What happens if water gets into your transmission?

Water in the transmission fluid is highly destructive. Your vehicle’s transmission is made up of sensitive parts that quickly deteriorate when exposed to water. Contamination of the friction plates in the transmission will result in the transmission no longer being able to shift into any gears.

How does water get into a transmission?

How does water get into the transmission? … Water can come from the radiator or an external source. 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 low coolant cause transmission problems?

How do you drain transmission fluid?

The trick on how to drain transmission fluid is to work from the top, sucking out the old fluid up through the filler tube. Then refill with fresh fluid. A hand-operated vacuum transmission fluid pump makes the job simple and clean. You can remove one-third to one-half of the fluid from the transmission at a time.
