On most vehicles, the transmission oil will heat up but there is not enough friction in a properly operating transmission to heat up the oil to a dangerous level. However, if you have a performance or high powered vehicle, such as a tow vehicle, you may need to have some additional cooling systems in place to keep the transmission oil from overheating and breaking down. That is why Flexalite offers the Flexalite transmission cooler. The Flexalite transmission cooler is essentially a small radiator. The air passing over that radiator is enough to keep it cool, and you should not have to worry about any addition airflow issues. The Flexalite transmission oil cooler is designed to preserve the live of your transmission oil and your transmission. All vehicles have temperature gauges for coolant, and a few have gauges for oil temperature, but there is no street vehicle with a transmission oil temperature gauge, meaning that you will have no idea if your transmission is overheating. If you think you may be running dangerous temperatures in your transmission, you should install Flexalite transmission oil cooler.
