Have I gotten my refund for trans cooler fittings that weren't needed? 1994 k1500 trans cooler is working great.



by:

Piece of crap



by:

Very handy for unique installations fo transmission coolers



by:

It looks like from reading the matierl if one is using the cooler in series with the factory cooler this adapter is not needed.
Thus I would like to return, but I fear the shipping cost will not make sense, dollar wise...

Thus the recommendation should state if you are adding a cooler to your system where one does not already exist, then you'll need this adapter.

So if your adding to an already existing system, you do not need the adapter.



by:

Got those radiator fitting male an female for my 97 Chevrolet ,worked perfect d13018 made easy job out of hooking up my trans cooler ! A must have .just wish I had got my trans cooler from etrailer they are a great company .so if you gonna put a trans cooler own you GM truck take my word for it you best go to trailer! Won't be sorry, thanks



by:

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!



by:

So far the trans cooler has been working well. I also used the adapters. Both products are doing well after 1500 miles or so and many hills, mountains, and trailering.

  • What Cooler is Best for My 2002 Chevy Silverado 2500 6.0 Engine for Towing a 38' 5th Wheel?
    Hello Paul, Definitely a good idea to keep your transmission cooled while pulling a 38' 5th wheel. I found another option that I thought would fit your needs a little better, I went ahead and reached out to my contact at Derale and he agreed. The Derale Hyper-Cool Remote Transmission Cooler Kit w/ Fan, -8 AN Inlets - Class V # D15960 is going to be your best fit. You will still need the correct adapters, you will need to double check what kind of fittings your truck has. For your standard...

  • Transmission Cooler Recommendation for 2011 Chevy Silverado
    You are a little on the warm side for your transmission fluid. If you can keep it under 200 degrees you will have the max life out of it. That being said transmissions really start to go downhill at 260 degrees. The Derale cooler part # D13503 with the install fitting part # D13018 is the most popular option for your 2011 Chevy Silverado 1500 and would work well. I attached an install video that shows the cooler installed in a similar GM vehicle.

  • Recommended Transmission Fluid and Engine Oil Cooler for a 2013 Chevrolet Express Van 3500
    I have exactly what you will need to keep both the engine oil and transmission fluid cool in your 2013 Chevrolet Express Van 3500 but a remote cooler will not be necessary. Instead, I recommend using the Derale Combination Transmission and Engine Oil Cooler part # D15902. As long as you have at least 17" wide x 12-1/2" tall x 3/4" deep of space to mount the cooler behind your grille and in front of your radiator/condenser then it will work well for you. You can expect a drop in engine oil...

  • Best Transmission Cooler For 2002 Chevy Tahoe 5.3L LT With 4-Speed Transmission
    Hello Dale, thanks for reaching out. The best transmission cooler for your 2002 Chevy Tahoe 5.3L if the following: - Derale Dyno-Cool Tube-Fin Transmission Cooler Kit - Class IV - Economy # D12904 This is a 15-1/4" Wide x 10" tall x 3/4" deep Aluminum cooler. Keep in mind, the Derale Radiator Adapter Fitting # D13018 will be required only if your vehicle is equipped with 5/8" hex on trans lines.

  • Transmission Cooler Recommendations for a 1998 Chevrolet Silverado 4X4 5.7L
    To determine what kind of transmission cooler you will need depends on how much weight you will be towing and where you will be towing. Also, you will want to check how much room you have in front of the radiator to be able to install the transmission cooler. If you will be towing a light load, less than 2000lbs, in flat driving conditions, your 1998 Chevrolet Silverado 4x4 5.7L will do fine with a class I rated cooler. If you will be towing more than a 2000lb load through some hills,...

  • Best Transmission Cooler for a 2003 GMC Sierra 2500HD with 6.0L V8 Engine
    For your 2003 GMC Sierra 2500HD with the 6.0L V8 engine, I highly recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13504. This 8000 series cooler measures 11" wide x 12" tall x 7/8" deep which will be a good fit for your truck. You can expect temperature drops anywhere from 20-30 degrees fahrenheit while using this cooler which will dramatically increase the life of your transmission. Installation is very simple as you can see in the attached video but you will...

