2013 Honda Odyssey - Derale Dyno-Cool Tube-Fin Transmission Cooler Kit - Class I - Economy

  • Tube-Fin Cooler
  • With 11/32 Inch Hose Barb Inlets
  • Standard Mount
  • 13W x 5D x 3/4D Inch
  • Derale

13" Wide x 5" tall x 3/4" deep, reliable, all-aluminum tube-and-fin cooler extends the life and improves overall functioning of your Honda Odyssey's transmission.


  • Improves functioning and overall performance of transmission
  • Extends life of transmission and prolongs period between necessary fluid changes
  • Cuts down on heat-related failures
  • Agitates fluid with built-in, embossed turbulators for more efficient cooling
  • Constructed of durable, lightweight aluminum
    • Thermal-conductive metal provides excellent transfer of heat
  • Includes:
    • High-temperature, OEM spec hose with stainless steel clamps
    • Nylon mounting rods
    • Insta-dapt radiator adapter
  • Recommended for subcompact cars
  • Imported


  • Inlets: 11/32" hose barb
  • Overall dimensions: 13" wide x 5" tall x 3/4" deep
  • Core width: 10-1/8"
  • Distance between inlets: 3-3/4"
  • 1-Year warranty

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.

Perhaps the simplest type of heat exchanger, the tube-fin effectively cools a variety of automotive systems. The concept is simple: Fluid cools as it travels through the core by transferring heat out to the fins. The fins then provide the surface area necessary for sufficient heat exchange to take place, allowing the heat pulled from the fluid to dissipate into the surrounding air. Quick, easy and effective.

13" Wide x 5" tall x 3/4" deep, reliable, all-aluminum tube-and-fin cooler extends the life and improves overall functioning of your vehicle's transmission.


Great product. Easy to install. Drove cross country and the transmission kept its cool. Even through the mountains in warm weather. No signs of leakage or corrosion after a year.

2001 HondaOdyssey

I installed this cooler on a 2001 odyesseyto help prevent a future trans failure.It was delivered quickly when promised,came with everything I needed for installation and had no problems.Overall a good product I would recommend this to anyone.
I am also very happy with etrailer.coms service and selection and would definitly use them again.

Subaru Forester

As always, fast delivery, complete products that fit right at the best price anywhere. Everything I needed to turn Mom's Forester into a tow beast (for a pop up camper anyways)!


Two cars, two transmissions radiators, very good product from
Thank you !


good product at a very good internet price, thanks

2008 Honda Pilot

This is an excellent price and appears to have more cooling capacity over the OEM cooler. Installed very easily. This was used on an 08 HONDA PILOT

1996 Chevrolet Astro

I received the trans cooler yesterday afternoon and installed it on my 1996 chevrolet astro this morning in less than an hour, now I can pull my travel trailer with my van.


The product was just what I needed. The description was accurate, the price was great and the shipping was fast.

Great, no problems

Review from a similar Dyno-Cool in Transmission Coolers

I have always loved etrailer and their service. Once again order another of these coolers. Drop my temp from 240 to 170-190 also remember to order extra hose, the adapter if needed for your vehicle make, mount kits. Love it. Perfect this one is on a 07 GMC Yukon XL always add an extra cooler on your 1500 gmc or chevys they help out so much for them.


Review from a similar Dyno-Cool in Transmission Coolers

Great cooler upgrade for my 1997 GMC Yukon! Little delivery damage, but was so easy to bend those fins back to original shape so no worries!
Nice that you had proper dimension measurements online, so it was easy to figure out what kind I can fit in my truck. Complete kit had everything I needed to get it done!
Modified old cooler bracket little bit and that was it. Works great!


Review from a similar Dyno-Cool in Transmission Coolers

I just installed this on my chevy avalanche.
the bottom brace around in order to mount to.
The hardest part is getting the hoses on the cooler and over the return line.
I ended up getting a 90 deg quick connection coming from the radiator instead of using the one I got from etrailer. This keeps the hose from bending as much.
Also purchase the installation kit with a hose as you will need an extra hose.
After install I wish I would have went with the next bigger unit which is 10 high instead of 7 1/2 as I had plenty of room.


Review from a similar Dyno-Cool in Transmission Coolers

Not sure of the btu output of this but it worked perfectly fine in my jeep with the factory transmission. Upgraded to a built transmission and as it seems ill need a lot more cooling capacity. No rust or corrosion so far. The clamps it ships with are a gigantic transmission hazzard... had a clamp split right down the middle on me in my drive way thankfully. I would buy different clamps if you didn't want fluid puking out of a hose at 90+ psi and kill your trans.


Review from a similar Dyno-Cool in Transmission Coolers

I installed this fan yesterday. Very powerful and works great. Currently works off a selectable switch as I need it but will switch out with the thermonswitch I got soon.


