Why does transmission fluid go through the radiator?

Why does transmission fluid go through the radiator?

If there was a rupture of the internal radiator tank can cause the coolant to mix with and contaminate transmission fluid. All transmissions have a cooling line that runs to the radiator. A separate fluid passage circulates the transmission fluid through a portion of the radiator to cool the fluid.

Can transmission fluid leak into the radiator?

Transmission fluid will leak from the heat exchanger into the radiator where it contaminates the engine coolant.

Can a bad radiator cause transmission problems?

When the engine and radiator do not receive the right flow of coolant, then it it can cause radiator problems. If a faulty radiator is not repaired, then it could also cause damage to the transmission if the transmission fluid is cooled using the radiator.

What does it mean when your transmission fluid is milky?

The milky substance you are seeing on the transmission dipstick is a result of cross-contaminated coolant and transmission fluid. More than likely, your radiator has failed which has allowed coolant to enter the transmission system. When coolant enters the transmission, it will cause failure very quickly.

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.

Can you put transmission fluid in the radiator?

Make sure it’s not transmission fluid. If you have a look at the radiator and you’ll notice the radiator has two metal pressure lines on the same side one near the top and on near the bottom of the assembly. These lines come from the transmission to the transmission cooler that is integrated into the radiator.

What happens if you mix transmission coolant with transmission fluid?

This needs to be fixed as soon as possible, like today, as the coolant mixed with your transmission fluid will seriously damage your transmission. The transmission cooler goes through the radiator in a lot of cars, especially GM. They use the heat from the coolant to warm the transmission quickly, and to cool it off.

What should I do if my transmission fluid is red?

If however your transmission fluid is red, you’ll likely simply need to verify the fault – rupture of radiator to transmission cooler seal. It’s not uncommon for a radiator to transmission cooler to only leak under certain conditions. Such as, for example only when warm, not when hot or cold.

What does it mean when the transmission fluid sticks to valves?

It also means the valve body is being contaminated, and the steel pieces in it are rusting. This will eventually lead to sticking valves. Because your transmission cooler in your radiator has broken causing transmission fluid to enter the coolant. But there is worse news than that. It also means that coolant has entered the transmission fluid.
