Review from a similar Derale Series 8000 in Transmission Coolers


2009 GMC Yukon XL towing a 7,800lb travel trailer from California to South Carolina..... I don't believe the Yukon would have made this journey if it wasn't for the additional transmission cooler and engine oil cooler. Dragging the travel trailer through the mountains during the heat of the summer was taxing. However, my transmission never got above 190 F when it was over 100 F outside. Before installing the oil cooler AND transmission cooler, my engine temp would go to the 1-2 o'clock position and transmission temp would get up to 210 F. Highly recommend this product. 548155

I was lucky enough to have Etrailer install this on my Grand Caravan (they made a video). I drove 800 miles towing a 6x12 enclosed trailer with NO problems. It kept my transmission cool towing through the mountains. I have towed smaller trailers with the minivan that made it shift strange. After installation, all better. 17549

Review from a similar Derale Series 8000 in Transmission Coolers


Product was as described on the website. Installation took a few hours - no where near as easy as shown on the installation video - to install on my 2004 Alero. The challenge is that the upper line transmission cooler line is the line you have to route the cooler hoses to and mounting the cooler and getting the lines routed up to the top of the radiotr houseing required removal of the front bumper, loosening the radiator mount (from below the car - there are two wing nuts) and then CAREFULLY drilling a 11/2" hole in the plastic molding that completely covers the front upper portion of the radiator. Then you can route the hoses through the hole. I bought the optional GM fittings and that made connecting the hoses very easy. 17938

No good spot on 2016 explorer limited to mount this. None of the recommended spots were feasible for install. Could have mounted it to a composite cross member, but chose not to. Will be returning item. 678880

Review from a similar Derale Series 8000 in Transmission Coolers


Installed the product today. My installation is pretty unique on the Jeep Liberty CRD. This vehicle has a pusher fan in front of the stack of heat exchangers (Condenser/Trans cooler, intercooler, radiator), so the "zip tie" installation is not an option. Also, the stock trans cooler, which is the bottom 1/4 of the A/C condenser, has a different type of fitting on it. Product seems to work as intended. Hoses were a bit hard to get onto the barbs, even with a little transmission fluid as a lubricant. 47086

Review from a similar Derale Series 8000 in Transmission Coolers


Just installed this today on 2007 Honda Odyssey. JUST enough hose. Enough hose clamps if you reuse the factory ones on the trans connections. Did not need to take the bumper or bumper cover off, just the grill, and top and bottom covers. However, this makes it very difficult to get those zip rods attached. It was possible, but I had to get my tiny wife to fit her hands down there for the bottom ones. Now, lets see if it will save my tranny when I start towing 3500 lbs for 2 months and 4000 miles... will have to report back then and give a real rating then. 251259

I am submitting this review even though all of your customers MUST know you have one of the best, if not THE best, trailer company in the USA. You have the best products, the best selection for various applications, and no other company can beat your prices... I already purchased a lot of your products and believe me when I say I did extensive research on the exact same products before submitting my orders due to my limited funds. All of your staff are kind, courteous, patient (when it comes to helping a trailer-newbie, such as myself) understanding, very knowledgeable, and professional. Submitting an order is easy, and all of my various orders where shipped almost instantaneously and arrived on schedule. You are the best... and then, there are all the rest! Thank you for having such a great operation! 526514

Review from a similar Derale Series 8000 in Transmission Coolers


Fun to install but if you follow the video it goes really smoothly. This was the number 1 recommended cooler for my 2012 Honda Odyssey Touring so I went ahead and got it. Before installing it I hooked my scanner to my van and drove 2 straight hours in the city and on the high way, transmission fluid temperatures would reach 195 at times. After installing it I tested the temperatures under normal driving and under towing. Under normal driving, after 2 hours the transmission fluid never got over 170. It took almost 3 hours before the transmission fluid reached 185. The van was already nice and warm when I decided to test towing so I'm not sure how long it took to get up to temperature but I can say after 45 minutes of driving through the Saura Town mountains (Hanging Rock, NC), the transmission temperature never went above 190. I would give 5 stars but the provided hose was not the correct ID and I could not get it to fit properly so I had to go buy more hose. 444073

Review from a similar Derale Series 8000 in Transmission Coolers


We've had it for a year in our 2008 TrailBlazer 2WD with 4.2L inline 6 cylinder. I think it's about the largest that would fit and we got it for a towing our 21' expandable camping trailer that can be about 4,500 lbs. max. Works great, although I added another install kit to be sure I had enough hose and the extra brackets and connection adapters. I did not want to use the mounting parts that poke through the radiator and A/C condenser fins, so I got the Derale kit with brackets and hose in an affordable kit together, part # D13006. 520230

