Derale Transmission Coolers - D12904

15-1/4" Wide x 10" tall x 3/4" deep, reliable, all-aluminum tube-and-fin cooler extends the life and improves overall functioning of your vehicle's transmission.


Features:

  • 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 full-size cars, trucks and SUVs
  • Imported


Specs:

  • Inlets: 11/32" hose barb
  • Overall dimensions: 15-1/4" wide x 10" tall x 3/4" deep
  • Core width: 12-1/4"
  • Distance between inlets: 8-3/4"
  • 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.

Video Transcript for Derale Dyno-Cool Transmission Cooler Installation - 2002 Chevrolet Silverado

Today in our 2002 Chevy Silverado, we'll be installing the Derale Dyno Cool Tube-Fin Transmission Cooler Kit part number D12904.To begin our install, we'll first go ahead and open up the hood and then remove the core support cover. Core support cover is a plastic cover that goes over the core support and held in with push pin fasteners. Using a flat blade screw driver, we'll inaudible 00:00:26 the fastener up and then remove it completely. There are multiple fasteners holding it in place. This is a twist lock connecter. We'll go ahead and rotate it. Unlocking it, we remove the fastener from the position that's being secured.

Now we have 3 additional twist lock fasteners removed, 1 on the top on the other side and 1 on the bottom of each corner. Then, we'll remove the center fastener which is a bolt fastener going into the core support. Now, we have 2 remaining fasteners out on the corners on each side. You can use a flat blade screw driver, an interior trim panel tool or you're going to a use a little plastic pry bar. Now that we've released all the fasteners, we can go ahead and remove the grill completely and set aside for reinstallation later. Now for this application, the manufacturer already has a small external cooler installed so we can test the lines to find out our hot and cold side if we want to install the new cooler in series or in line with the manufacturer's cooler.

To do that, we're going to start the vehicle. As we start the vehicle and the transmission fluid warms up, we'll feel the steel line to see which one heats up first. Now for this application, the line here on the passenger side is our hot or pressure side and the driver side is the cool or low pressure side. Now we've identified which line we're going to tap into, we'll need to mount the cooler. To prepare mounting our cooler, we'll go and set it in position here in front of the radiator and AC condenser. Give myself a little more working room, we're going to ahead and cut a notch into the pre-drilled hole so we can slide it more to towards the center of the vehicle. We're going to cut out this section right here.

Now you could use a cutoff wheel or even a pair of tin snips will get through this plate. Now my cutout made, I'll go ahead and set it in position and install my fastener here in the frame bracket right here below the pre-drilled hole into the steel to help hold it in place. Just using a self-tapping screw, we'll go ahead and secure our cooler into position. Now with our fastener holding our cooler, we'll need to add some bracketing to secure the other 4 corners. We're going to use the Derale universal bendable mounting kit part number D13002. We can take the bendable mounting bracket, put it in a position and then bend it as necessary so we can secure our cooler.

