What is a transmission cooler?

Is a transmission cooler necessary?

For every 20F degree drop in transmission fluid temperature, you can expect to extend the fluid and equipment life, thereby extending the life of the vehicle. That’s why it is very important to have a quality transmission cooler, and more importantly, to have it professionally installed.

How much does a transmission cooler cost?

You will pay somewhere between $100 and $450 for a transmission cooler line replacement. The labor should be between $60 and $300, while parts can cost you anywhere from $40-$160.

Do all vehicles have transmission coolers?

While all automatic transmission equipped vehicles have a transmission cooler in their radiator, this might sometimes not be enough to properly cool your transmission fluid.

What fluid runs through 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 a transmission run too cool?

Heat is a huge cause of transmission failures but running too cool is bad also. Just as an engine has to run hot enough the trans has to run hot enough to get rid of any condensation that builds up inside and to keep the viscosity at the correct level for best operation.

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 .

Does transmission cooler increase performance?

When mounted in an area that sees direct air flow, such as behind the grille, a stacked plate cooler will be extremely effective in keeping everything running smoothly. As horsepower and torque increase so will the size of the cooler to an extent, but also consider driving style as part of the equation.

Can I run two transmission coolers together?

In series is fine. One in front of the other will be a not be much more effective than just one. One reason is the air that goes thru the front cooler gets heated up and is less effective as it goes thru the rear.
