 180’s rolling at 60 mph. transmission felt smoother while changing. I have a performance tune on my truck. Accelerating off the on ramps did make the transmission temp rise above 160 to around 165 then it fell back to around the 160 mark. It started raining heavily and the outside temps dropped to the 80’s and the transmission temp dropped to the 140’s.
Normal driving around town with no hitched load in stop and go traffic with outside temps hovering around 95 with high humidity (feeling more like 103). here in tallahasse my transmission runs at around 140. I just checked my owners manual and my transmission oil and filter is past due for changing. i will get that done and see if anything changes. all in all this product works for me.
Thanks etrailer!!!

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.

The D13503 transmission cooler was a fairly straightforward DIY installation on a 2010 (3rd gen) Honda Odyssey. Watch a video or two on etrailer.com and you should be able to figure everything out. Two issues came up. First, it is not trivial to get the hose pushed securely onto the nipples of the cooler or the vehicle. Readers should thoroughly lube the inside of the hose and the outside of the nipple. (I suppose a tight fit is good, just be prepared to apply force and be patient!) Second -- and this is why the product only gets 4 stars from me -- the head of one of the plastic mounting rods broke off. No extras are supplied, so I figured out a zip-tie solution. It leaves me nervous about the strength of the remaining three, but the installation seems secure for now.

Potential DIYers should also note that you are likely to break some of the body panel retainers (aka "clips") during disassembly of your vehicle's front end. (Not surprising on my 95,000 mile van; they were brittle.) Be prepared and locate a source for replacements ahead of time.

Overall, this product seems well-designed, is offered at a great price from etrailer, and has the potential to lengthen the life of your transmission even when not towing.

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.

The cooler is well built and the included hardware are high quality. I installed it on a 2014 Nissan Pathfinder with CVT. I have the factory external cooler but in a Texas summer, it just wasn't enough. I added this cooler in line. My reasoning: the factory cooler has a thermostat bypass valve (the little metal box the transmission lines go into), so to allow the heater and bypass valve to work without constantly cycling. here is how I connected everything. Hot fluid comes from the transmission to the factory cooler via the top hose. It then goes through the factory cooler or bypasses via the valve depending on fluid temp. It comes out the bottom line which I ran to the top nozzle on the Derale cooler. You can see where I drilled 2 3/4" holes in the plastic for the lines to go through. The bottom line goes to the return line on the radiator, and cool fluid returns to the transmission (The factory hose is just long enough to reach the new cooler where I positioned and mounted the new cooler, otherwise I would have had to buy extra hose). The mounting straps that come with the new cooler are plenty strong, judging by how much I had to fight the hoses. Also, I mounted the new cooler to the air conditioner condenser, the condenser is held on with 2 bolts, and unbolting you can get just enough clearance to reach behind it to tighten the straps. So the straps don't go all the way through to the radiator, so I didn't have to remove the electric fan. The hoses are loosely zip tied to each other, so they don't touch the air dryer. Some people say it doesn't matter how you position the external radiators but this is false. Radiators are design to take in the warmer fluid on the top and the fluid cools as it goes down (heat rises, cold falls). This allows for better circulation on systems that don't have an active fluid pump. This is also the most efficient configuration and since the transmission breather sits on the top size of the engine, it also reduces the chance of air sitting in the system. I didn't find any good installation videos or reviews that really explained how they installed their cooler. So I hope, along with my photos, this helps some of you.

  • Replacing Derale D13503 Transmission Cooler 2014 Honda Odyssey
    You can certainly replace your existing Derale Series 8000 Plate-Fin Transmission Cooler # D13503 with the Transmission Cooler # D33503. In fact this is the same exact cooler you currently have but it just doesn't come with the install kit and radiator adapter so it has a different part number. If you are looking for a more efficient/larger unit than what you currently have I recommend the Derale Series 8000 # D13504. This is a similar plate-fin style cooler than your current unit but...