I'm going to go ahead and take one of the self threaders provided with the install kit to secure the top of my bracket. Now with my mounting bracket secured, we'll go ahead and flex the cooler and bracket to line up with the pre-drilled hole. Once we have them lined up, I'm going to install a bolt and flange nut to hold in place. We'll just install it finger tight this time. For the bottom one, we'll go ahead and take our bracket, bend it in position. We're going to install our bolt and flange nut on the bottom of the cooler, then secure the bracket here to the headlight support. We'll need a pre-drilled hole here in the bottom support bracket. To drill out our hole, we're going to use a smaller inaudible 00:04:54 and then open up to our larger size using step bit process. Now before I install my fourth and final bracket because we've already got our hole pre-drilled out, I'm going to go ahead and remove the fasteners that are securing it so that we can install the oil cooler hose and then reinstall it and then finally secure it. Now, install the new lines provided with our install kit onto the end we'll go ahead and remove the protective cover and then we're going to apply a little bit of the transmission fluid to the end of the tip and the hose to help it slide on easier. Once we have the hose in place, we can then go ahead and secure with the hose clamp provided with the install kit. Now on this application where I put my hose onto the other side, we'll go ahead and feed it through the hood release bracket here. This will allow me to get my cooler back into position and mount it before we disconnect the manufacturer's cooler lines. Now with my hose routed, go ahead and install the clamp. Then we'll install our second hose onto our new cooler. Once we have the hose on, we go and tighten down our line. Now with the line tighten down, we'll go ahead and install the cooler and secure it in its position. I won't fully tighten down the bolts and nuts until we have them all in place. As we see here, the pre-drilled holes in our bracket do not line up with the pre-drilled holes and the mounting clamps for the cooler so we'll just take a couple of self-tapping screws and go through the bracket then through the cooler clamp. We use a self-tapping screw provided with our bracket kit. With our first fastener in place, we'll go ahead and repeat the same process with the second fastener. Now, go back and tighten 3 bolts and nut fasteners. Now with all the fasteners tightened down, we'll go ahead and check to make sure our cooler is secured. Once we're confident it's secured, we'll then go ahead, move over to our hose and transmission cooler line. With this application, we can remove the manufacturer's quick disconnect fitting. To do that, well first, you need to remove the protective cover holding the clip in place on the manufacturer's side. Over-tying this can become brittle so we'll be very gentle with the plastic clip. Once we have it removed, we can see a smaller metal clip underneath. We'll need to remove this clip in order to remove the line from the cooler. Now, the snap ring out of the way, we're ready to remove the manufacturer's transmission cooler line from the cooler. As you can notice, over time, the line will build up rust dust here and debris and can be difficult to remove. Then, we'll go ahead and work a pick around the fitting just to try and break some of that rust loose. Then, we'll tap the line out. Now with all line out, we'll go ahead and put our new fitting in place. For GM vehicles part D13035, then we can install the snap ring to hold in position. We'll reuse the manufacturer's snap ring that we removed earlier. Next, we'll take the plastic clip off the old line install it under the new fitting. Now with our new fitting in place, we'll have our 2 connection points for the new hoses to fit. Now, we can go and take the hose, route it, mark it and cut the line. Using a pair of tin snips, we'll go ahead and cut the hose to fit. Go ahead and check my routing and before we install it under the new fitting, we'll install our hose clamp. Once the hose clamps on, we can put the hose onto the fitting. Move it into place and then tighten down our hose clamp. With 1 side down, we'll repeat the same process with the other side. We'll route it over to the fitting or in this case, the manufacturer's line. Once we got it routed, go ahead and slide our hose clamp on and then put the new hose onto the manufacturer's line. Because of the flaring in the line, there's no need to make any adjustments. Once we get our hose onto the line, we'll then go ahead, tighten down our hose clamp. Now to help protect our hoses that goes around the cooler here, we're going to install the spectrum half inch wire loom part number 459075-1 and we're going to use about 10 to 12 inches of the wire loom. Next, we'll go ahead and use some zip ties to secure the hoses as necessary. Now we have the hoses secured, we'll go ahead and cut off the excess from zip ties to clean up our install look. At this point, its a good idea to go ahead and start the vehicle, warm it up, bring it up to operating temperature and pressure and check for any leaks. At that time, you can also tap off the transmission fluid as needed. All right. Now that we've checked for leaks, we're ready to go and reinstall the grill. Now we've put our grill back in place, we'll just resecure with the manufacturer's fasteners. Then our front core support cover. Now that we have everything reinstalled, this complete the install the Derale Dyno Cool Tube-Fin Transmission Cooler Kit part number D12904 for our 2002 Chevy Silverado. .

This is a customer service review not a product review. Leeza J. was very helpful in helping me get everything needed for adding a secondary transmission cooler to my Chevy truck. I ordered 3 different items and the one item was not in stock and I was promised that I would be notified when it arrived. I was notified that the item was in stock 2 days later and I received the package a few days after that. Very good service that impressed me. 377288

Super easy install. With the installation video on Youtube it took out any of the guess work. The hose could stand to be about 3" - 5" longer if you are going to center in the A frame of an older chevy grill (I have an 06 Avalanche. I had to offset to the passenger side to use the supplied hoses) But, you can get a longer hose easy enough. Just ran over the pass and back and no leaks. Looks good so far! 377410

i put this unit in my 2008 NIssan Titan pickup. we are going to take a 9000 mile trip this summer pulling a 27 ft HI Lo camper. The instructions were very generic. specific unit instructions would be very helpful. the grill was difficult to get out until i found a Youtube video for that. the hose provided was to short, so I made a run to the parts store. the unit appears to be well made. 368894

