This is a great addition to your vehicle if you're going to do a lot of towing with it.


Flex-a-lite Transmission Coolers FLX4120-6 Review

Today, we're going to take a look at the Flex-a-lite TransLife direct fit Tube & Fin Transmission Coolers. Now, this is a TransLife Transmission Cooler kit that will provide additional cooling to protect your transmission. A transmission cooler can reduce the transmission oil temperature by as much as 30%, and then cooler transmission oil, of course, will give you more reliable, consistent shifts. Under any extreme towing conditions, it will help prevent transmission damage. Now, this is designed to mount in front of the radiator, the air condition, or condenser. Inside the tubes that the oil flows through they do have turbulators and that helps circulate the oil, gives a superior heat transfer. This one is a six pass configuration, and that's because the tube will go or the oil will go in the tube six times through the condenser here.

As you can see, it's barely noticeable behind our upper grill opening where our Acura emblem is. This transmission cooler will help give us increased transmission life by reducing transmission temperatures during normal driving, hard driving, or when towing a trailer. Acura does recommend the use of a transmission cooler when towing a trailer with the MDX. All right, here's what our transmission cooler kit comes with.

We have our transmission cooler here.


Derale Transmission Coolers D12902 Review

Today we're going to take a look at the Derale Dyna-Cool Tube Fin transmission cooler kit. Now this kit will improve functioning and overall performance of your transmission. Basically, the fluid will cool as it travels through this core by transferring the heat out to the fins and then the fins will provide the surface area that's necessary for the sufficient heat exchange to take place, allowing the heat pulled from the fluid in the tubes to dissipate in to the air. It's a very quick, easy and effective way to cool your transmission. Now this will extend the life of your transmission and prolong its period between necessary fluid changes and it'll also cut down on heat related failures. The other nice thing is, inside the tubes where the fluid is flowing, they do have a built in embossed turbulator and what that does is it'll agitate the fluid as it goes through those tubes, for more efficient cooling.

  • Tow Capacity of 4x4 2007 Chevy Silverado Classic with 5.3L and Transmission Cooler Recommendation
  • You will want to first consult your vehicle owners manual but based on my research your truck has a standard towing capacity of 7,500 pounds and max towing capacity of 10,500 pounds. The max is usually either with the truck properly equipped or when using weight distribution. Your owners manual should be able to shed some light on this. Even with the truck properly equipped, and/or using weight distribution you will still be near the maximum of the truck. If a more capable truck is...

  • Which Transmission Cooler is Recommended for a Nissan Frontier with 6,500 Pound Towing Capacity
  • The best way to decide which class cooler you need is to take a look at what you will be towing and where. If you will be towing a light load, less than 2,000 pounds, in flat driving conditions, your vehicle will do fine with a Class I. If you will be towing 6,000 pound load through some hills, I would use the Class III cooler. I prefer the 8000 and 9000 series. They are built a little heavier and are more resilient. The 7000 series are built a little lighter and can be damaged more...

  • How to Determine Which Transmission Line is the Return Line for Installing a Transmission Cooler
  • The method we use to determine the correct line to install a transmission cooler on is pretty simple. You want to install the cooler on the return line. To determine which line is the return line you will want to start with your truck totally cooled off. Start the truck and put it in drive, apply the brakes firmly and then apply the accelerator slightly so that the rpms climb. Put the truck back in park and shut it off. Now go out and feel the two lines leaving the radiator. The cooler...

  • Ideally you want to keep the temperature of the transmission fluid in the 160 to 200 degree range. You cannot cool transmission fluid too much. Transmission coolers are universal fit items so you will want to measure the space you have in front of your air conditioning condenser or your radiator to see what size cooler will fit your 2008 Chevrolet Silverado 1500. Installing an additional transmission cooler in-line with the current transmission cooler would help in cooling the transmission...

  • Transmission Cooler Recommendation for a 2013 Chevy Silverado 1500
  • All vehicles with an automatic transmission have a factory transmission cooler. Normally it is located inside the radiator but it can also be outside of the radiator. Trucks that have a tow package often have a larger cooler that is outside of the radiator. Regardless of where your factory cooler is located, you can still add a supplemental cooler because transmission fluid cannot be over cooled. You are correct about towing in warmer weather and in the mountains. It will increase the...

  • Installing Derale Transmission Cooler to Replace OEM Cooler on 2007 Nissan Frontier SE
  • The Derale transmission coolers we sell are designed more as a supplemental cooler that is meant to augment the factory transmission cooler portion of the radiator, not replace it entirely. If you are experiencing the common problem with the radiator leaking causing the engine coolant contaminating the transmission fluid, your best bet really would be to have the original radiator replaced. I did a Google search using the keywords Nissan Radiator Problem and found that Nissan has extended...

  • Transmission Cooler Recommendations for a 2002 F-350 with the 7.3L Diesel
  • Transmission fluid should run below 200 degrees Fahrenheit. At 240 degrees you definitely need to make some sort of change to reduce the temperature. I would first recommend having the transmission checked by a qualified automotive technician to be sure it is performing properly. This will assure you that no damage has been caused to the transmission and you will not be stranded. Installing a transmission cooler will not reverse any damage that may have already been caused. If you find...

  • What is Correct Placement of Derale Dual-Pass Heat Sink Transmission Cooler # D13265
  • Maximum air flow will increase the heat exchange performance of any oil or transmission fluid cooler. This is true for flat plate-fin and tube-fin type coolers that typically mount in front of the air conditioning condenser as well as for heat-sink-type coolers intended for mounting on the frame rail. If mounted in a location that does not provide maximum air flow the cooler will still help to reduce the fluid temperature to some extent but it will not function at its best. If you prefer...

  • What do the Class Ratings Mean on the Transmission Cooler Pages
  • You can install a stack cooler in your vehicle. The Class ratings are there as a reference point to a hitch Class. For example if someone has a Class III hitch they can look at coolers, see a Class III and say, hey, I have a Class III hitch so this Class III cooler will be good for me. We tried to just make the choosing process easier by assigning a Class.

  • Transmission Cooler Recommendation for a 2011 Chevy Silverado with 5.3 Liter Engine
  • The optimum temperature for transmission fluid is between 160 and 200 degrees Fahrenheit (70 to 93 degrees Celsius) so at 240 (116 Celsius) you were definitely above that range. When towing up a high at low speeds using a low gear or towing mode, if available, would be the correct way to go about towing the trailer. I would recommend adding a transmission cooler to your 2010 Chevy Silverado. I would use a class III or higher cooler rated for at least 6,000 pounds. You can use # D13503...

  • Oil and Transmission Coolers for 1993 Dodge with 250 Cummins Diesel Operated in Desert Climate
  • Since oil and transmission coolers come in a range of sizes and types, and can mount in any location that will provide air flow (or in the case of fan-powered units enough space for convenient mounting) you can install both a secondary transmission cooler and a fan-powered oil cooler. I recommend using a secondary transmission cooler in addition to the OEM unit rather than bypassing it. The secondary cooler will take the already-cooled transmission fluid from the radiator and further...