I didn't know how to select the right trans cooler for my towing needs and I probably would have figured out how to mount it but with the help I got from your web site, I knew I had the right cooler and I knew how to install it in my vehicle. I saw a video of a cooler just like mine installed in a truck exactly like mine. How cool is that? etrailer.com is now my only source for trailer and towing parts. 408106

Great quality add on, I have bought less expensive transmission coolers, but this one has OEM quality. Well built, it will most likely outlast the vehicle I am installing it on. 488096

Review from a similar Derale Series 8000 in Transmission Coolers


This transmission cooler fit perfectly behind my grill. I mounted it on brackets in lieu of a direct mount on the radiator. I’m glad you recommended the GM adaptor hose fitting as my application would not work with the Insta-Dapt which was not compatible. Works great towing my 4,000# trailer in this Florida heat. 524895

Review from a similar Derale Series 8000 in Transmission Coolers


I decided to install the Derale 8000 on my 2005 Honda Odyssey with 57,500 miles as an investment in hopes to prolong the life of vehicle. The Derale 8000 series came with complete with all the parts needed for my installation. I had zero trips to the auto parts store. I'm not a mechanic but the installation was fairly easy. The videos provided by etrailer was extremely helpful and gave me confidence to do the install. The hose, provided, fits perfectly into the factory Honda hose outlet from the radiator. Also, as mentioned by other reviewers, installing the hose is a difficult even with transmission fluid to lubricate. However, I had a hard time trying to secure the cooler, due to the tight space between the condenser and radiator. A long cutting pliers/scissor would help and a lots of patience. Install with confidence! Thanks Etrailer for the awesome instructional videos! 391814

Review from a similar Derale Series 8000 in Transmission Coolers


I ordered a transmission cooler for my '09 Tahoe that, even with the small cooler for the towing package, just could not handle the California/Oregon mountains. I had my trusted mechanic install it (he has much greater expertise than I). I've just returned from an identical trip over those same mountains. What a difference! Instead of topping out at 230 degrees (dangerous), I topped out at 183, only 13 degrees from normal operating temp. I ordered the cooler and installation hardware. It's been awesome not to have to worry anymore about transmission burn out hauling my trailer that is 25% BELOW advertised towing capacity of this vehicle. Kudos to etrailer for offering such great products! 302744

Excellent quality and build. I installed this in a 2003 Chevrolet Avalanche. I wanted a factory look installation so I mounted the bottom of the cooler in the factory bracket located mid way and made a bracket to mount the top of the cooler. I mounted it with the hoses downward so they will not be visible from the outside of the car. See pics for details on the brackets and mounting. 176500

Have a 1998 Lincoln Mark 8 w/ 4 speed automatic which retails for no less than $ 4000.00 - Having this potential monkey on my back , I decided to invest in a trans cooler. Fabricated mounts and bolted on , used double flare connection to cooling line w/ barbed fitting ; barbed fitting @ radiator fitting. Used 2 hose clamps @ cooler, one clamp on each barbed fitting . Could only mount with fittings to left ,fluid leaves radiator , enters cooler @ top ( to reduce pump load ), comes out of bottom & returns to tranny. No trans temp. guage, but cooler gets hot @ idle, verifying cooler works . Well constructed and sturdy,easy to mount ; comes with instructions. 296567

Review from a similar Derale Series 8000 in Transmission Coolers


Hello Gang, I have a 2013 Chevy suburban and tow a 7K plus travel trailer. While we were towing to Colorado near Cripple Creek the temps were low 90's and my trans spiked at 230. Had to pull over to let it cool down. Now keep in mind my suburban does not have a HD trans cooler just the stock radiator cooler. Fast forward one year now my stock trans line is starting to leak from the rubber hose so it's time to change. Decided to order the larger trans cooler might not have been the best idea as it's larger then where I wanted to put it. So after taking off the front bumper, headlights misc brackets and lots of bolts I was able to get it up behind the "A" frame bracket in front of the radiator. Make sure if you go this route to put the rubber hoses and clamps on before installing because you will not be able to install the hose after. The bracket the holds the hood latch has openings that just happen to line up with the inside bolt holes on the cooler. Hoses facing down You will need to cut the bottom of the plastic out of the way to route the hoses under the frame. Cutting the original trans cooler line was easy and the rubber hose was long enough to make both connections so I did not need the adapter. If I used the adapter the rubber hose would be too short. On the bottom I used the foam pads between the cooler and the frame and secured it with heavy duty Zip ties. Can't wait to test it out this summer. I forgot to take pictures of the final install but did take one picture showing the "A" frame in the middle of the radiator. It fit's perfectly behind it. 613917
