Car Problems After Transmission Flush
Introduction
A transmission flush is a service that removes old transmission fluid and replaces it with new fluid. This service is often recommended to extend the life of the transmission and improve its performance.
However, in some cases, a transmission flush can actually cause problems. These problems can range from minor annoyances to major issues that require expensive repairs.
Minor Problems
Some of the minor problems that can occur after a transmission flush include:
- Shifting problems: The transmission may not shift as smoothly after a flush. This can be due to the new fluid being different in viscosity or friction properties than the old fluid.
- Slipping: The transmission may slip after a flush. This can be due to the new fluid not providing enough lubrication for the transmission components.
- Leaking: The transmission may leak after a flush. This can be due to the new fluid not being compatible with the transmission seals.
Major Problems
In some cases, a transmission flush can cause more serious problems, such as:
- Total transmission failure: The transmission may completely fail after a flush. This can be due to the new fluid causing damage to the transmission components.
- Clogged filter: The transmission filter can become clogged after a flush. This can restrict the flow of fluid to the transmission and cause it to overheat.
- Damaged clutch packs: The clutch packs in the transmission can become damaged after a flush. This can cause the transmission to slip or shudder.
Why Do These Problems Occur?
There are a few reasons why a transmission flush can cause problems. These include:
- The wrong fluid: Using the wrong type of transmission fluid can cause problems. The fluid must be compatible with the transmission and its components.
- Overfilling: Overfilling the transmission can cause fluid to leak out and cause damage to the transmission components.
- Flushing too often: Flushing the transmission too often can remove the protective additives from the fluid and cause damage to the transmission components.
How to Avoid These Problems
There are a few things you can do to avoid these problems, including:
- Use the correct fluid: Make sure to use the type of transmission fluid that is recommended by the manufacturer.
- Do not overfill: Check the transmission fluid level and make sure it is not overfilled.
- Flush the transmission less often: Only flush the transmission when it is necessary.
Conclusion
A transmission flush can be a beneficial service, but it is important to be aware of the potential problems that can occur. By following these tips, you can help to avoid these problems and keep your transmission running smoothly.
