What causes a transmission cooler to fail?
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. If left unattended, the transmission will run low on atf which will increase the fluid temperature and cause premature failure.
How does transmission fluid get to cooler?
How Does a Transmission Cooler Work? Fluid heated by the transmission, engine, or power steering pump flows to the cooler. Air flowing over the fins of the cooler carries away heat and cools the fluid flowing within the fins. The cooled fluid is routed back through the transmission via the return line.
Why do oil cooler lines fail?
The oil cooler lines can be damaged for many different reasons such as age, road debris, old oil or simply becoming clogged over time. If you are ever unsure what fluid is leaking under the car or would like a second opinion, get an oil and fluid leak inspection.

What happens if my oil cooler is bad?
When an oil cooler fails, it can force all the coolant out of the engine and raise the risk of an overheated engine, which may lead to possible engine damage. If the leak is significant, you’ll notice coolant on the ground or see steam gushing out from underneath the hood.
What happens when the gearbox does not receive cool oil?
When the gearbox does not receive cool oil due to oil cooler failure your gears do not shift properly. Improper gear shifts will create extra drag which the engine has to overcome. To do that the engine has to work harder than usual and that causes the engine to overheat.
Where does the oil go in a transmission oil cooler?
In a transmission oil cooler, this heat is channeled through the transmission oil. This oil moves from an outlet in the transmission to the radiator. The radiator cools the oil just as it cools the water, with the help of a coolant, and sends it back into the transmission.
What happens when the oil cooler adapter fails?
Oil in the cooling system. If the oil cooler adapter fails internally, you may notice engine oil in your cooling system. This happens because when the engine is running, oil pressure is greater than cooling system pressure. Oil is forced into the cooling system.
