2008 Jeep Grand Cherokee - Derale Dyno-Cool Tube-Fin Transmission Cooler Kit - Class II - Economy
- Tube-Fin Cooler
- With 11/32 Inch Hose Barb Inlets
- Standard Mount
- 13W x 7-1/2T x 3/4D Inch
- Derale
13" Wide x 7-1/2" tall x 3/4" deep, reliable, all-aluminum tube-and-fin cooler extends the life and improves overall functioning of your Jeep Grand Cherokee'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 small to mid-size trucks and SUVs
- Imported
Specs:
- Inlets: 11/32" hose barb
- Overall dimensions: 13" wide x 7-1/2" tall x 3/4" deep
- Core width: 10-1/8"
- Distance between inlets: 6-1/4"
- 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.

Wanted to give my Honda better ability to handle a tow. this baby does the job. Transmission definitely cooler operation since the install. The install was simple and straight forward.

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.

2005 Honda Pilot
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.

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

Jeep Grand Cherokee
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.

1999 Toyota 4Runner
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!
by: Dave C12/10/2012
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.

2012 Nissan Rogue
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.
by: Barry08/14/2016
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.

2006 Chevrolet Colorado
for my 06 colorado with the 2.8l i4. also used the derale trans oil thermostat to help with warmup of trans fluid in winter. trans never gets above 190F now and the engine will overheat (212F) before the trans does. perfect upgrade for a light duty truck/van/car to provide a little bit of cooling at a compact size. very satisfied with the product

Ford Flex
We installed a tow package on our Ford Flex. The transmission cooler was challenging, but everything else went smoothly. The product works perfectly.
by: Rick09/19/2019
The part itself was easy to install and it does what it is designed to do. Only trouble with installation was with the vehicle, I had to remove part of the front cover on my 09' Avalanche to get to it. Also, I wish I had bought a black one to blend in with the rest of the radiator.
by: Carl Hu.09/15/2015
Nice inexpensive transmission cooler. Simple installation, although I didn't use the through radiator plastic ties supplied. Drops transmission temperatures well.

2008 Chevrolet Silverado
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.

Great product. Delivery was quick.

The transmission cooler, along with all the other products I ordered from etrailer was an excellent buy. they arrived on time and in excellent condition. The best benefit of ordering from etrailer is the superior customer service. I was even able to talk directly with one of their installers when I had a question.

- Transmission Cooler Recommendation for a 2005 Acura MDX Towing a 3,750 Pound Boat and TrailerThe 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...

The ideal place to mount a transmission cooler for maximum cooling efficiency is behind the grill of your 2011 Subaru Outback but in front of the radiator. You will want to measure at the front of your vehicle to make sure there is room to mount part # D12906 as it measures 13 inches wide and 7-1/2 inches tall. Another Transmission...

I would suggest getting the Class IV just to get the most cooling for the purchase. They all install relatively the same so I've included an installation video to help you do it on your own!

To install the cooler on your Taurus, you'll first need to ensure you have available space to accommodate the 12-3/4 x 7-5/8 x 3-3/4 inch size of the cooler/fan assembly. You'll need the # D15752 Install kit with thermostatic fan control for the oil cooler portion of the install and to tie in to the transmission return line, you'll need # D13014 if your car...

Using a weight distribution system really is a great idea but it would not have any affect on the performance of your engine. I have included an article which covers common weight distribution and sway control questions. When it comes to performance of your 4Runner, one recommendation...

So it would be in line from the fluid return line, this is the recommended way to install part # D12906. For mounting the unit, it is recommended that part # D12906 be mounted behind the grill and in front of the Air Conditioning Condenser Core, (see video link for reference). You can mount part # D12906, between the condenser core and the radiator but it will cut down on the cooling...

The coolers we carry are designed to supplement the factory cooler although some people have used them to replace the factory cooler. You would want to go with the largest cooler possible if you bypass the factory cooler and the inlet/outlets on the radiator for the factory cooler will have to be plugged. Or instead of the largest cooler you would...
view full answer... - How to Determine How Much Fluid Should be Added After Installing Transmission Cooler What you will want to do is check the transmission fluid level after installing the Derale part # D12906 and then add as much as needed. Most likely around a 1/2 qt would be needed but that will depend too on if you spill any fluid (most do) and how long of lines you use.

To remove the grille you will start by removing fasteners on the top of the trill underneath the hood. Once you have removed those fasteners and the top panel is loose then you will have 4 clips on the bottom to release to pull the grille straight out the front. Be careful not to pull up as that may break the tabs on the bottom of the grille that hold it in place. Once you have gained access you will be able to install a transmission...

Especially considering the mileage on your vehicle, the length of your trips with the trailer, and since your vehicle manufacturer recommends one.

Since the dry weight of the trailer is 4300 lbs more than likely you will be right at the towing capacity of the Mountaineer when the trailer is loaded. Because you are close to your towing capacity of the Mountaineer I definetly recommend a weight distribution system but the Curt Weight Distribution System with Shank - Pin-Style Trunnion...

To determine the correct fitting you will need to know the threaded diameter of the transmission fluid line fitting in your vehicles radiator. If you need a 3/8 inch fitting you would need a Derale Radiator Adapter Fitting Kit, part # D13014. If you need a 1/2 inch fitting I would recommend a Derale...

Cooler transmission oil gives more reliable, consistent shifts under racing conditions and prevents transmission damage under extreme towing conditions.

view full answer... - Transmission Cooler Recommendation for a 1996 Nissan Pathfinder Towing a 1900 lb TrailerThere really is not a down side to using a transmission cooler on a vehicle. It has been proven that transmission coolers will prolong the life of a transmission. Especially when the vehicle is towing a trailer. I would strongly recommend you install one since you will be pulling a 1,900 lb trailer with your 1995 Nissan Pathfinder. The power switch might enhance the shift points so that it will perform better while towing, but it will not prevent excess heat from building up in your transmission...

There will be 16 plastic rivets that will need to be removed. You can use a screwdriver to pop them out. Take your time getting these out so you do not break them.

view full answer... - Transmission Cooler Recommendation for a 2005 Nissan Pathfinder 4X4 SE and 6K TrailerFor a trailer weighing 6,000 pounds I recommend going with a stacked-plate cooler because they will be the most efficient and will provide the best cooling compared to the other cooler options. For a kit you can use # D13403. For the best cooling you can get a cooler that comes with its own fan like # D13950. This will provide the optimum cooling no matter where the unit is mounted.
