Best Chevrolet Silverado Transmission Coolers

Well constructed. Could use more hose for the install. I had to buy another length to install it. In the photo you can see I fabricated brackets for it so it would be able to get better airflow. Not noticing a real big difference in cooling but I’m anxious to see how it goes when I tow my 29 ft. TT with my 17 Suburban with a 5.3 ltr. I’ve been towing without one with no issues but any help in extending the life of the tranny is worth it.

Keeps my Tundra’s transmission tamed, especially while towing.

Works fine and wasn't difficult to install. I didn't take the bumper cover off. Worked from top and below. Fashioned an aluminum brace.

The Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class III - Efficient did not come with the correct radiator transmission fitting for my 2004 Toyota Tacoma doublecab Prerunner v6 automatic transmission truck. However, I was able to use the fitting provided as a "splice connector" between tubing sections. I did not have to cut or trim off any of the stock rubber tubing to make the splice connection, but I did choose to use a couple of line clamps to secure the tubing to the front frame crossmember. Because of existing AC condensor tubing, braces, and other items in the way, placement of the transmission cooler on my vehicle will ONLY fit in the upper passenger side of the radiator, in front of the AC condenser. It was extremely difficult to get the cooler into this position. Completely removing the entire front grille would have helped, but I chose NOT to because all of the 21 year old plastic clip grille fasteners would inevitably break and need replacement ($$$). I ended up accidentally bending some of cooler fins when trying to get it into position. Not sure if I can straighten out these bent cooler fins after the install but I am going to try. I also don't know how much additional transmission cooling I am now getting because I don't have a temperature gauge connected to my transmission. I simply have to trust the cooler is doing its job.

So far so good, easy install

Transmission cooler installation on 2012 GMC Yukon 5.3L. Top brace added for support.

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.

Great product, I’m currently in the middle of the installation.

I put the transmission cooler on a 2006 ram 2500 it keeps it 30° cooler than the OEM transmission cooler

Cooler was well built and fit my 2002 Silverado with some slight modifications to the existing bracing. It seems to cool well but I haven’t towed anything heavy yet in warmer temps to know how well it cools above the stock cooler.

Absolutely awesome!!!! Took 100 degrees out of the Trans! Pulling a trailer through the mountains. 100% recommended. It didn't fit quite perfect on my 2014 yukon and had to buy more hose but worth every penny spent! I will buy again

"02" F250 7.3 Super Duty I found the service from etrailer to be very satisfactory. The product arrived in good shape and on time. The on-line video was very helpful. Installing went smooth with one exception. As mentioned in many other on-line reviews, there was not enough hose supplied with the unit. While I had not problem with needing to purchase a small amount of hose, the package indicated that it was to be 5/16" ID. While the supplied hose was made in China and the walls of that hose where very flexible, the Gates hose, (made in the USA) was very rigid and would not go on the stud of the cooler, requiring a second trip to the Auto parts store to purchase 4' of 3/8" hose. A 12 mile round trip. Also, required the purchase of a knurled ended 5/16" hose connection and on qt. of tyranny fluid. Total added cost of $20.20. Have not towed with it installed yet.

This is my 1st after market trans cooler and i was always under the impressuon to get the biggest one that will fit. This is the biggest one without any modification. Easy install installed between a/c confessor and existing stock trans cooler bracket. I bypassed the engine radiator all together so I'm running 2 coolers the stock one and D13105. It's installed on a lifted with 35in tires 2012 silverado 6.2l 4x4 6l80 trans with the tow package. It's May 22 and 93 degrees the avg every day running temp before install was 193 now my running temp is 142, I ccouldn't believe how much of a difference the cooler made. I haven't tried it in 4x4 yet but I'm sure it's going to be just as good. This coming weekend is memorial day so I'm planning a weekend on the beach going to do some off road 4x4 and for sure pulling some stuck people out of the sand. If i can post and update of temps from the weekend I will .

