Car Needs Transmission Flush but No Check Engine Light
What is a transmission flush?
A transmission flush is a service that removes the old transmission fluid and replaces it with new fluid. This is typically done by connecting a machine to the transmission and running the engine for a period of time. The machine will pump new fluid through the transmission while removing the old fluid. A transmission flush is different from a transmission fluid change, which only replaces the old fluid with new fluid.
Why do I need a transmission flush?
There are a few reasons why you may need a transmission flush. These include:
- Dirty transmission fluid: Over time, the transmission fluid can become contaminated with dirt, metal shavings, and other debris. This contaminated fluid can cause the transmission to shift hard or erratically, and it can also lead to transmission failure.
- Overheated transmission: If the transmission overheats, it can damage the transmission fluid and cause it to lose its viscosity. This can lead to transmission problems, such as slipping gears or shuddering.
- Improperly installed transmission: If the transmission is not installed properly, it can cause the transmission fluid to leak. This can lead to low transmission fluid levels, which can cause transmission problems.
Symptoms of a dirty transmission
There are a few symptoms that may indicate that your transmission needs a flush. These include:
- Hard shifting: If the transmission is shifting hard, it may be due to dirty transmission fluid.
- Erratic shifting: If the transmission is shifting erratically, it may be due to dirty transmission fluid.
- Slipping gears: If the transmission is slipping gears, it may be due to dirty transmission fluid.
- Shuddering: If the transmission is shuddering, it may be due to dirty transmission fluid.
How often should I get a transmission flush?
The frequency with which you need a transmission flush will depend on your driving habits and the type of transmission fluid that you use. Most manufacturers recommend getting a transmission flush every 30,000 miles or 2 years, whichever comes first.
Can I do a transmission flush myself?
It is possible to do a transmission flush yourself, but it is not recommended unless you have experience working on cars. The process can be complex and if it is not done properly, it can damage the transmission.
How much does a transmission flush cost?
The cost of a transmission flush will vary depending on the type of transmission fluid that you use and the location of the shop. The average cost of a transmission flush is between $100 and $200.
Conclusion
If you are experiencing any of the symptoms of a dirty transmission, it is important to get a transmission flush as soon as possible. This can help to prevent transmission problems and extend the life of the transmission.
