Transmission Fluid - When and Why To Change

Transmission Flushes - When and Why To Change | Airpark Auto Pros

You're cruising down the open road, the wind in your hair and the hum of the engine beneath you. But amidst this motion, a question lingers: When was the last time you treated your vehicle to a transmission flush? 

How Often Should You Flush Your Transmission?

The first order of business in the transmission flush saga is deciphering the ideal frequency for this maintenance procedure. While opinions may vary among experts, a general consensus suggests that a transmission flush is typically recommended every 30,000 to 60,000 miles. However, it's essential to consult your vehicle's owner's manual and consider factors such as driving habits, terrain, and the age of your vehicle when determining the appropriate interval for a transmission flush.

The Importance of Transmission Flush

Now, let's shine a spotlight on the significance of a transmission flush in maintaining the health and longevity of your vehicle's transmission system. 

At its core, a transmission flush serves as a preventative measure against the accumulation of sludge, debris, and contaminants that can clog up solenoids and actuators, compromising your transmission's smooth operation. By flushing out old fluid and replacing it with fresh, clean fluid, you're not only safeguarding against premature wear and tear but also optimizing your transmission's performance and efficiency for miles to come.

When NOT to Get a Transmission Flush

Amidst the fervor surrounding transmission maintenance, it's crucial to recognize that there are instances when a transmission flush may not be advisable. One such scenario is if your vehicle has significantly high mileage and has never undergone a transmission flush before. In such cases, the introduction of cleaners may dislodge accumulated deposits, leading to potential issues with shifting or transmission performance. 

Additionally, if your vehicle is experiencing transmission problems such as slipping, rough shifting, or fluid leaks, a transmission flush may exacerbate these issues rather than resolve them. In such cases, it's best to consult with a qualified technician who can diagnose the root cause of the problem and recommend an appropriate course of action.

Questions You Might Have

Is a transmission flush the same as a fluid change?

While both involve replacing transmission fluid, a transmission flush typically involves flushing out old fluid using specialized equipment and cleaners. In contrast, a fluid change involves draining the old fluid and replacing it with fresh fluid without flushing the system.

Can a transmission flush fix transmission problems?

While a transmission flush can help maintain the health of your transmission and prevent future issues, it's not a guaranteed fix for existing transmission problems. If your vehicle is experiencing transmission issues, it's best to consult with a qualified technician for a proper diagnosis and appropriate repairs.