Review from a similar Dyno-Cool in Transmission Coolers

good product form a great company !
only complaint is this was listed as for my specific truck, but the "insta-dapt" supplied doesn't fit the Dodge truck of my year. even doing my research ahead of time, it seems to be hit or miss whether it would fit as some of them come with 5/16 fittings and some (like mine) come with 9/16 fittings. it doesnt matter the engine size, even other 3.7L dodge trucks of the same year have 5/16 fittings... I think Dodge made a change middle year, but never let the consumer know as mine is a late year '04.
no dig deal as I was able to assemble it anyways and got it up and running great and both the radiator and trans are running much cooler now !
I attached the D12902 to the bumper as you will see in attached images.
2 attached images are just before finishing, bumper hasnt been attached yet, one of them is after everything was complete.


Review from a similar Dyno-Cool in Transmission Coolers

We use these fans in a training mechanism that is used in colleges and vocational schools,they hold up very well under repeated usage.


Review from a similar Dyno-Cool in Transmission Coolers

This fan looks like it will do a great job.
more overheated transmission.
Pulling a trailer in stop and go traffic on a 100 degree day - No problem :-)


Review from a similar Dyno-Cool in Transmission Coolers

I purchased this for my C6 Corvette A6 transmission. I did, however, bypass the radiator and only use the transmission cooler for the C6. I purchased and used the Derale Radiator Adapter fitting 259-13035 for both the top and bottom and just capped them off to keep debris out of the reservoir. I also had to make some custom mounting brackets. This is an excellent product and it keeps the tranny in a great temperature range.


Review from a similar Dyno-Cool in Transmission Coolers

Works well. Just make sure it is matched to the load being towed.


Review from a similar Dyno-Cool in Transmission Coolers

Installed this in a 2017 Honda Ridgeline. Mounted it above the factory cooler that was already in the truck. (Flat fin side towards the a/c condenser). I used the insta-mount zip tie kit and also the flex metal mounts to anchor the cooler to the top of the factory cooler bracket as close to the a/c condenser as possible. The vertical bracket (part of the truck) that runs right down the middle of the a/c condenser has to be cut. All fairly minor fabrication. Hack saw and hand drill stuff. The fan has to be reversed to become a pusher. Followed the hood release cable from the interior to run 12 volts to power the fan on at ignition. Haven’t hooked the trailer up yet so I don’t know if this will resolve the hot tranny situation. ( I could smell the tranny getting hot before especially when we stopped at lights). Change your fluid too. etrailer delivered quickly and the cooler was well boxed and untouched.

We towed our travel trailer 7500 miles last fall almost coast to coast and back. The trailer weighs 4400 lbs loaded. The Ridgeline’s towing capacity is 5k lbs. I kept our speed at around 65 mph. The truck was capable even in mountain terrain. The transmission never overheated. I did change the fluid once during the trip and again when we got back. The cooler worked. Never once did I get that burning smell. I’m almost certain that the cooler saved us a huge overhaul repair. Thanks etrailer.

Review from a similar Dyno-Cool in Transmission Coolers

I used this cooler on a 2004 Chevy Silverado. The accessories were not needed because I needed longer hoses and fabricated my own mounting. I think the hose clamps and the hoses could be better quality. The cooler does work very well.


Review from a similar Dyno-Cool in Transmission Coolers

Can't say anything bad about the unit. It was installed in a Jeep Grand Cherokee that I use to haul trailers occasionally that weigh up to 6000 lbs. So far, I've never overheated the transmission at all, which I attribute to the addition of this cooler. Once again, thanks for a great product.

  • Optimal Mounting Location for Transmission Cooler on 2006 Buick Rendezvous
    The best spot to install the transmission cooler is in front of the radiator, where it will get maximum air flow. If necessary it can be mounted behind the radiator, if there is sufficient clearance for installation. Installing the cooler in front of your radiator would almost certainly involve removing the grille and possibly the front fascia under the bumper to improve access. We have an installation video showing a cooler being installed on a different vehicle, watching the video...

  • Does the Derale Transmission Cooler for a 2001 Honda Odyssey Come with Installation Instructions
    The transmission cooler # D12901 does come with installation instructions. Since transmission coolers are not vehicle specific, the instructions will not cover any individual vehicles. The output from the transmission will first run to the factory cooler which is mounted inside the radiator. The return line will then go to the supplemental cooler, and from there back to the transmission. A cooler can be mounted in basic locations depending on the space available. The most efficient place...

  • Would the Derale Transmission Cooler part # D12901 be Adequate for 2007 Honda Odyssey Towing Pop Up
    Transmission coolers like the part # D12901 don't really have weight ratings. We put them in classifications based on size and the general cooling efficiency they would have. The part # D12901 would work just as good towing a 2,000 lb trailer as a 2,100 lb trailer. This will work just fine on your 2007 Honda Odyssey.

    The # D12901 is a fit for all engine options on the 2016 Ford Escape Titanium. For your Escape this measures 13" wide x 5" tall x 3/4" deep so you may want to check under the hood to make sure you have the room needed for this cooler. Also 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. Included is a video resource, instructions,...