  • Will a 3/8 Hose Fit an 11/16 Inch Fitting to Install a Transmission Cooler on a 2006 GMC Sierra
    There is a lot of pressure within the transmission lines of a vehicle, including your 2006 GMC Sierra so the tighter the fit the better. If an 11/32 inch hose is needed then I would go with it over a 3/8. Cooler # D13503 isn't really large enough or efficient enough to allow you to bypass the factory cooler. That is why I recommend installing the cooler as a supplemental unit. If the fitting on your radiator has a 5/8" hex head then you can use special fitting # D13018 and not have to...

  • Can the Derale Stacked-Plate Transmission Cooler Kit Be Mounted in Any Direction or Orientation
    The inlet and outlet on transmission coolers can be oriented in any direction you like and because the cooler is a flow through device you can use either port as the inlet or outlet, whichever makes the installation easier and uses the least amount of hose. The one thing you want to be sure of, is that the cooler is mounted so that most air flows through it, usually in the same orientation as your radiator. The best installation location is as far forward as possible in front of the radiator,...

  • Recommended Transmission Cooler for a 2007 Cadillac Escalade
    The great news is that we do have transmission coolers to help you out. You will have to do some measuring in your engine though to see what will fit. Transmission coolers are universal fit so there is no "exact" fit for your 2007 Cadillac Escalade with a 6.2L V8 Engine. There is a little more into selecting the best transmission cooler than what the size of it is. I am attaching a helpful article that goes over the different kinds of coolers and what their advantages are. One of the...

  • Recommended Transmission Cooler for 2001 Chevy Silverado 2500 With 6.0L V8
    I took a look at the owner's manual for your 2001 Chevy Silverado 2500 and was unable to find any information concerning specific grades of hills and there isn't any type of specific formula that is used which has this information. The only thing mentioned in your owner's manual was that going up steep grades would cause overheating so I strongly recommend using an accessory transmission cooler. The best option is the Derale Series 8000 # D13504 because it is a plate-fin cooler that is...

  • Installing A Transmission Cooler On A 2007 Chevy Express 3500 6.0L Roadtrek Conversion Van
    To determine what kind of transmission cooler you will need depends on how much weight you will be towing and where you will be towing. Also, you will also want to measure the area in front of the AC condenser to see what size cooler will fit on your 2007 Chevy. I am sending a link to a FAQ page that will give you information on transmission coolers. The GTW rating is the Gross Towing Weight capacity. This is the weight of the trailer, including the load in the trailer. This will help...

  • Transmission Cooler Recommendation for a 2006 Chevy 2500HD 4L80E Transmission
    Good call trying to reduce your transmission fluid temperatures. The cooler the fluid is the longer the transmission will last. The best way to pick out the best cooler for a vehicle is to measure the area in front of the radiator/ac condenser and select the largest cooler to fit there. It also helps to get a stacked plate style cooler as they are the most efficient and pretty small in size. I attached a link to a page that has all of the stacked plate coolers we offer. I also attached...

  • Transmission Cooler Recommendation for a 2003 Chevy Silverado 2500HD
    You mentioned wanting the best cooler for your 2003 Chevy Silverado. The best, as in the most amount of cooling, is going to be a remote cooler with its own fan like # D13960. It does not matter where this cooler gets mounted because its fan offers the optimum amount of cooling all the time. Otherwise for a standard cooler that would require air flow I recommend # D13105. Its large surface area will provide plenty of cooling for your trucks transmission. To avoid cutting and flaring lines...

  • Best Solution for Lowering Vehicle Temperatures When Towing
    The added stress from trailer towing usually shows up as an increased transmission temperature. I am not sure if the gauge you're referring to is displaying engine coolant temperature or if you have one that shows transmission temperature. We do offer Derale Class III transmission cooler # D12903 for your 5.3L Yukon XL which measures a generous 15-1/4 x 7-1/2. This can be mounted in front of your AC condenser to provide supplemental transmission cooling after the OEM cooler in the radiator...

