What are the benefits of a transmission cooler?

Is a transmission cooler a good idea?

As long as it is properly installed, a transmission cooler will not affect a factory transmission. It is a flow-through device and does not affect any internal components of the transmission. … Transmission fluid cannot be cooled too much, so the addition of a cooler is a good idea, especially if you are towing.

Does a transmission cooler add horsepower?

These types of coolers have been around as long as the automatic transmission and for the most part do an effective job of keeping the transmission going for many thousands of miles. … When we increase the torque and horsepower output of our engines we also increase the stress applied to the transmission.

What is the purpose of a transmission cooler?

Is a bigger transmission cooler better?

The larger the cooler, the better it will be at lowering fluid temperature. The plate and fin and the stacked plate coolers offer a larger surface area to cool transmission fluid faster and better, which is why they are so popular.

Can a transmission cooler be too big?

Too big could be a concern if mounted in the front of the rad creating a loss of air flow to keep the engine cooled . Years ago , GM released a TSB about overcooling the transmission in cold climates . Transmission fluid would actually turn to somewhat of a gel .

How do I keep my transmission cool while towing?

Adding a simple auxiliary cooler inline with the factory unit can nearly double the life of transmission fluid, keeping your gearbox happy and healthy for a long time. Also helpful are aftermarket aluminum pans. Their added fluid capacity and finned heat-sink design provide additional cooling as well.

Should transmission cooler be before or after radiator?

Answer: We recommend installing the auxiliary cooler after the radiator to return the coolest fluid directly to the transmission. Installing the cooler before the radiator will still provide additional cooling and may be necessary in some difficult-to-access applications.

What fluid runs through a transmission cooler?

A transmission cooler operates like a heat exchanger mounted adjacent to your car’s radiator. Hot transmission fluid flows through the unit and comes in contact with a series of fins or plates.

Does radiator cool transmission fluid?

All transmissions have a cooling line that runs to the radiator. A separate fluid passage circulates the transmission fluid through a portion of the radiator to cool the fluid.

What fluid goes in a transmission cooler?

Transmission oil can reach extremely high temperatures during operation, and this fluid can be cooled down with an external oil radiator. Some vehicles manufactured after 1975 will have transmission coolers built into the car’s radiator, as will most trucks designed for towing.

Can you put a transmission cooler on a CVT transmission?

A Hayden by-pass cooler can be used in these applications. Many vehicles now feature CVT transmissions and use a liquid-to-liquid cooler for the transmission.

Is a transmission cooler the same as an oil cooler?

Engine oil coolers are designed for greater pressures and temperatures than transmission or power steering fluid coolers. This means you need to know what the cooler you have in mind is designed for. You do not want to run a transmission or power steering fluid cooler as an engine oil cooler.