Easy install. But hoses need to be longer. I had to go to napa to purchase an extra 3 ft. The hose clamps that were included were limited to the amount of tension that were put on them. They would tighten to x amount then just spin. I had to purchase extra hose clamps that actually tightened. Impressed overall. 64593

Review from a similar Derale Dyno-Cool in Transmission Coolers


This product is great and installation was not bad at all. Only issue I had was that the GM radiator adaptor should come with this unit when you purchase it for a GM truck. Not as an add-on. Thought I could get it at GM but no go. I Had to work with hoses over 30 min to get them over the fittings even with trans. fluid on the hose and male fitting. So far it looks like trans temp has dropped 30 dg. 134485

What is the rated towing weight for a 1999 Honda CR-V? Does a trannie cooler install fairly easily on the Honda CR-Vs? What is the most effective mounting location for the finned cooler? How does the addition of a trannie cooler effect the volume of fluid and fluid level reading on the dip stick? Thanks for your time and expertise.

-- comment by: Robb B - 10/22/2013

The towing capacity question is a loaded one. For that, I would refer back to the owners manual. It can vary depending on engine, transmission, drive configuration and more. Furthermore, Honda has some very specific guidelines regarding towing so it's best to defer to them. Installing a trans cooler on a full size truck can be easier because of the extra space, but it is not particularly difficult on any vehicle. We actually have a video of a cooler being installed on a 2006 C-V. We remove the front bumper cover for the video, but you may find you do not need to. (See link). The most effective location will be in front of both the radiator and the A/C condenser. As you move behind each cooling device, the efficiency diminishes. We put ours in front of everything on the 2006 in the video. For fluid capacity, plan on an extra 1/2 quart. Depending on cooler size and construction, it will vary some, but 1/2 qt. is a good rule of thumb.

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. 552474

Review from a similar Derale Dyno-Cool in Transmission Coolers


Ive got a 1999 4runner that had the unfortunate luck of having the integrated transmission cooler line rupture inside my radiator. needless to say, the transmission didnt agree very well with having engine coolant running through it and finally died out on me. I bought this transmission cooler to isolate the transmission and the engine cooling systems. The cooler arrived a day ahead of schedule, which is always a bonus. I didnt rate it at 5 stars because I havent had a chance to install it yet and see how it performs, but judging by the reviews that I have read so far, the customer service provided and the prompt delivery, I would say that this transmission cooler will keep my truck running for a good long while. Everything pictured arrived in the box and I have no doubt that it will perform as expected. I will definitely recommend this product and this company to my friends! 30988

Review from a similar Derale Dyno-Cool in Transmission Coolers


Very easy install, absolutely no leaks anywhere in the system after putting it into service. I did have to get additional hose for the install due to the location I chose for the cooler (personal preference). I centered it on the bumper side of the radiator to provide the best air flow. Remember to get a quart of transmission fluid to accomodate the larger system volume after the install. I took my grill off to provide the most room for putting the cooler in rather than trying to wedge it between the radiator and grill, made install the nylon fasteners through the radiator and cooler much easier. Should last for many years. 61081

I mounted this fan in the puller position on my auxiliary transmission cooler so that I can tow a 15ft travel trailer with my minivan. Installation was sweet. There was an instruction page in the box and enough parts for mounting. I was surprised at how much air this thing moves. I wouldn't call it noisy since the fan spins smoothly and quietly when I tested it out in the open, but when mounted in the congested grill area of my 2012 Dodge Grand Caravan I can definitely hear it hum more than the stock radiator fan. It pushes that much air. I would definitely recommend this product. 413989

Hi I need to know at what temp. is exactly activated Thanks

-- comment by: LIVIU - 08/09/2013

This fan does not include a thermostat system. It can be wired into the original electrical system and will then operate according to the thermostat system in the vehicle. It can also be wired to an on/off switch but that is usually only done if off-road and race applications. We have plenty of thermostat options, sold separately, for determining the temperature at which the fan kicks on. For example, part D16735 kicks on at 180 degrees and shuts off at 165 degrees. Part D16759 is an adjustable thermostat system. Turn-on temperate can be set any where between 150 and 240 degrees. The turn-off temperature will always be 10 degrees less than the turn-on temperature.