  • Can I Replace The Factory Transmission Cooler on a 2013 Chevrolet Silverado
    In regards to your 2013 Chevrolet Silverado, if you will be removing the auxiliary transmission cooler then I recommend using the Derale Series 9000 Plate-Fin Transmission Cooler Kit part # D13614 to replace it. This cooler measures 11" wide x 11-3/8" tall x 1-1/4" deep which you should have plenty of space for. In general we recommend that you install the supplemental transmission cooler in-line the factory transmission cooler (in radiator) and the auxiliary transmission cooler (behind...

  • Transmission Cooler Recommendation for a 2012 Chevy Traverse
    First, you do not necessarily have to remove the front clip on your 2012 Chevy Traverse to install a supplemental transmission cooler. It just makes installation a lot easier if there is nothing in the way. We have not yet installed a transmission cooler on a Traverse so I do not have a video or specific instructions on removing the front clip. When our installers perform an installation they have to determine where the fasteners are that hold on the front clip (if it is a vehicle they...

  • Recommended Transmission Cooler For A 1998 Chevrolet K1500
    I do have transmission cooler options available for your 1998 Chevrolet K1500 with 5.7L engine. As transmission coolers are universal, they will work in your vehicle with the provided space and adapter fittings. As a general rule of thumb, you will want to choose the largest transmission cooler for the space you have available between the radiator and grill of your vehicle. To replace or enhance your stock transmission cooler system, I recommend using the Derale Series 8000 Plate-Fin Transmission...

  • Recommended Transmission Cooler for a 1998 Chevy K2500
    For a transmission cooler that will work well for your 1998 Chevy K2500, I recommend using the Derale Series 7000 Tube-Fin Transmission Cooler Kit w/ Hose Barb Inlets part # D13105 as this is one of the largest, most efficient transmission coolers we offer for your vehicle. I recommend installing this transmission cooler in conjunction with the factory transmission cooler (if equipped). I also recommend placing the transmission cooler in front of your radiator behind the grill of the vehicle...

  • Transmission Cooler Recommendation for a 1998 Chevy K1500 Series Truck
    Factory transmission coolers are adequate at best at keeping the transmission fluid within the optimum 160 to 200 degrees F range. Adding a supplemental cooler is a good idea, especially since transmission fluid cannot be over cooled. If you do towing, hauling, or are otherwise looking to get the most life out of your transmission then adding a supplemental cooler would be a great idea. Cooler # D13504 is a good choice. To avoid having to cut and flare lines I recommend adding hose fitting...

  • Transmission Cooler Recommendation for a 2009 Yukon XL SLT 5.3 Towing an 8000 lb Camper
    When it comes to transmission coolers, I recommend choosing the largest transmission cooler that will fit into the available space. The ideal place to install a transmission cooler is directly behind the grill, in front of the radiator and A/C condenser. I would recommend measuring the available space so you know what size cooler to look at. For your 2009 GMC Yukon XL SLT with the 5.3 liter engine, I would recommend using the Derale Transmission Cooler, # D13504. This is a class IV cooler...

  • Transmission Cooler For 2003 Chevy Express 1500 For Towing
    The transmission cooler I recommend for your 2003 Chevy Express 1500 is the Derale Series 8000, which is the following part number: - Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13503 I like the # D13503 because of its efficiency; it is a plate-and-fin cooler, which means it uses smaller plates that cover more area than other coolers in order to agitate transmission fluid. Because you cannot over-cool fluids, the rule of thumb with transmission coolers is that size matters...

  • Location of Transmission Lines on a 2001 Ford Ranger For addition of a Transmission Cooler
    One of my co-workers here happens to have a 2001 Ford Ranger with 4.0 Liter engine and automatic transmission, so I went out and checked under the hood. The transmission lines are located at the drivers side radiator tank, see photo, and run down, then across to the passengers side before turning back and running to the transmission. You should check your vehicle because different vehicle accessories or packages and the engine size and drive train may affect the location of the transmission...

  • Transmission Cooler Recommendation for a 2014 GMC Sierra 1500
    For your 2014 GMC Sierra 1500 I would recommend the larger transmission cooler part # D13504 as basically the larger the cooler you have the better, and your truck would have room for it's size of 11" Wide x 12" tall x 7/8" deep. For a fitting that would allow you to install the cooler without having to cut or flare any lines you would want the part # D13018. Keeping the transmission fluid cool is the greatest way to prolong the life of the transmission as heat is a transmission's worst enemy.
