Frequently Asked Questions (FAQs)

1. What are symptoms of a clogged transmission filter?

Symptoms of a clogged transmission filter include transmission fluid leaks, contaminated transmission fluid, shifting issues, strange noises, and unusual smells. It is important to regularly check your transmission fluid and address any signs of a clogged filter to prevent further damage to your lawn mower's transmission.

2. Will a dirty transmission filter cause hard shifting?

Yes, a dirty transmission filter can cause hard shifting. It can lead to issues such as noise when in neutral and difficulties switching gears. If you experience these symptoms, it is recommended to check and clean or replace the transmission filter to ensure smooth and proper shifting of your lawn mower.

3. Can you clean out a transmission filter?

While it is possible to clean a transmission filter yourself using disc brake cleaner, there is a higher risk of damaging the filter. It is generally recommended to replace the transmission filter rather than attempting to clean it, especially to ensure optimal performance and avoid potential damage to the lawn mower's transmission system.

4. How long do transmission filters last?

Most lawn mower manufacturers recommend changing the transmission filter every 30,000 miles or every two years, whichever comes first. It is important to follow the manufacturer's recommendations to maintain the efficiency and longevity of the transmission system in your lawn mower.

5. What to do if transmission is shifting hard?

If your lawn mower's transmission is shifting hard, it may be due to worn transmission fluid. Over time, the fluid's frictional properties can degrade, leading to hard and jerky shifts. In this case, it is recommended to change the transmission fluid to restore smooth shifting and prevent further damage to the transmission system.

6. What are the different types of transmission filters?

There are two types of transmission filters for lawn mowers: internal and external filters. External filters are attached to the transmission housing and can be found on older automatic transmissions. It is important to identify the type of filter your lawn mower has to ensure proper maintenance and replacement when needed.
