13" Wide x 7-1/2" tall x 3/4" deep, reliable, all-aluminum tube-and-fin cooler extends the life and improves overall functioning of your Acura Legend's transmission.
Features:
Specs:
Note: The Derale Insta-dapt radiator adapter fits most Acura Legends with 5/16" transmission lines, but not all. In some cases, additional fittings or alteration of the OEM lines or hoses may be required for installation.
Perhaps the simplest type of heat exchanger, the tube-fin effectively cools a variety of automotive systems. The concept is simple: Fluid cools as it travels through the core by transferring heat out to the fins. The fins then provide the surface area necessary for sufficient heat exchange to take place, allowing the heat pulled from the fluid to dissipate into the surrounding air. Quick, easy and effective.

Today on our 2005 Chevrolet Avalanche, we'll be installing the Derale Transmission Cooler, part number D12906. We'll also be using the Derale Universal Mount Kit, part number D13002 and the GM Radiator Adaptor, part number D13035.Now our truck has had some modifications so the removal of the grill is different than normal, so we will not be showing it. With our grill out of the way, we'll go ahead and test fit the cooler.After finding a good spot for our cooler, using a couple of bolts and nuts we purchased separately, we'll attach the Derale brackets to the cooler. At this point, we want to leave the brackets loose until theyre mounted to the vehicle. We can go ahead and attach the rubber line to the cooler as well using two of the worm clamps. It also may be necessary to use some transmission fluid as lubricant to get the line around the fittings.We can now tighten down the worm clamp securing the rubber line to our cooler.
We will then place our cooler in its location and using a couple of self tapping bolts, we'll mount the cooler braces to the A-brace here on the truck. We'll do this on both sides. We can then tighten the brackets to the cooler. Now our cooler is secure and were ready to run the line. Going around the radiator, we'll pass the line through here to the factory cooler.Next, we'll need to identify the downstream transmission line.
This is the line that the transmission fluid is coming out of the factory transmission cooler in the radiator and heading back towards the transmission. To do this, we'll break torque the vehicle allowing the transmission fluid to warm up. The line that feels cooler is the one we'll be installing our new cooler into. We can then remove the holding device from the radiator and remove our line.Now, we'll take the GM adaptor and install it into the hole we removed the line from and reinsert the holding device. Now we'll determine where to cut our line in half on our new cooler.
Remember when cutting the line in half, youll want to leave enough room so the line doesnt kink. We'll slide the long end of our line onto the GM adapter here at the radiator, after sliding on another worm clamp where we can then tighten it down.We'll take the remaining clamp, slide it on the other line, slide the hose in, and tighten the clamp.Thats it, our transmission cooler is installed. We'll now go ahead and reassemble our truck, putting our grill back in place, as well as the headlights. Now all we need to do is check the fluid level and top it off as needed. We'll also want to make sure that there are no leaks.That completes our install of the Derale Transmission Cooler, part number D12906 in conjunction with the Derale Universal Mount Kit, part number D13002 and the GM Radiator Adaptor, part number D13035 on our 2005 Chevrolet Avalanche.

The transmission cooler, along with all the other products I ordered from etrailer was an excellent buy. they arrived on time and in excellent condition. The best benefit of ordering from etrailer is the superior customer service. I was even able to talk directly with one of their installers when I had a question. 17556

Very easy install, absolutely no leaks anywhere in the system after putting it into service. I did have to get additional hose for the install due to the location I chose for the cooler (personal preference). I centered it on the bumper side of the radiator to provide the best air flow. Remember to get a quart of transmission fluid to accomodate the larger system volume after the install. I took my grill off to provide the most room for putting the cooler in rather than trying to wedge it between the radiator and grill, made install the nylon fasteners through the radiator and cooler much easier. Should last for many years.61081

Ive got a 1999 4runner that had the unfortunate luck of having the integrated transmission cooler line rupture inside my radiator. needless to say, the transmission didnt agree very well with having engine coolant running through it and finally died out on me. I bought this transmission cooler to isolate the transmission and the engine cooling systems. The cooler arrived a day ahead of schedule, which is always a bonus. I didnt rate it at 5 stars because I havent had a chance to install it yet and see how it performs, but judging by the reviews that I have read so far, the customer service provided and the prompt delivery, I would say that this transmission cooler will keep my truck running for a good long while. Everything pictured arrived in the box and I have no doubt that it will perform as expected. I will definitely recommend this product and this company to my friends!30988
