How do you know if your transmission cooler is bad?

You hear odd noises coming from the transmission: Your transmission may have difficulty shifting between gears, or there may be clunking or grinding noises during shifts. This can indicate transmission fluid loss, high internal transmission temperatures, or both, which can be caused by a bad transmission cooler.

What runs through transmission cooler lines?

Fluid heated by the transmission, engine, or power steering pump flows to the cooler. The air moving over the fins of the cooler cools the fluid, which is then routed back to the transmission, engine or power steering pump in a continuous loop through the return line.

What happens if transmission cooler line breaks?

Like all parts of an engine, transmission cooling lines can wear out. If they break or develop a leak, you will lose transmission fluid, leaving your car vulnerable.

It may be due to a poor or faulty connector, which connects the lines to the transmission and radiator, respectively.

Is 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.
