Change Interval for Your Highlander’s Transmission Fluid

Maintaining the right change interval for your transmission fluid is crucial for the longevity and performance of your 2017 Toyota Highlander. While the manufacturer recommends specific intervals, real-world driving conditions can affect how often you should change your fluid.

Recommended Change Intervals

For the 2017 Toyota Highlander, the general recommendation for changing the transmission fluid is every 60,000 to 100,000 miles (approximately 96,000 to 160,000 kilometers ). However, this can vary based on several factors, including driving habits, climate, and the type of driving you do (e.g., city vs. highway).

Factors Influencing Change Intervals

Several factors can influence how often you should change your transmission fluid:

• Driving Conditions: Frequent stop-and-go traffic, towing, or driving in hilly terrain can cause the fluid to break down more quickly.


• Climate: Extreme temperatures, whether hot or cold, can affect fluid performance. Hot climates can lead to quicker degradation of the fluid.


• Vehicle Usage: If you use your Highlander for heavy-duty tasks, such as towing or off-roading, consider changing the fluid more frequently.

Partial Transmission Oil Changes

In many cases, a full transmission fluid change involves removing the transmission from the vehicle, which can be both time-consuming and costly. This is where partial transmission oil changes come into play.

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 without completely removing the transmission. This method can be beneficial for maintaining fluid quality without the need for extensive labor.

Benefits of Partial Changes

Here are some reasons why partial transmission oil changes can be advantageous:

1. Cost-Effective: Partial changes are generally less expensive than full fluid changes, making it easier to keep up with maintenance.


2. Less Downtime: Since partial changes require less labor, your vehicle will spend less time in the shop.


3. Improved Fluid Quality: Regular partial changes can help maintain the quality of the transmission fluid, preventing the buildup of contaminants and prolonging the life of the transmission.

Statistical Support

According to the Automatic Transmission Rebuilders Association (ATRA), regular maintenance, including fluid changes, can significantly reduce the risk of transmission failure. Their studies indicate that vehicles with well-maintained transmission fluids can experience a 30-50% longer lifespan compared to those that do not adhere to maintenance schedules.

Additionally, a study published by the Society of Automotive Engineers (SAE) highlights that maintaining clean transmission fluid can improve shifting performance and reduce wear on internal components. This reinforces the importance of regular fluid changes, whether partial or full.

In summary, understanding the change interval for your Highlander’s transmission fluid and the benefits of partial changes can help you make informed decisions about your vehicle’s maintenance. Regular attention to your transmission fluid will contribute to a smoother, more reliable driving experience.
