Tranny side had no problems. Oil side kept leaking and was eventually disconnected. Hose clamps for hoses need to be replaced with sealed units.

The kit is excellent, with a great price. I haven’t installed it yet. The kit doesn’t include the reducer for the smaller hose. Fast shipping and great support. Detailed Instructions would be extrodinarilly helpful.

The customer service is excellent thanks for the product. It is exactly as on the web site. Installing it on my truck. Honest, honorable people. I will continue to do business with. Thanks again

Package was delivered on time. Installed it the next day. Didn't realise it's for oil and transmition. Just needed the oil cooler. Either way it's installed. Took a bit as I mounted in a different location than in front of radiator. Only did the oil. Already have a trany cooler. However I might loop into the other side for a trany and use the whole radiator. So far so good

I have not had a chance to install this unit yet. From the looks of it though it is worth it. Install should be a breeze too. I purchased this for a 05 Dodge Caravan. It cam with all the different oil filter adapters color coded for the filter you use.

Without a video for my 2014 explorer and with limited written instructions I chose to find a repair shop that would do the installation. It cost me $360 to have the dual cooler installed. Most places won't consider third party parts to install and others that wanted to charge from $600 - $800 to install. Removing the front cowling, bumper, & headlights proved to be too big of a challenge without adequate instructions. Also following the installation I drove cross country pulling a trailer and I didn't trust my self with the work, and at near 70 years I no longer want to tackle such a job. Other than above I made it to California with out incident.
PS, it would have been helpful for an estimate of the additional engine oil and transmission fluid it would take to fill the new system.

This is a good product and installation was fairly straight forward. The directions do not address the transmission connection to the cooler. If it did, someone would have realized a part was missing from the kit. If you are installing this cooler on a Dodge you will need a different connector than the one provided. Dodge uses a snap in, rather than screw in, connector for the transmission line. I only discovered this by watching a video online which actually gives the Derale part number for the connector (I don't remember what it is). I explained this to the customer service agent and he did not believe me nor would he send me one for free. Since I ordered this kit specifically for a Ram I feel this adaptor should have been included in the kit. Disappointed about that, otherwise it seems like a good kit. I haven't tested it yet since I am waiting for the adaptor.

I installed the etrailer derale transmission cooler on my 2012 Toyota Tacoma. Hauled home a 3500lb tractor 3000 miles up hilly terrain and had no problems at all. Works great.
by: Karyn Ellis06/25/2016
I haven't had the transmission cooler installed yet but the service I received in ordering and the shipping was way above what I ever expected. Very friendly customer reps and they know their job.
by: Dave H04/03/2016
Easily installed to an 05 town and country. I think the 3/8 compression/ barbed fittings should be included in the kit though. Also do yourself a favor and make sure you get the hoses on the cooler before you tie it in place cause they go on HARD. Otherwise pretty simple. Installing for towing purposes. Took about 1 hour complete.
by: Leslie L08/24/2018
This cooler does a good job keeping transmission oil engine oil cooler.

- Solution For 2008 GMC Sierra 1500 5.3L Overheating When Towing 4,000 lb Trailer Up a GradeIf you are pulling a trailer under the towing capacities of your 2008 GMC Sierra 1500, the engine temperature of the truck should not overheat. I would recommend having the vehicle looked over by your GMC dealership. What I would recommend is adding a combination transmission and oil cooler, as well as a cooling fan. This will cool the transmission fluid, the engine oil, and engine. For this, I would recommend the Derale Combination Transmission and Engine Oil Cooler, part # D15903. You...
view full answer... - How to Increase Towing Performance with a 2006 GMC Sierra 3500In order to determine the maximum gross trailer weight (GTW) that you can haul with your 2006 GMC Sierra 3500, you will need to find both the gross combined weight rating (GCWR) and the gross vehicle weight (GVW). If you subtract the GVW from the GCWR that will give you the maximum GTW you can safely tow. These figures can be found on the white tag inside your driver's door jamb. Unfortunately, the towing capacity of your truck will not change even with the addition of performance enhancements....
view full answer... - Combination Oil Transmission Cooler Recommendation for 1991 Chevy K1500 5.7LThe Derale Combination Transmission and Engine Oil Cooler # D15903 would be a great choice for you except it does not come with the correct filter thread size. You need M18-1.5 mm and this comes with 13/16"-16. So instead you would want the # D15902 which does include this size for the threads. The sandwich adapter has a thermostatic bypass that will allow the engine to reach operating temperature before it starts to cool the oil.

