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.

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!

Have I gotten my refund for trans cooler fittings that weren't needed? 1994 k1500 trans cooler is working great.
by: Clinton05/18/2022
Very handy for unique installations fo transmission coolers
by: Tim Hansen08/29/2011
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.

- Can the Auxiliary Transmission Cooler be Bypassed on a 2002 GMC Sierra 1500 Z71Yes, you can bypass the auxiliary transmission cooler on your 2002 GMC Sierra 1500 Z71 but you will need an adapter to do so, the Derale Radiator Adapter Fittings for GM part # D13018 which goes straight on the radiator and allows you to hook up the new lines without any splicing. We typically recommend you just install the new one in-line with the old one. However, if you choose not to then I recommend using a cooler with sufficient capacity such as the Derale Series 8000 Plate-Fin Transmission...

There really is not set amount of time because every vehicle is different and different size engines have more or less space and use different fittings. For a 2003 Jeep Cherokee with a 4.7 liter, use Derale Radiator Adapter Fittings, # D13018. For a 4.0 liter, use kit # D13028 for 3/8 inch x 3/8 inch hose splicers, or kit # HH41413. On a 2003 Jeep Grand...
view full answer... - Transmission Cooler to Correct Transmission Overheating Problems in 2002 Chevy Silverado 1500 6.0 V8The best option for your 2002 Chevy Silverado with the 6.0L V8 engine is a plate fin cooler like the Derale # D13504. The plate fin style cooler helps dissipate heat better than a tube fin style and this is the largest cooler that is going to fit in your vehicle. These are relatively easy to install and will help cool down the transmission by using the air intake from the front of the truck. You will need to add the Derale Radiator Adapter Fitting # D13018 for this to be compatible with...

Part # D13018 comes with a quantity of 2 which you will need to install a transmission cooler on your vehicle.

view full answer... - Recommended Transmission Cooler For 2007 Chevrolet 3500 Express VanThe transmission cooler I recommend for your 2007 Chevrolet Express is the Derale Series 8000 Plate-Fin Transmission Cooler, part # D13503. This is a Class lll cooler and will work great with your Express. You will also need the radiator adapter fittings, part # D13018. The first thing you would need to consider is the size of the cooler. Generally, the bigger the cooler the better. The next thing to check out is the mounting location. I have attached a drawing of the best mounting locations...
view full answer... - Transmission Cooler Recommendation for a 2014 GMC Sierra 1500For 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.
view full answer... - How Many Adapters Is Needed to Install Transmission Cooler in 1997 Chevy K1500The Derale cooler part # D13503 is a great choice for your 1997 Chevy K1500. You would only need one of the part # D13018 fitting adapter as it comes with two sides. One to use on the radiator to get the line to the transmission cooler and then the other one to attach back to the disconnected transmission cooler line that was removed. If oil filter clearance is already pretty tight I wouldn't recommend an oil cooler as they take up a bit of space that it sounds like you don't have. Is...

view full answer... - Will the Transmission Cooling Pan D14204 Fit on a 2000 GMC 4x4 1500 Sierra PickupI believe you are correct, the Derale Transmission Pan Cooler, # D14204, is designed for GM vehicles with 700R4 and 4L60E transmissions from 1982 to 1999 and we do not list an transmission cooler pan for the 2000 GMC Sierra 1500 with 4L60 M-30 transmission. I believe the issue you will run into is that the exhaust on the vehicle, or other parts, will interfere with installation of the pan to the transmission. The pan will fit the transmission if there are no parts on the vehicle in the...
view full answer... - Transmission Cooler Recommendation for a 2006 Chevy SilveradoI would recommend installing a supplemental transmission cooler on your 2006 Chevy Silverado. Your current setup MIGHT be adequate, but the number one killer of transmissions is excessive heat. So basically the cooler you can keep your transmission the longer it will last. The Derale Transmission Cooler # D13504 that you referenced would be an excellent choice for a transmission cooler. To make installation easier you may also be interested in the Derale Radiator Adapter Fitting # D13018. I...
view full answer... - Transmission Cooler Recommendation for a 2003 GMC Yukon XL 2500 6.0 LiterAdding a supplemental cooler is a good idea, but you do not have to replace the factory one unless there is something wrong with it. You can add an additional cooler to work with the factory cooler for the optimum amount of cooling. When looking at transmission coolers I recommend going with the largest one that will fit in the available space in the engine compartment. There are 3 main locations a cooler can go: the most efficient is in front of the air conditioner condenser core/directly...

The part # D13504 would be an excellent choice for your 1998 Chevy Silverado 5.7 liter. I attached an install video that shows it being installed in a similar larger GM SUV.

This transmission cooler features a plate-fin technology which is one of the most efficient types of transmission coolers. The larger surface area (132 c.i.) will do an excellent job of keep the transmission fluid cool while towing your camper.

Typically what is used is a line that runs from the transmission to the radiator. The radiator holds engine coolant and the transmission fluid line is run inside the radiator as well. The radiator cools both the engine coolant and the transmission fluid...
