What is a Transmission Cooler and What Does it do?

Gearbox coolers allow transmission fluid to flow through them, keeping transmission temperatures within an acceptable range. The gearbox cooler uses incoming air to help dissipate the heat given off by the hot transmission fluid and cool the fluid as it flows through the cooler.

This universal theory encourages you to push your car without thinking about transmission oil overheating. If the transmission oil temperature rises to dangerous levels, it can cause permanent damage or even a breakdown.

How Does a Transmission Cooler Work?

The transmission oil cooler works by dissipating heat produced by hot transmission oil flowing through its core. For example, tube and fin coolers can use ambient air to cool the fins as the fluid flows through the cooler tubes.

The air flowing through the moving cooler is how the gearbox cooler lowers the temperature of the gearbox fluid. Therefore, it is important to mount the aftermarket transmission cooler in an area with strong air circulation (e.g., in front of the radiator and air conditioning condenser).

Depending on the program, it may be necessary to install a remote transmission cooler. Since the cooler cannot receive sufficient air movement, there are other alternatives, such as installing a dedicated gearbox cooler with a fan or a radiator-type gearbox cooler.

The diagram below illustrates how the hot fluid passes into the cooler and cools as it begins to move.

Benefits Of Transmission Coolers

Gearbox coolers have a wide range of applications. The main one, as the name suggests, is gearbox oil cooling. The gearbox cooler not only keeps the fluid temperature down but also helps to prolong the existence of the gearbox oil. If the gearbox oil gets hot, it starts to break down, and its function of assisting the internal mechanism of the gearbox decreases.

The ideal temperature range for gearbox oil in most automobiles is 160-180 degrees. Although newer cars may cool more, it is advised that the 4l60e be kept within this temperature range.

The graph below shows the impact of heat on the gearbox and the period it takes to malfunction. Fire, as they say, is the biggest gearbox killer, so keep the gearbox oil as cool as possible.

Types Of Transmission Coolers

When mounting auxiliary gearbox coolers on your car, you have three options: tube fin, plate, and stacked plate coolers. There is also a fourth form of cooler known as a radiator or rack-mounted cooler.

Each form of gearbox cooler has advantages and disadvantages, so you should evaluate which cooler is best for you based on your application.

Tube & Fin Transmission Coolers

The tubular finned transmission cooler is a transparent straddle cooler, as the name implies. It has external fins for heat dissipation and a tube shape to allow fluid crossflow. This radiator is fairly simple and can handle most typical driving activities.

In general, this is not the hottest most cost-effective form of transmission. Since the tube through the cooler has a limited surface area in contact with the heat sink, the cooler cannot transfer fluid heat as easily as other forms of coolers.

Plate & Fin Transmission Coolers

The plate-fin radiator differs from the tube-fin radiator in that it employs parallel plates that run horizontally across the radiator. This radiator may appear identical to conventional radiators. Transmission oil passes through the rows of plates to produce more efficient cooling, unlike tube-and-fin type coolers, which typically have a larger surface area region.

Plate and fin coolers are more expensive than tube coolers, but they are also very cost-effective. The average cost of these types of coolers ranges from $30 to $70, depending on size and GVWR.

Hayden Motors, which is known for making some of the best gearbox coolers at a fair price, manufactures some of the most popular plate and fin coolers.

Stacked Plate Transmission Coolers

When comparing stacked plate coolers to tube and fin coolers and plate and fin coolers, they have the highest cost but the most cooling power and are the most common type of gearbox oil cooler.

This cooler has stacked shrouds, identical to those of a plate and fin cooler, giving it the appearance of a heat sink. To reduce temperature, stacked plate coolers force fluid into the cooling plates. In comparison, stacked plate coolers have more cooling banks than plate and tube coolers.

B&M is a pioneer in the stacked plate drive the cooler market. Its products are well known in the industry for their good efficiency and superior gearbox cooling capability.

Heat Sink Transmission Coolers

Gearbox radiators are certainly the least common gearbox coolers, but they do have their uses. Radiator gearbox coolers are usually mounted on the frame rails of older vehicles with restricted space.

Transmission oil flows into one or two cooling banks (channels) in these coolers. The cooler, including tube and fin coolers, employ fins to help dissipate the heat produced by the transmission oil.

These coolers will have adequate cooling power for a fun weekend vehicle, but not for any serious gearbox loading.

4l60e Transmission Cooler [Buying Guide]

The performance of the 4160e gearbox is calculated based on the gearbox cooler chosen. Therefore, it is critical to choose a gearbox cooler capable of releasing the maximum power of the 4160e gearbox cooler. The following are the main factors to consider when purchasing a 4160e gearbox cooler.


The first important thing to remember when purchasing a transmission radiator for your 4160e transmission is compatibility. The last thing you want is to purchase a radiator only to find out that it is incompatible with your 4160e transmission. You need to remember that 4160e transmissions are not compatible with all transmissions on the market. So before making a final decision, check to see if it is compatible with your transmission. Fortunately, most manufacturers already specify compatible transmissions for their coolers.

Material and Design

The primary function of the gearbox cooler is to prevent the gearbox from overheating. The effectiveness of the cooler in reducing transmission oil temperature is determined by the content and configuration of the transmission oil. Aluminum coolers, for example, perform better than steel coolers. This is due to the excellent heat dissipation properties of aluminum, as well as its resistance to wear. In addition, a transmission radiator with a wider surface area performs better in terms of cooling than a transmission radiator with a narrower profile.


Some gearbox coolers can only be repaired by a professional technician, while others can be repaired by the user. If you want to assemble the gearbox cooler by yourself, you should choose an easy-to-install cooler. Please do some study to find an easy-to-install 4160e gearbox cooler. The instruction manual provided to you should be simple and quick to follow.


The total mass of the vehicle as defined by the manufacturer is referred to as the GVWR. This encompasses the combined weight of the vehicle components, occupants, and cargo. It is important to consider a gearbox cooler for a car that can be safely used in the car before purchasing. GVWRs typically range from 10,000 to over 30,000 pounds. The higher the GVWR rating, the more transmission fluid the car uses and the need for a more powerful cooler to save it from overheating.

Type of Transmission Cooler

There are three different styles of 4160e coolers to choose from. Tone and fins, stacked boards and frames, and fins are some of them. Each transmission mode has advantages and disadvantages. For example, although tube and fin type transfer coolers are less expensive, their heat transfer effect is inferior to other coolers. Choose a gearbox to match your 4160e that offers excellent cooling efficiency.


4160e gearbox performance is defined by the type of gearbox cooler you choose. A decent 4160e gearbox cooler should meet your vehicle’s requirements and have an adequate cooling capacity for heavy gearbox loads. If you are looking for the best transmission cooler for 4160e, we suggest any of the options mentioned above. They have been extensively tested and confirmed to provide superior cooling efficiency. They are reliable, durable, and are reasonably priced.