I have attached a drawing that shows the best location for mounting a cooler, if room allows.

This is a plate-fin cooler which is very efficient, and will help improve your transmission overall performance. I have...

This unit measures 17-inches wide x 12-1/2-inches tall x 3/4-inches deep.

These extra component parts are the reason for the higher cost. For your Yukon you will use # D15903 along with Snap-In Radiator Adapter # D13035. I...
view full answer... - Cooler Options to Prepare 2011 Buick Enclave CXL for Trailer TowingAccording to the online information I found for your 2011 Buick Enclave CXL with front-wheel-drive, the vehicle is rated for a maximum trailer weight of 2000-lbs unless it is equipped with the trailer towing package, in which case its towing capacity increases to 4500-lbs. Both of the 2-inch hitches we offer for your Enclave have a 5000-lb towing capacity but since the vehicle is rated lower, that lower vehicle towing capacity becomes your actual working limit. The hitch I recommend is...
view full answer... - Will Derale Combo Transmission and Engine Oil Cooler # D15903 Fit 2005 Chevy Silverado LT 5.3L V8In normal conditions I think that the Derale Combination Transmission and Engine Oil Cooler, # D15903, would work fine for your 2005 Chevrolet Silverado, but since you mention the Mojave Desert, this is going to be a different story. With excessive desert temperatures, it is going to take quite a bit more to cool the transmission fluid and engine oil. In this case I would use 2 separate coolers and go with the largest ones possible. Of course you will want to take a measurement to see...
view full answer... - Is 210 Degrees for Transmission Fluid and 235 Degrees for Engine Oil Too High While TowingIf the transmission fluid temperature gets over 200 degrees Fahrenheit then you are reducing the life of the transmission so yes, I do recommend adding an additional larger transmission cooler. In regards to engine oil temperature, 235 degrees Fahrenheit is pretty normal, maybe a tad high. The Derale Combination Transmission and Engine Oil Cooler part # D15903 for GM or part # D15902 for all others would be a great addition helping with both engine oil and transmission fluid.
view full answer... - Engine Oil and Transmission Fluid Cooler Recommendation for 2005 Chevy Express VanBest solution would be a combination engine oil and transmission fluid cooler for your 2005 Chevy Express Van like the Derale kit part # D15903. This comes with all the fittings, lines and brackets needed to install in your vehicle. The oil filter fitting is a match for what your van has as well since it's designed for GM applications.

This combination cooler does have the proper thread type for the oil filter on a GMC truck. But for the transmission cooler part I recommend adding fitting # D13035 so you will not have to cut and flare any transmission lines. With these items you will not need anything else for the installation. I have...
view full answer... - Best Engine Oil and Transmission Cooler for a 2009 Chevrolet Tahoe with the 5.3L V8 EngineThe Derale Combination Transmission and Engine Oil Cooler for GM Applications part # D15903 does not have a class rating. The class ratings are a guide that we use to help consumers pick the correct transmission cooler for their towing setup. They are not used by the manufacturer but I would say the above cooler is a class IV which will be more than suitable for your 2009 Chevrolet Tahoe with the 5.3L V8 engine. In regards to installation, you will need to use the included plastic rods,...

Either way oil cooler kit # D15405 has both and will fit. It also comes with the proper filter thread size which will be 13/16-16, 18 mm x 1.5 mm, or 22 mm x 1.5 mm. Going with a combination cooler for oil and transmission fluid is not a bad idea. You could use # D15903 for GM applications or # D15902 which has multiple thread sizes. If more cooling is needed for each system you would want to...
view full answer... - Will Derale Combination Transmission and Engine Oil Cooler for GM Vehicles fit my 2006 GMC SavanaTransmission and oil coolers are universal items, save for the fittings. The Derale Combination cooler may work on your van, but you will have to measure the space available in front of your radiator. This dual cooler measures 17 inches wide, 12-1/2 inches tall and 3/4 of an inch deep. If there is enough space for this cooler to fit in front of your radiator then it will work with your vehicle.

Your owners manual suggests not using ACC at all during towing. It also states that you should follow the gauges which may be more sensitive to heat when towing to remain safe. It could be that your thermostat is misreading, but it is very likely you need to add a cooling system which is normally included with a towing package. Adding coolers will only help your vehicle...

This is a great tube-fin cooler that will keep both the engine and transmission cooler with one compact system. The unit measures 17 inches wide, 12-1/2 inches tall, and 3/4 inch deep, so you will just want to make sure you have enough room between the grille and AC condenser on your truck for it to install.
