What happens if you put antifreeze in transmission fluid?

Will antifreeze ruin a transmission?

Engine coolant surrounds the tank to help keep the fluid inside at a constant temperature. Any rupture of the internal radiator tank can allow coolant to mix with, and contaminate transmission fluid.

Can you mix antifreeze and transmission fluid?

Transmission oil mixing with coolant is a serious problem that needs immediate attention. If you’re lucky enough to catch this early, you can save yourself a ton of repair bills. A faulty transmission cooler will allow coolant and transmission oil to mix.

How does antifreeze get in transmission?

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. Sometimes, a leak develops in the radiator between the coolant passage and the transmission fluid passage, and coolant gets into the radiator.

What are the symptoms of dirty transmission fluid?

What happens when transmission fluid overheats?

A transmission that frequently overheats can cause fluid to leak from the transmission, so if you are constantly replacing the fluid, it’s a good indication of a leak. A slipping transmission is also an indication of low, dirty, or burnt transmission fluid.

How can you tell the difference between transmission fluid and antifreeze?

Look at the color of the transmission fluid. Fresh transmission fluid is a bright red color due to dye that is added to the fluid. If the fluid is a milky pink color, it has either antifreeze or water in it.

Can you mix transmission fluids?

The most common situation where the wrong transmission fluid is used is in the case of using automatic transmission fluid in place of variable transmission fluid and vice versa. Adding ATF to a to a CVT will eventually result in the death of your transmission.
