Utilizing a transmission cooler with a fan is best for applications where the cooler cannon receive enough air flow to keep the automatic transmission fluid temps cool enough.  The most common uses for high performance transmission oil coolers with a fan are typically on off-road type vehicles, drag racing applications, or even heavy duty towing.

In these situations, the cooler is either mounted under the vehicle or just simply isn’t getting the necessary air flow based on vehicle speeds.

Using a transmission cooler with a fan can often be confusing, so we want to help make things more simple.  Below are answers to common questions related to transmission coolers with fans. 

Do Transmission Coolers Need Fans?

No, transmission coolers do not need fans, but should use a fan where ever air flow is limited.  For example, if you mount your transmission cooler in an uncommon spot or in an area with little air flow, then a fan is highly recommended. 

This is common for heavy duty use cases or in situations where space is needed for other essential things such as a turbo kit on drag race vehicles. 

Do I Need To Buy A Transmission Cooler and Fan Separately? 

If you already have an aftermarket transmission cooler installed on your vehicle and need additional cooling, then yes, you will need to purchase a fan on its own and mount it to the cooler. 

However, if you know right off the bat that you need a fan, you can get a transmission cooler with fan kit as one simple to use unit.  This alleviates any headaches and matching of parts that may or may not work. 

Since transmission cooler with fan kits are sold as 1 piece, all the guesswork is eliminated, freeing up your valuable time and energy. All you’d need to do is mount the cooler and wire the fan to either a switch or with an in-line thermostat.

Transmission Cooler Thermostats & Fan Switches

Transmission coolers that utilize a fan can be turned on and off manually with a switch the driver controls or automatically with the use of an inline transmission cooler thermostat.  

Most transmission cooler thermostats activate the fan to turn on at 180F and turn off at 165F.  This helps keep the transmission fluid in a safe operating range, and will prevent overheating.
