How Often Should You Change Transmission Fluid: A Guide

Mark Kennedy • July 2, 2024

Knowing how often to change the transmission fluid is crucial to keeping your vehicle in good condition and running smoothly. Professional Automotive Repair in Marietta provides excellent transmission services and guidance on maintaining a highly functioning transmission.


Automatic vs. Manual Transmission Fluid Needs

The type of transmission in your car affects how often you should change the fluid. Automatic and manual transmissions operate differently, so their maintenance schedules are also different.


How Often Should You Change Transmission Fluid

Automatic Transmission Fluid


Automatic transmission fluid, often called ATF, is a type of fluid that works as both a hydraulic fluid and coolant. It is used in vehicles with an automatic transmission system to ensure the gears shift smoothly and keep everything cool. This fluid also acts as a lubricant for the gears inside your car's transmission and it has many important tasks. Car manufacturers typically recommend changing the automatic transmission fluid between 60,000 and 100,000 miles. However, if you drive frequently in heavy traffic or tow heavy loads, it may be necessary to replace this fluid more often.

In Professional Automotive Repair, we fill the transmission with superior-quality automatic fluid. This fluid meets or surpasses the standard set by your vehicle's manufacturer. It aids in maintaining smooth shifting actions and overall good performance of your transmission system.


Manual Transmission Fluid


Fluid for manual transmission, also called gear oil, is thicker and acts stronger against heat. The change time can be extended for manual transmissions, with many manufacturers proposing it should occur every 30k to 60k miles. This duration could lessen because of tougher driving situations like automatic transmissions.

At our Marietta shop, we provide exceptional service for both automatic and manual transmissions. We also choose the right type and quality of fluid for your vehicle.


The Recommended Transmission Fluid Change Intervals


What type of transmission you possess, either automatic or manual, will impact the usual timings for fluid changes. However, it is crucial to adhere to what your vehicle manufacturer suggests - these are some common recommendations:

  • Automatic Transmissions: Exchange between 60,000 and 100,000 miles. However, if you drive in tough situations, think about doing it sooner.
  • Manual Transmissions: Typically, they require fluid changes every 30k-60k miles, depending on usage and manufacturer recommendation.

The team from Professional Automotive Repair in Marietta can review your car's manual and examine its transmission, making a suggestion tailored to you.


Factors Affecting Your Transmission Fluid Change Schedule


Several factors can influence your transmission fluid change schedule, including:

  • Driving Conditions: Driving in the city with frequent stops and starts, hauling heavy loads, or driving on steep hills can accelerate the deterioration of transmission fluid.
  • Type of Transmission: Automatic transmissions generally need fluid changes more frequently than manual ones. This is due to their complexity and the heat they generate.
  • Vehicle Age: Older vehicles might require more frequent fluid changes because components wear down and the liquid loses its potency.
  • Professional Automotive Repair considers these elements, using advanced diagnostic tools and our extensive knowledge to improve the timing of your car's transmission fluid change.


The Importance of Regular Transmission Fluid Change


Regular transmission fluid changes are essential for several reasons:

  • Avoid Damage to Transmission: Clean fluid aids in lubricating your transmission components and maintains their coolness, which prevents premature wear out and potential failures.
  • Maintain Performance: Fresh fluid ensures smooth shifting and optimal performance from your vehicle.
  • Prevent Big Repairs: Regular changes can help prevent the need for more significant and expensive repairs in the future, as they help detect problems early on.
