How Often Should You Change Your Transmission Fluid?

There's no one-size-fits-all answer when it comes to how often you should change your vehicle's transmission fluid. In general, adhere to the manufacturer guidelines to ensure that your ride's transmission fluid and filter maintenance is on point and that your car, truck, SUV, or van operates and performs at its peak.

What is a Transmission Fluid Change?

A transmission fluid change involves draining the old transmission fluid from the transmission pan, replacing 30 to 40 percent of the fluid, and installing a new transmission filter. It's recommended for routine maintenance to keep the transmission functioning smoothly.

A transmission fluid change is not the same thing as a transmission fluid flush, which is more time-consuming and typically pricier. A flush, as the name suggests, involves completely flushing out all the old transmission fluid from the system. Special transmission flush fluid is circulated into the transmission system, cleaning out any residue or contaminants. A flush replaces nearly 100 percent of the old fluid. Both procedures can help maintain the health of your transmission, preserve its performance, and prolong its lifespan.

It's always best to consult your vehicle's manual or reach out to the auto techs at your local Toyota dealership for specific recommendations for your car.

How Often Should Transmission Fluid Be Changed?

When it comes to changing transmission fluid, it's essential to follow the manufacturer's recommendations outlined in your vehicle's owner's manual. Some newer vehicles with "lifetime" transmission fluid require less-frequent transmission fluid changes unless a problem with the transmission crops up, necessitating it.

However, some conditions may warrant shorter transmission fluid change intervals such as: towing or hauling, frequent exposure to severe weather conditions, stop-and-go traffic, or at the first sign of transmission problems, such as gear slippage, grinding noises, delayed shifting, and excessive vibration.

Manual transmissions typically require less frequent fluid changes compared to automatic transmissions. Defer to the recommendations of your owner's manual or the service technician at your local Toyota dealership.

How to Check Transmission Fluid?

It's essential to consult your vehicle's owner's manual for specific instructions and recommendations regarding transmission fluid type and level-checking procedures, as they can vary between different vehicles. If you're unsure or uncomfortable performing this task yourself, it's always best to seek assistance from a skilled technician.

In general, to check your transmission fluid, park your car on a level surface and start the engine. Locate the transmission dipstick under the hood, pull it out, and wipe it clean. Fully reinsert the dipstick, then pull it out again to check the fluid level to see where it falls between the markings on the dipstick.

Next, check the color of the transmission fluid: pinkish-red transmission fluid typically indicates that the fluid is clean and healthy with the chemical composition to effectively lubricate and cool the transmission components. If the fluid appears significantly darker or has a burnt smell, it may indicate contamination or degradation, suggesting it's time for a fluid change or closer inspection by a technician.

Most newer model vehicles have sealed transmission systems which may not have a dipstick for checking transmission fluid levels. Instead, the vehicle's internal mechanisms may automatically check and adjust fluid levels. Sealed transmission systems are designed to be maintenance-free. However, if you suspect a problem with a sealed transmission, it's best to consult an auto technician at your local Toyota dealership.

How to Change Transmission Fluid

Changing transmission fluid involves locating the transmission fluid drain plug, draining the old fluid into a container, and removing the transmission pan to access the filter. Final steps include cleaning the pan, reinstalling it, and refilling the transmission with the appropriate type and amount of new fluid, following manufacturer recommendations, and then checking for leaks.

Ultimately, regular maintenance and staying attentive to your vehicle's performance are helpful in determining when transmission fluid changes may be needed. If in doubt, consult the professionals at your local Toyota dealership for personalized advice based on your vehicle's specific needs and usage.
