Question: What does the transmission cooler line do?

The transmission cooling line system is vital to any automatic transmission. It circulates the hot fluid away to the radiator via cooler lines and returns the cooled fluid back to the transmission. A loss of fluid leading to an overheated transmission can be devastating as the system loses its ability to cool.

Can you drive with a bad transmission cooler line?

Driving your car with a bad transmission cooler is definitely not recommended. Because you will lose most of your transmission fluid while the car’s transmission is in operation and you are in motion, it is very difficult to know how much fluid you are losing, and at what rate.

What happens when 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.

What causes transmission cooler lines leak?

What causes a transmission line to break?

Over time, road debris and heat can cause the transmission fluid lines to crack or break, which can cause fluid to leak out. Another reason for lost fluid is your vehicle’s torque pump has become cracked or an axle seal has been compromised.

Are Transmission coolers 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.

Can a bad transmission cooler cause overheating?

Transmission overheating

When a transmission oil cooler hose fails it can cause the transmission to overheat. This can be due to low fluid level from a leak or preventing flow. In either case if the transmission overheats it can stop working entirely and this condition may be permanent.
