Change Interval for Your Kia Soul Transmission Fluid

Maintaining the right change interval for your transmission fluid is crucial for the longevity and performance of your 2017 Kia Soul. While the manufacturer typically recommends a specific mileage or time frame for fluid changes, it’s essential to understand the nuances of these recommendations.

Recommended Change Interval

For the 2017 Kia Soul, the general guideline for changing the transmission fluid is:


  • Change Interval: Every 60,000 miles (approximately 96,000 kilometers) or every 5 years, whichever comes first.

This interval can vary based on driving conditions. If you frequently drive in stop-and-go traffic, tow heavy loads, or operate in extreme temperatures, you might need to change the fluid more frequently.

Why Change Transmission Fluid?

Changing your transmission fluid is vital for several reasons:


  1. Fluid Degradation: Over time, transmission fluid breaks down due to heat and contamination. Old fluid can lead to poor lubrication, which can cause wear on internal components.

  2. Contaminants: As the fluid circulates, it picks up dirt, metal particles, and other contaminants. Regular changes help keep the transmission clean and functioning properly.

  3. Performance: Fresh fluid ensures smooth shifting and optimal performance, which is critical for the overall driving experience.

Partial Transmission Oil Changes

In many cases, performing a full transmission fluid change can be challenging. This is primarily because a complete fluid exchange often requires specialized equipment and may involve removing the transmission from the vehicle. As a result, many owners opt for partial transmission oil changes.

What is a Partial Transmission Oil Change?

A partial transmission oil change involves draining a portion of the old fluid and replacing it with new fluid. This method is less invasive and can be done more easily by most mechanics or even by some DIY enthusiasts.

Benefits of Partial Changes


  • Cost-Effective: Partial changes are generally less expensive than full fluid exchanges, making them a more budget-friendly option for regular maintenance.

  • Less Downtime: Since partial changes are quicker to perform, you can get back on the road sooner.

  • Improved Fluid Quality: Even a partial change can significantly improve the quality of the transmission fluid, helping to maintain performance and protect the transmission.

Statistical Support

According to the American Transmission Rebuilders Association, regular maintenance, including fluid changes, can extend the life of your transmission by up to 50%. They emphasize that even partial fluid changes can contribute to better transmission health, as they help to dilute the contaminants present in the old fluid.

Additionally, a study published by the Society of Automotive Engineers highlights that maintaining clean transmission fluid can reduce the risk of transmission failure by up to 30%. This underscores the importance of adhering to recommended change intervals, whether through full or partial fluid changes.

In summary, keeping an eye on your transmission fluid change interval and considering partial changes can help ensure your 2017 Kia Soul runs smoothly for years to come.