    Transmission coolers are flow through devices so you can pretty much use any transmission cooler you want as long as it will fit in your vehicle, which is why it's always a wise decision to measure the space where you plan to install it before purchasing. The optimal location to install a transmission cooler and where you want to measure is in front of the AC condenser.

  • Which Class Transmission Cooler Should be Used on a 2006 Honda Odyssey
    Derale adds Class information to try to make it easier to select the proper transmission cooler for a given vehicle. It is supposed to match the Class of the trailer hitch you have. But really, transmission fluid cannot be over-cooled so going with the largest cooler that will fit is the way to go. The most popular option for a 2006 Honda Odyssey is a Class III cooler # D13502. It is 11 inches wide, 7-1/4 inches tall, and 7/8 inches deep. I have linked a video showing an installation on...

  • Transmission Cooler Recommendation for a 2008 Chevy Uplander
    Transmission coolers are not vehicle specific so you can use any one that will fit in the space you have available in the engine compartment. There are 3 locations you could mount the cooler: in front the A/C condenser, behind the condenser and in front of the radiator, or behind the radiator which is not very efficient. Check these areas for how much space you have to make sure a cooler fits. The most popular cooler is # D13503. It measures 11 inches across, 8-3/4 inches tall, and 7/8...

    The Derale 17" Frame Rail Fluid Cooler, # D13221, is a universal cooler so it will fit your 2004 Dodge Dakota but does not include the fittings and hose that you will need for installation. Instead, I recommend taking a look at Derale Dyno-Cool Tube-Fin Transmission Cooler Kit, # D12901. Still very economical but offers a larger cooler and includes a high-temperature hose with clamps, nylon mounting rods, and Insta-dapt radiator adapter which fits most vehicles with 5/16" transmission...

  • Replacing the OEM Transmission Cooler on a 2012 Jeep Grand Cherokee
    The transmission coolers that we have on our site are meant to be supplemental coolers, meaning they are meant to be installed on a vehicle that has a transmission cooler that is in good working order.

  • Is Transmission Cooler Recommended for 2019 Nissan Pathfinder Towing Within 500 Lbs of Max Capacity
    You're getting pretty close to the towing capacity of that vehicle, so yes I would without doubt recommend a transmission cooler. A transmission cooler is some super-inexpensive insurance that will do a great job of protecting your transmission. The best place to install a cooler is right behind the grille, in front of the radiator. You'll want to choose a cooler that fits the available space, and you needn't worry about the cooler blocking the air flow to the radiator. There's enough...

  • Transmission Cooler Options and Installation for a 2009 Chevy Equinox Pulling a 2,800 Pound Trailer
    I am not sure what, if any, benefit new cooler lines would offer. But the right transmission cooler will do the trick. If your 2009 Chevy Equinox has the 3.4 liter engine, we have several options. I recommend the Derale Transmission Cooler, # D12901. This has the simplest, tube fin design. It is fairly small so it should be easy to find the best mounting point. There are essentially three places to mount a transmission cooler. The best place is between the grille and AC condenser core....

  • Transmission Cooler Recommendation for a 2005 Acura MDX Towing a 3,750 Pound Boat and Trailer
    The Class of transmission cooler you use will depend more on where you can mount it. The most efficient place is in front of the AC condenser. You could then use a Class I cooler, like # D12901. If mounted behind the condenser, I would go with a Class II like # D12906. If mounted behind the radiator I would go with a Class III like # D13502. The problem is that the further away from the front of the vehicle a cooler is mounted, the less airflow it receives. The less airflow a coolers...

  • Transmission and Power Steering Cooler Recommendations for a 2007 Honda Odyssey
    Many car manufacturers will state that a transmission cooler and/or power steering cooler is needed when towing in order to protect the transmission and power steering pump when under load and to be in compliance with warranty requirements. It is always a good idea to use a transmission cooler and power steering cooler when towing, even if the load is a light one.

  • Is a Transmission Cooler Required when Just Carrying Bikes on a 2015 Honda Odyssey
    No, a supplemental transmission cooler is not going to be required if you aren't towing a trailer with your 2015 Honda Odyssey. But adding a cooler certainly would not hurt since transmission fluid cannot be overcooled and it will help you to get the longest life out of your transmission. Even a small one, # D12901, will help.

  • Transmission Cooler and Suspension Enhancement for a 1995 Plymouth Voyager
    A transmission cooler would definitely be a good call for your 1995 Plymouth Voyager since the factory cooler by itself is adequate at best for non-towing situations. The best way to pick out a transmission cooler is to measure the amount of space you have in front of your radiator and pick out the largest cooler that would fit there. If you have room for it I would recommend you go with a Derale Transmision Cooler part # D13502. This cooler measures 11 inches wide by 7-1/4 inches tall...
