When to Get Your Transmission Flushed

TransmissionYour vehicle relies very heavily on the functionality of your transmission. Without a working transmission, you wouldn’t be able to get anywhere. That’s why it’s so important to have your transmission serviced regularly. One of these regular maintenance services is a transmission flush, but how often should drivers in Mobile, Prichard, and Saraland flush their transmission?

On this page, we at Nissan of Mobile will go over how often you should get your transmission flushed, common signs that your transmission needs to be flushed, and more. Read ahead to get started!

How Often Should You Flush Your Transmission?


Most owner’s manuals and service technicians will tell you that your transmission needs to be flushed roughly every two years or 30,000 miles. However, this timeline can be thrown off a bit if you frequently tow heavy loads, take your vehicle off-roading, or drive in stop-and-go traffic. These driving conditions can cause the fluid in your transmission to break down quicker than normal, meaning your transmission will need to be flushed sooner than normal.

Signs that You Need a Transmission Flush

Typically, right around the time that your transmission needs to be flushed, it’ll start exhibiting some common signs. You can expect to see them around every 30,000 miles when your regular transmission is due. However, you should keep an eye out for these signs all the time in case your transmission experiences a problem and needs to be looked at sooner…

  • Unusual noises, like grinding, coming from the transmission
  • Transmission slips from gear to gear without you shifting
  • Difficulty or inability to shift out of neutral or from gear to gear
  • Surging forward while you’re driving
  • The feeling of falling backward while you’re driving
  • Delayed response from the transmission when you shift.

These are some of the most common signs that your transmission fluid needs to be flushed. However, sometimes you won’t experience symptoms at all, which is why regular transmission inspections are vital.

What Does a Transmission Flush Actually Do?

Transmission Fluid

By definition, a transmission flush is a preventive service that cleans out the transmission. Grime, sludge, and other types of debris can build up throughout your transmission, which can make it difficult for the transmission to do its job.

On top of cleaning the transmission, a transmission flush also involves replacing the old oil in the transmission with new oil. Draining the old oil from the transmission is actually the first step in the transmission flush process. Once it’s all out, new oil and likely some cleaning solution will be put back in and will be run through the transmission to clean it and tune it up in the process.
