1961 AMC Rambler American - Derale Series 9000 Plate-Fin Transmission Cooler Kit w/ NPT Inlets - Class I -Extra Efficient

  • Plate-Fin Cooler
  • With 1/2 Inch NPT
  • 11W x 3-7/8T x 1-1/4D Inch
  • Standard Mount
  • Derale

11" Wide x 3-7/8" tall x 1-1/4" deep, radiator-style heat exchanger improves the performance and overall functioning of your AMC Rambler American's transmission. Includes hose-barb adapters to fit the 1/2" NPT inlets.


  • Prolongs life of transmission
  • Improves overall performance
  • Prevents heat-related failures
  • Has furnace-brazed aluminum construction and 1-1/4" wide turbulator plates for more efficient cooling
  • Includes complete mounting kit, OEM spec hose with stainless steel clamps, Insta-dapt radiator adapter and hose-barb fittings
  • Sleek design makes this ideal for use in compact cars


  • Inlets: 1/2" NPT
  • Fittings: 1/2" NPT x 3/8" hose barb
  • Overall dimensions: 11" wide x 3-7/8" tall x 1-1/4" deep
  • Distance between inlets: 8-7/8"
  • Mounting dimensions: 6-3/4" wide x 3" tall

Note: The Derale Insta-dapt radiator adapter fits most vehicles 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.

One of the more popular cooling systems available, the radiator-style, plate-and-fin heat exchanger provides increased surface area so that fluids can spread out along the finned chambers to cool faster. In addition to the increased surface area, this cooler also features turbulator technology, whereby fluids are agitated continuously, not only to facilitate heat transfer, but also to prevent any undesirable drop in pressure.

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.

worked as described

Review from a similar Series 9000 in Transmission Coolers

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.

  • How Does Supplemental Transmission Cooler Work with Factory Cooler of 2003 Ford Escape
    When installing a transmission cooler the best solution is to install the supplemental cooler after the factory cooler so that you get the cooling power of both coolers. That is what I would recommend when installing an a cooler on your 2003 Ford Escape.

  • Transmission Cooler for 2005 Honda Accord V6.
    The Derale # D13611 transmission cooler isn't designed to replace the factory transmission cooler, it's designed to supplement it. The cooler installs inline on the return line from the factory cooler back to the transmission. The heat exchanger portion would ideally be installed directly behind the grillwork, in front of the radiator. If you use the provided link, my buddy David will run through how the cooler works. I'll also link to some help articles about transmission coolers.

  • Transmission Fluid Needed for Transmission Cooler Installation
    When you install the Derale Series 9000 Plate-Fin Transmission Cooler # D13611 a little extra fluid will be needed. The last part of the installation instructions have you add fluid as needed and then drive the vehicle for a little while and recheck the fluid level. Not much additional fluid is needed unless much is spilled when you disconnect and reconnect the lines. Normally just a few ounces of fluid is needed.

  • Aftermarket Transmission Cooler Installation for Mitsubishi Vehicles
    It would not surprise me if Mitsubushi OEM transmissions had a function that stopped the flow of transmission fluid out of the transmission when the transmission is cold. I do not believe that this option would be installed outside of the transmission, because there would need to be a bypass hose and valves in the transmission output and return lines, causing a complicated installation at the factory.

    The Derale Series 9000 Plate-Fin Cooler # D13611 would be an excellent choice for use on your 2011 Nissan Maxima. Transmission coolers are not vehicle specific, but there are coolers that are recommended based on available mounting locations of your vehicle. It is always recommended to use the most efficient mounting location that is possible. Typically this is located between the AC condenser core and the grille.

  • Are Additional Fittings Needed to Install Transmission Cooler on a 2008 Nissan Armada SE 5.6L
    You should not have to worry about that warning since it is uncommon. The transmission cooler # D13611 comes with an Insta-dapt fitting that you can use to avoid have to flare the steel or aluminum lines. The worst case scenario is that you would have to flare the metal lines, if applicable. If the lines are aluminum you can flare them with a Phillips screwdriver. Steel lines would require a flare tool which your local auto parts store should have. But I do not think that will be necessary...

  • Compatibility of Transmission Cooler with Automatic Transmission on 2006 Toyota Corolla
    You will want to install the cooler on the return line. You can identify which one is the return by starting out with the engine cold, starting it, shifting into gear for about 10-seconds and then back to park, then shutting the engine off. Feel the two lines; the cooler one is the return line. Please note that when you add a cooler like Derale # D13611 (or a larger one) that is confirmed to fit your car you naturally also add a requirement for additional fluid. Toyota insists that only...

For a vehicle like yours that won't be towing anything ever most likely you wouldn't really need one. But they can't hurt.

  • Best Transmission Cooler Fit for the 2010 Mercury Mariner & 2011 Ford Escape
    The best transmission cooler that will fit and works best for your 2011 Ford Escape and 2010 Mercury Mariner is the Derale Series 9000 Plate-Fin Transmission Cooler Kit w/Barb Inlets, # D13611. This fan measures 11" wide x 3-7/8" tall x 1-1/4" deep to provide the correct fit on your vehicles. This cooler works the best because it features turbulator technology, whereby fluids are agitated continuously, not only to facilitate heat transfer, but also to prevent any undesirable drop in pressure.

  • Can Transmission Cooler be Installed on a Vehicle with Sealed Transmission
    Sealed transmissions make installing a transmission cooler a bit more interesting since there isn't an easy way to add or check fluid. There may not be a dipstick on your transmission, but there is drain and fill plug. You are going to have to use a lube pump to get the proper amount of fluid in the vehicle so honestly your best option is going to be to have a transmission shop do the install since they will have the equipment needed. Prefilling the cooler might get you pretty close...

  • Transmission Cooler for a 2016 GMC Terrain Denali with 3.6 Liter V8
    Yes you can use the Derale transmission cooler # D13611 on your 2016 GMC Terrain. The cooler will help the fluid run at a lower temperature which is better for the transmission so that you will get the most life out of it. Installation is not all that difficult. Take a look at the video I have linked showing an example installation on a vehicle. Installation will be similar on your Terrain.

  • Which Transmission Cooler for 2005 Nissan Frontier
    The best place to install a transmission cooler is directly behind the grille, in front of the radiator and A/C condenser. We recommend choosing the largest cooler that will fit in the space available, so you will need to measure to see how much room you have. You cannot over cool a transmission. The # D13503, which measures 11x8-3/4x7/8 inches is what I would recommend, assuming that there is enough room behind the grille. You might need to remove the grill and front bumper cover in...

  • Comparing Different Types of Transmission Coolers for a 2006 Subaru Outback Wagon
    The reason you do not see any cooling capacity figures for a transmission cooler is because there are just too many variables at hand to give any sort of accurate estimates. These variables have to do with ambient temperature, mounting location, etc. That said, there is a way to compare the coolers and that is by their construction; tube-and-fin (least efficient), plate-and-fin (moderately efficient), stacked-plate (most effective).

  • Transmission Cooler Replacement Recommendation for 2005 Nissan Xterra
    Sounds like you are wanting to bypass the transmission cooler of your 2005 Nissan Xterra to prevent the known issue they have of having it leak into the radiator. We can easily help with that. What you'll want is a replacement supplemental cooler to bypass it with something like the # D13504 and you'd be set. This would do a better job than the factory cooler sine it's larger and a more efficient design and would allow to no longer have to worry about the milkshake issue.
