Recommended Change Interval

For the 2018 Acura TLX, the manufacturer generally recommends changing the transmission fluid every 60,000 to 90,000 miles (approximately 96,000 to 144,000 kilometers ). This interval can vary based on driving conditions, so it’s essential to consider your driving habits.

Factors Influencing Change Intervals

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

  • Driving Conditions: Frequent stop-and-go traffic, towing, or driving in extreme temperatures can accelerate fluid degradation.
  • Driving Style: Aggressive driving can put additional strain on the transmission, leading to faster fluid breakdown.
  • Fluid Quality: Using high-quality transmission fluid can extend the life of the fluid, while lower-quality options may require more frequent changes.

Partial Transmission Oil Changes

In many cases, a full transmission fluid change is not feasible without removing the transmission from the vehicle. Instead, many owners opt for partial transmission fluid changes, which can help maintain fluid quality without the need for a complete overhaul.

What is a Partial Transmission Fluid Change?

A partial transmission fluid change involves draining a portion of the old fluid and replacing it with new fluid. This method is often more accessible and can be performed without extensive labor.

Benefits of Partial Changes

Here are some advantages of opting for partial transmission fluid changes:


  1. Cost-Effective: Partial changes are generally less expensive than full fluid changes, making them more accessible for regular maintenance.

  2. Less Downtime: Since partial changes require less time, you can get back on the road faster.

  3. Improved Fluid Quality: Regular partial changes can help maintain better fluid quality, reducing the risk of transmission issues.

Statistical Support for Partial Changes

According to the Automatic Transmission Service Group (ATSG), regular maintenance, including partial fluid changes, can significantly extend the life of your transmission. Studies indicate that vehicles with well-maintained transmission fluid experience fewer failures and repairs. In fact, a report from the National Highway Traffic Safety Administration (NHTSA) suggests that proper fluid maintenance can reduce the likelihood of transmission-related issues by up to 50%.

How to Perform a Partial Change

If you decide to go the route of a partial transmission fluid change, here’s a basic outline of the process:

  • Drain the Fluid: Remove the transmission pan or drain plug to let out a portion of the old fluid.
  • Replace the Filter: If applicable, replace the transmission filter to ensure clean fluid circulation.
  • Add New Fluid: Refill with the recommended transmission fluid, ensuring you do not overfill.

Regularly changing your transmission fluid, whether fully or partially, is crucial for the longevity and performance of your Acura TLX. Keeping an eye on your change intervals and understanding the benefits of partial changes can help you maintain your vehicle effectively.
