How do you know if your transmission fluid is contaminated?

What problems can dirty transmission fluid cause?

Excess dirt and contaminants in the transmission can cause a loss of hydraulic power, therefore keeping the transmission from staying in the appropriate gear. A dirty transmission can quickly start to interfere with transmission fluid flow, resulting in the lack of pressure needed for the transmission to stay in gear.

How does transmission fluid get contaminated?

The fluid passes through a small tank inside the engine’s radiator. 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.

Considerations. If your automobile’s transmission fluid gets too low, it usually means that it has a leak in its transmission system. This is because transmission fluid does not gradually burn away, like engine oil. It can only be lost through leakage.

How do I know if my transmission fluid is in my coolant?

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.

What happens if water gets in transmission fluid?

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.

Does 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.

Signs of a Clogged Transmission Filter

Rattling Noises – Rattles can come from many places, but if you’re hearing a jiggling rattle or a metal-on-metal sound, and it’s not from an obvious source, then check on the transmission. If the fluid looks dark, it may be because the filter is clogged and is restricting flow.

How often should transmission fluid be changed?

Manual transmissions generally need transmission fluid changes more frequently than automatic transmissions. The average recommended interval for manual transmissions is around 30,000 to 60,000 miles. For automatic transmissions, the recommended interval is around 60,000 to 100,000 miles.

Will a transmission flush fix my transmission?

A transmission flush will help to reduce the need of transmission repair, help your vehicle shift gears easier and help to improve overall engine performance.

Can a transmission flush hurt your transmission?

Almost every car manufacturer recommends against using transmission flushing chemicals, and most will void your transmission warranty if they can prove these chemicals are being used. These chemicals can damage your transmission, which is why most automakers recommend against them.

Is it better to flush or drain transmission fluid?

A transmission fluid change doesn’t remove all of the fluid, but is still effective in replacing most of the dirty fluid. A transmission flush is very effective because all of the old fluid is removed using a flush machine and then new fluid is added.