I ordered this cooler for my daughter's 2012 Nissan Rogue to fix CVT transmission heating up causing it to into limp mode. When I got ready to install, I found there was no place to connect the hoses to the transmission. The vehicle only had the direct "bee hive" cooler. Install was delayed while waiting to get a "4 tube bee hive" from a different supplier for an additional $114. 551625

I bought this cooler for my 2007 Chevy avalanche LTZ 4X4 with 5.3 motor. I also bought the adapter the adapter D13035 for my truck as well. It was a quick and easy install. I just got it installed on 2/2/2018 and took the truck for a drive and it has dropped my transmission temp at least 40 degrees. It took me around 40 min to install. Very Happy with this new addition to my truck. FYI if you buy this unit to make it easier i would order an extra Line because the one line will be cutting close to reaching location. 472461

good product form a great company ! my 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. 189096

After one of use on a 2005 Honda Pilot, everything is holding up just fine. The one star less is because of the difficulty in installing it on this particular vehicle. Although this is a universal component, it is MUCH easier to install on pickup trucks. Best of luck with a brand new rubber hose going on with any sort of ease. 521316

Our installers typically use some transmission fluid to make installing the rubber hose on the Insta-dapt fitting easier.

It appears that my transmission temp dropped about 40-60° adding this cooler. The hose was pretty hard to attach to the cooler, even with lubrication. The hose was also to small for my vehicle so I had to source other parts to make it work. I installed it on a 2017 explorer. 661750

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. 656607

Review from a similar Derale Dyno-Cool in Transmission Coolers


I just installed this on my chevy avalanche. Flipped 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. 591245

Review from a similar Derale Dyno-Cool in Transmission Coolers


Very good product works well. The reason for 3 stars, it's NOT a direct fit as described when I purchased the product. The transmission lines are fitted to the A/C condenser so they had to be cut and needed to buy a flaring tool to flare the cut transmission lines. I look at the product online and now there's a note stating altering OEM lines may be needed. This wasn't there when I purchased it which delayed my install for another day. 336579

The trans cooler was easy to install. I had to go and buy some more hose and mounting screws to make it work but I knew that before I started. The hose was because of where I wanted it mounted. The trans cooler is keeping the transmission about 30 to 40 deg cooler then before. 283694

  • Most Efficient Transmission Cooler Recommendation
  • Derale does not rate their transmission coolers in bTu but if you wanted a cooler that would work very well the Derale Stacked plate cooler # D54012 will be your best option. This is a stacked plate cooler which is the most efficient style by a long shot and is the biggest size we have at 13" Wide x 13-15/16" tall x 2" deep. While this may not be rated in bTu it would easily fit your 29,500 requirement.

  • Installing a Transmission Cooler in a 2005 Chevy Tahoe with 5.3 Liter Engine
  • All vehicles with an automatic transmission have a factory installed transmission cooler. It is usually located inside the radiator out of sight. The exception seems to be on some CVT transmissions or on certain vehicles where all the lines are hidden. There are lines going to and from the transmission for the fluid. A line goes from the transmission to the radiator and then back out to the transmission. When installing a supplemental cooler the flow will go from the transmission to...

  • Recommended Transmission Coolers for a 2001 Ford F-250 Super Duty 7.3 Liter V-8
  • Transmission coolers are not vehicle specific, but there are some that are recommended for your 2001 Ford F-250. The Derale, # D13502 is one of them. Basically, regardless of a super cool feature, you will need to choose a transmission cooler based on where you can mount it. The most efficient place is between the grille and AC condenser core(position A on the picture to the right). The second most efficient place is between the condenser and radiator(position B). In this position, it...

You will need to measure in the engine compartment of your 2008 Dodge Durango to make sure a cooler will fit. The most efficient mounting point is between the grille and AC condenser core. The next most efficient place is between the AC condenser core and the radiator (25 percent...

  • You can certainly use the Derale 24 Inch Frame Rail Fluid Cooler, # D13225, for your 1999 Ford F-250. You would also need Derale Radiator Adapter Fittings, # D13025, for the 7.3 liter Powerstroke. Any transmission cooler will could essentially be considered a remote mount application.

