Best Transmission Cooler: Your Definitive Buying Guide

The transmission can be a source of numerous problems for your car, which can give you a headache, aside from the fact that they can be costly to repair. The good news is that there are many ways by which you can prevent the possibility of overheating. In this case, one of the best things that you can do is to invest in the best transmission cooler. Unless you already have one, you’ll never know how it can deliver a wealth of benefits.

While there are many options in the market, this should not be an excuse for you to decide in haste. If you are clueless about which to purchase, keep on reading this guide, and we’ll help you to come up with the right decision. We will have a quick look at five of the best products that you may want to consider.

What Is A Transmission Cooler

Obviously, this is equipment that has the primary role of cooling the transmission. It is a thin and square-shaped component which is placed near your radiator. It will be effective in cooling the transmission fluid, and, in turn, will prolong the functional life of your transmission. The engine will also be cooled. Once the fluid becomes hot because of power steering or the engine, it will be directed to the cooler. After cooling the fluid, it will be re-routed to the transmission through a continuous loop.


While there are many benefits that can be yielded by the transmission cooler, proper installation should be given attention. It will effectively protect the engine as well. Also, it should be pointed out that not all transmission coolers will work for all cars. You have to research about compatibility as you decide which one should be purchased.

Types of Transmission Coolers

As you try to narrow down the possibilities and reach the right decision, one of the most important things is to decide on the specific type of transmission cooler that you will need. While they are basically the same in terms of their functions, the difference lies in the manner by which they can cool fluid. With this, below are three of the options that you can find:

  • Tube and Fin Cooler: One of the distinct characteristics of this type is the presence of a weaving tube that surrounds the transmission cooler. The main role of these tubes is to make sure that the fluid will be distributed around. It comes with a practical price and will work even for older models of cars. However, of the three types, this has a negative reputation because of its minimal efficiency.
  • Plate and Fin Cooler: The mechanism is almost the same as the previously mentioned, with the only difference being that the plate and fin cooler are better when it comes to efficiency. The tubes run horizontally, and fluid passes through each row. It is compact and can cool a generous amount in a given time.
  • Stacked Plate Cooler: Of the three types, this is the most efficient one. There is no wonder why it is also the favorite amongst many people. In terms of appearance, they are similar to plate and fin coolers. The large size of the turbulator is one of its best features, which will help in increasing airflow. If there is one drawback, it would be the fact that it comes at an expensive price.
