I pulled a tab 320 camper from WI to AZ with a RAV4 Toyota and back again!! Tranny cooler definitely made it a doable drive!! Thanks again !! 3511225

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. 242582

You only get a few feet of hose. I don't understand how you're supposed to hook into your transmission line with such small amount of hose. I had to purchase 9 ft from the logo auto parts store. That was only the beginning. The clamps are very cheap. Two of them broke while tightening them. I had to stop again and run to the hardware store for clamps. The whole ordeal was very frustrating. Do yourself a favor and skip the so-called kit. 3500322

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. 1025788

The cooler works great and fits good. I installed it on the bumper brace on our 2017 GMC Acadia. I dropped a star simply because it didn't come with the fitting the snap ring style line necessary to installing it on a newer GM vehicle. 3379004

This product is solidly designed and the installation kit well thought out. The connection hose was heavier and better quality than what the auto parts store could provide. I will be adding additional clamps to the connections so there are two on each just as a precaution against leakage. The single clamps are working well for my test period. I fabricated brackets for mine but using the plastic pins would work just as well. It is a huge improvement over the factory cooler. I would recommend it to anyone that is towing near or at truck capacity. 153950

This Transmission cooler really works well. It keeps my transmission much cooler while towing heavy trailers. I connected it in series with the factory coolers for a lower operating temperature. If towing or hauling heavy loads I recommend this plate cooler. Also plates remove more heat than tubes. 804231

I had this installed and after 1 month it started to leak from the fins. I ordered another, had it installed and it has worked with no problems. etrailer took the defective cooler back no problem and gave me a full refund. Excellent customer service 1502362

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.

Packaging was damaged but no damage to cooler due to solid construction. Had done online searches for installation tips and suggestions. All very beneficial. However, this cooler is larger than many I saw online and I had to find an alternate installation location. I was able to find a suitable location in front of radiator and minor modification (drilled two additional mounting holes in mount bracket and trimmed one corner for clearance.) Overall has shown lower transmission operating temps. Have not towed since installation and hope that lower temps carry over to towing a load. I give this product,shipping, and customer service a thumbs up. 644257

Kit had almost everything needed to install on my 09 Subaru Forester. The only extra thing I bought was another four foot length of hose.

I made brackets out of metal I had on hand for a more secure mounting, and I installed the cooler with the ports facing the drivers side. I wanted to avoid sharp bends in the hoses so I made loops in both hoses to connect to the existing lines in my car. I also slid pieces of old garden hose over the new hoses at points where it was close to metal parts to avoid chafing of the hoses. The hose supplied with the kit was the correct diameter for my car and the hoses slid onto the existing fittings.

I took my time with the install. I had to move the horn so I could position the cooler on the drivers side in front of the radiator and AC condenser. Routing of the hoses to the existing connections required some planning (and an extra hose) but everything else is very simple.

Very nice kit! 286681

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

The cooler was easy to install,the instruction were easy to follow. I did check the oil temp after pulling a 4000 ft grade pulling a camp trailer with an electronic temp probe and there was a 50 deg temp drop thru the cooler. 669243

and took about 2 hours from start to finish. Installation was simple and was able to mount on the A frame in front of the radiator. Installation instructions was clear and was helpful with determine the supply and return lines. Fittings matched up perfect with no need to change out. I had to purchase another 4' of hose but the cooler was a lot simpler to install than I had expected. 32710

The product is great, the only issue I had was that it did not have the correct connectors for the Jeep Wrangler, but I was able to get some quickly. It's kept my Jeep's Trans fluid temp nice and cool, even when pulling my 3k pound travel trailer.. GREAT! 1651335

Kind of an easy install on a 2011 Chevy Traverse LS. Fast shipping. Taking a long trip in a couple weeks towing a 3500 lb travel trailer. We'll see how it goes.
Thanks for all of the products etrailer has supplied to make my LS tow ready! 189591

The first cooler leaked within 1 month of installation but I returned it for a full refund, got another, and the second one has worked perfectly for the last year. etrailer has customer service second to none! 1588111

This oil cooler has really helped improve the oil pressure in my GEN III Hemi by reducing the oil temperate approximately 20 degrees cooler than before we installed it. Excellent product by Derale and service by etrailer.com. 1400952

Pretty easy to install. Worked great. Prior to adding this transmission cooler my transmission temps would routinely go over 200F so before I installed the cooler I had my transmission serviced. Thankfully no issues or burnt ATF. After installation the temps never went over 190F even towing in the south Louisiana heat. Great product and I'd buy again if needed. 1061956

This aux transmission kit was easy to install and did just the trick in bringing my engine and trans temps down form towing my trailer. Definitely recommend! 341347

Installed it on a 99 Ford F250 with a diesel, that was having transmission overheating problem when towing a trailer. Fixed the problem. 1126198

Works great to cool the air going into my Air Compressor tank. 1198833

worked well . 3429338

Parts arrived fast and in good condition. My setup needs recessed mounting, and I must use the cooler's bolt holes for proper clearence and support. Supplied plastic ties and foam are not quite enough for a secure mounting, and the supplied hose barb fittings are nice aluminum, but I need a 1/2" barb end, not 3/8". These little things are no problem. I'm happy and will buy from e-trailer again. 1091069

My original transmission cooler sprung a leak on my 1990 dodge pickup and a direct replacement couldn't be found. Etrailer had a cooler that would fit and do the job. Would highly recommend them to solve your problems and supply what's needed. 161616