  • Towing Capacity of 2015 Chevy Silverado 1500 Crew Cab 4x4 with 5.3-liter V8 Engine
  • The best place to confirm the towing capacity of your 2015 Chevy Silverado 1500 Crew Cab 4x4 with 5.3-liter V8 engine is the printed owner's manual. This will reflect the capacity of your specific pickup with the particular mix of equipment installed on it at the factory, including the 3.42 differential. I reviewed the online trailering guide on the Chevrolet website and at most a properly-equipped 1500 can tow 12,000-lbs. But your 5.3L V8 crew cab 4x4 with 3.42 differential is shown...

  • Installing Derale Transmission Cooler, # D12904, on a 2008 Honda Pilot
  • To install the Derale Transmission Cooler, # D12904, on your 2008 Honda Pilot, you would take the long fasteners provided to mount the cooler. The most efficient place to mount the cooler is between the grille and the AC condenser. The included fasteners look like wire ties and go through the cooler and the component it is mounted to. On the other side, you will place a spacer and then the button lock to hold it in place. The last part of installation is to make the connections with...

  • Is Derale Series 8000 Transmission Cooler D13502 a Good fit for 2008 Honda Pilot?
  • Since transmission coolers are universal fit items, the Transmission Cooler, part D13502, will fit your 2008 Honda Pilot. Transmission coolers are very easy to install. It is mainly a question of reconnecting hoses and tightening clamps, and making sure you have room to mount them. We do have larger transmission coolers than the D13502, and you would simply need to measure to make sure they fit under the hood.

  • Transmission Cooler Recommendation for a 2003 GMC Sierra 4x4 1500
  • I can tell you that the Derale Transmission Cooler Pan, # D14204, fits most 1982-1999 model 4L60Es transmissions. Some models may require a smaller transmission filter to get it to fit. It will not fit on all models. The overall depth of the pan is 3-5/8 inches and the distance to the the 5/8 inch diameter cooling tubes is 2-1/2 inches from the top of the pan. The exhaust has been determined to be a possible hindrance of installing this pan on models newer than 1999. If there were no...

  • Where is the Best Place to Mount a Transmission Cooler on a 1967 Ford Galaxie
  • The best place to mount an automatic transmission cooler such as # D12904 on your 1967 Ford Galaxie or any vehicle is in between the vehicle grille and the AC condenser core. Here it will get the most airflow and be the most efficient. The second best place is between the AC condenser core and the radiator. And third, between the radiator and fan. I have included a picture that should also help along with a link to our help article on transmission coolers.

  • Differences between the Derale Series 8000 Transmission Cooler and the Dyno-Cool Transmission Cooler
  • The main difference between the Derale Series 8000 Transmission Cooler, # D13504, and the Derale Dyno-Cool Transmission Cooler, # D12904, is the construction. The Dyno-Cool cooler is a Tube-Fin style cooler has aluminum fins surrounding the tubes. The aluminum fins dissipate the heat from the transmission fluid in the tubes. The Series 8000 cooler is a Plate-Fin cooler. Plate-fin coolers are similar to tube-fin coolers, but they are more efficient. On these coolers the fluid is forced...

  • Transmission Cooler for 1998 Chevrolet C/K 1500 Pickup Towing 7000-lb Trailer Load
  • The good news is that since transmission coolers are not vehicle-specific you are free to install as large a cooler as you have the room to install it. Coolers come in several class ratings depending on their cooling action; I suggest a Class IV cooler like the 11 x 12-inch Derale # 13504 you referenced or the larger 15 x 10 Derale # D12904. For either one you will use hose fitting kit # D13035. Two linked articles will give you lots of good background on transmission coolers and I've...

The # D12901 cooler measures 13 inches wide, 5 inches tall, and is 3/4 inches thick. You will need to measure to see if you will have room on your snowmobile to mount the cooler.

  • Do the Fittings in Transmission Cooler # D12904 Require Thread Sealed Tape/Sealant When Installed
  • Adding thread sealed tape to the fittings in the Derale Transmission Cooler, # D12904, is not necessary, but you can use some as long as it is only on the threads and not on the face of the fitting. You do not want particles getting into the transmission, so you will have to be very careful. Since it is not necessary, I recommend just using the fittings by themselves unless you discover a leak after installation. Then it would be a good idea to add the tape. I do not recommend using...
