Frequent question: What causes transmission fluid to get in radiator?

If there was a rupture of the internal radiator tank can cause the coolant to mix with and contaminate transmission fluid. … Sometimes, a leak develops in the radiator between the coolant passage and the transmission fluid passage, and the coolant gets into the radiator.

What happens when coolant and transmission fluid mix?

There is a separate tank and hose in the radiator for transmission fluid. They allow the coolant to take heat away from the transmission fluid without mixing the two liquids. When a leak occurs, the transmission fluid and engine coolant mix with each other causing your transmission to seize up.

Can transmission fluid get in coolant?

Can low coolant affect transmission?

But if the engine coolant level is low, the coolant won’t immerse the transmission cooler properly. So the cooler won’t release the heat necessary for the transmission to cool off. The heat continues to increase in the transmission, causing parts to expand and pressures to build.

What does it mean when I have oil in my radiator?

If there is oil in your coolant or vice versa, it generally means there is a failure in one or more of your engine’s gaskets or seals.