I have been happy with the Derale transmission cooler. Installation was simple enough and one year later it is still working fine

i recived my Derale Series 9000 Plate-Fin Transmission Cooler Kit w/ NPT Inlets - Class I -Extra Efficient - D13611 and i really like it its well built and it look to be heavy duty and am looking forward to installing it.thanks again for a great item.

I had a continuous slight leak on my transmission pan that would not go away. I finally went shopping on line and found you sight while being impressed with the design of your product I ordered one from you. I received it in the mail very quickly and installed it. The installation was easy and everything matched my transmission. Filled the transmission with transmission fluid and after driving my motor home for a short while now have had no more leaks. Thank you for making a great product

Installed before retiring s from the Marine Corps, hauled just over 39,000lbs with my truck and she never came close to the red. Thank you for a great product and fantastic customer service.

My vehicle originally did not have a transmission cooler. After warming up, my transmission temperature would typically be 100 degrees higher than the ambient air temperature, whether moving or stopped. Towing the largest enclosed U-Haul trailer (6'x12') would raise the temperature to about 120 degrees above ambient. After adding this cooler, the transmission stays about 70 degrees higher than the ambient air temperature on the highway, and 80-85 degrees above ambient while parked or driving in slow traffic. I haven't towed that same U-Haul trailer since adding the cooler, but towing a much larger (8.5'x20') enclosed trailer raises the temperature to about 110 degrees above ambient. If you can find a spot the cooler will physically fit, it should work for your vehicle. You may have to get creative to solidly mount it. I used an angle grinder to remove part of a factory brace. When doing work in this area of your vehicle, be careful not to puncture the AC condenser! If you do, like I did, you will have to replace it. Some AutoZone locations will rent a vacuum pump and manifold gauge set. Doing your own repair means the total repair cost is only the sum of the new AC condenser and refrigerant. The inlet/outlet NPT fittings on this cooler need to be tighter than you think. I was worried about stripping the threads, and didn't tighten them enough at first. I ended up removing my bumper cover multiple times to tighten them until they stopped leaking. I found the best way to detect a leak was to zip-tie a folded paper towel below the fitting. If it turned red, there was a leak. For my application, I would have preferred built-in 3/8" hose barb inlets instead of the 1/2" NPT fittings.

Great quality! Simple installation, awesome product.

Seems very solid installed easily works well!

Easy to install and has worked great on my '06 4Runner v6. A little extra piece of mind for the mountains. This size just barely fits on the passenger side of the radiator - there is a central, vertical support bar behind the grill that prevents a wider cooler from fitting.

This cooler is absolutely the most efficient cooler money can buy for the tacoma. It fits the space without changing any wiring. You just relocate the horns to the center post. I pull a 5K travel trailer and this cooler lowered my transmission temp a solid 30 degrees. This is the best money you can spend on your 2005-2015 tacoma if you tow a trailer.

The oil cooler worked flawlessly. It brought down my transmission temp by at least 55* degrees. The construction of the oil cooler is like no other. Very well put together so glad I went with the stacked plate.

A quality product and great service. The D15900 should eliminating transmission overheating while stuck in traffic on Power Tour.

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!

I just installed this on my chevy avalanche. Flipped the bottom brace around in order to mount to. The hardest part is getting the hoses on the cooler and over the return line. I ended up getting a 90 deg quick connection coming from the radiator instead of using the one I got from etrailer. This keeps the hose from bending as much. Also purchase the installation kit with a hose as you will need an extra hose. After install I wish I would have went with the next bigger unit which is 10 high instead of 7 1/2 as I had plenty of room.

The fan is nice, the brass compression barbed fittings did not work. They leaked from both threads. I paid for fancy with a quickness 2 day shipping, took 5 days. I’m just glad I wasn’t too much in a hurry to cool my dads transmission for his road trip.

Everything was included to install the cooler and instruction sheet is useful. Hardest issue is where to mount. No leaks so far. Should help trans temps while towing.

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.

Excellent product, quality parts and fittings for multiple installation platforms. Took about 4 hours to install but was a custom install under bed of truck.
