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?
The most common transmission cooler failures are due to either a leak in the body of the cooler itself, or a clogged line caused by something flowing through the system. This most likely is from the transmission itself.
What fluid runs through transmission cooler lines?
How Car Transmission Lines Work. Car transmission lines connect your vehicle’s transmission to the vehicle’s radiator. Also known as transmission cooling lines, they are typically made of metal or composite aluminium and rubber hoses because they can handle the flow of hot transmission fluid.
How much does it cost to replace a transmission cooler line?
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.
How do I know if I need a transmission cooler?
Your vehicle’s gross vehicle weight rating (GVWR) is key to determining what kind of transmission cooler you need. As is the type of terrain over which you usually drive. Hilly and rocky terrain might require more of a heavy-duty transmission cooler.
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?
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.
Can you drive with a leaking transmission line?
While it is not especially dangerous to continue driving with a leaking transmission fluid, it can cause catastrophic damage to your engine. As soon as you notice your car is leaking transmission fluid, you should seek to contact a certified mechanic to have your transmission fluid serviced.

Should transmission cooler be before or after radiator?
Should the cooler be installed before or after the radiator? Answer: We recommend installing the auxiliary cooler after the radiator to return the coolest fluid directly to the transmission.
