Very product thank you



by:

Have not installed them yet but it looks like this will make the job easier



by:

Great product! It makes the installation a breezy.



by:

I purchased these fittings thinking these would fit my GM product. NOT.......These are 3/8 and looks like the fit the truck series only as stated on the package. Be aware



by:

These fittings made connecting the hoses to the steel transmission lines very easy - glad I bought them! I recommend getting them.



by:

The adapter fitting did not fit my 2008 GMC Sierra 1500 w/ 5.3 liter engine and factory trailer package.



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:

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.

  • 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...

  • 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...

  • Recommended Transmission Coolers and Programmer For a 2001 Chevrolet Silverado 1500HD 6.0L 4L80E
    First I recommend getting a Edge Gas Evolution CTS3 Performance Tuner # EP39YR for your 2021 Chevrolet Silverado 1500HD. This will allow you to get more power to make towing easier on your Silverado and will also allow you to more accurately monitor temperatures on your engine and transmission. For your transmission I recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13504. This is a large plate cooler which will help to lower transmission temperatures when towing....

  • Transmission Cooler for Towing 5300 lb Trailer in the Mountains for 2007 Chevy Silverado 5.3L
    Since you will be towing in the mountains, which is hard on a transmission, I would recommend getting the largest, highest rated transmission cooler that will fit your vehicle. You cannot over cool a transmission. The ideal install location would be in front of the radiator and A/C condenser, right behind the grille. The # D13102 you mentioned will provide some cooling, but due to the fact that you will be towing up and down mountains, it would be too small for your needs. The largest...

  • 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...

  • How are the Derale Adapter Fittings # D13018 Installed and Used to Install a Transmission Cooler
    The male end of the Derale Radiator Adapter part # D13018 that you referenced does thread into the outlet side of the factory cooler in your radiator. The female side of this adapter would thread onto the male side of the coolant line that you removed from the factory cooler. I realize that's probably hard to visualize so I attached a diagram that shows how both sides of the adapter are used. I also attached an FAQ article on transmission coolers, plus a video of one being installed....

    It looks like for a 1996 GMC Yukon with 4-wheel drive and the 5.7 liter motor you will need fittings # D13018 to install the transmission cooler without having to cut and flare any lines. I have linked a video showing installation of a cooler you can use as a guide.

  • Fitting Adapter Needed to Install Remote Derale Transmission Cooler in 2004 Chevy Silverado
    The correct fitting for installing a Derale transmission cooler in your 2004 Chevy Silverado is the part # D13018 to install the Derale Hyper-Cool Remote Transmission Cooler # D13960. This cooler has a thermostat as well. You would want to route this from your current radiator's transmission cooler so that it goes through the factory cooler and then finally to this cooler. That is what the fitting allows you to easily do.

  • Transmission Cooler Recommendation for a 2012 Chevy Silverado 2500 HD
    Transmission coolers are not vehicle specific so you can install any one that will fit including # D13504. For the 6.0 liter engine you may need fitting # D13035. If you have a hard metal line and do not want to use the fitting, you could cut the metal line, flare it, and use hose clamps. The transmission cooler comes with hose, clamps, and mounting hardware. It also includes an Insta-dapt radiator adapter. This adapter is if you have a rubber line, not a metal line, so you can use the...

    We do offer Derale transmission coolers for the 2007 Chevrolet Silverado New Body with the 4.3L engine. These are shown on the linked page. For an efficient Class III transmission cooler you can use Derale # D13503 which you will install using the required hose fitting kit # D13018. These install directly into your radiator so you'll not need to cut or flare any fluid lines. Please refer to the linked video to see how this cooler installs. Two helpful articles are also linked for your...

  • Should 2007 GMC Sierra Classic be Put in 4WD When Towing a Heavy Load Long Distance
    I checked out the online version of the owner's manual and it looks like for your 2007 GMC Sierra Classic then you want to use the Tow/Haul mode for heavy towing and/or shift the transmission to 3rd or lower if it is shifting too often. Aside from that though it doesn't state anything about 4WD so I wouldn't worry about it. You may consider adding a transmission cooler like the Derale # D13502 to help keep your transmission from overheating and making your engine work harder. If you have...

  • Recommended Transmission Cooler for 2001 GMC 2500 HD Currently Running Over 250 Degrees
    For your 2001 GMC 2500 HD Sierra, I recommend the Derale Radiator Adapter Fittings for GM # D13018 along with the Derale 16-Pass Electra-Cool Remote Transmission Cooler Kit w/ Fan, 8 AN Inlets - Class V # D15900. This unit can be mounted anywhere you have space and has an in-line thermostat to shut off at 180 degrees to conserve energy. This will be a high efficiency cooler that can be mounted anywhere.

    Yes, you can run this Derale Series 8000 Plate-Fin Transmission Cooler Kit, part # D13502, in series with the factory transmission cooler that is on your 2002 Chevy 2500HD. A lot of people do this and it should help bring your transmission fluid temperatures down. You will want to route the transmission fluid through the factory cooler first, and then through the # D13502, and finally back to your transmission. Routing the coolers in that order is crucial, if you were to run the # D13502...

    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.

  • Correct Transmission Line Fittings to Install Transmission Cooler on 2009 Chevy Traverse
    According to Derale, the correct fitting to install the D13504 cooler in your 2009 Traverse would be part # D13035, if the return transmission line is attached to the radiator using an E-clip. You would need two of them. If the connection does not use an E-clip, you would need to use a compression fitting. The correct fitting will depend on the outside diameter of your transmission lines. For a 5/16 inch line use part # D13031, for a 3/8 inch line use # D13032 and for 1/2 inch line use...

With such a large cooler you may have to find a different location other then behind the front grille.
