How to Tell When You Need a Transmission Fluid Flush

How to Tell When You Need a Transmission Fluid FlushThe general recommendation is that transmission fluid should be flushed every two years or 30,000 miles. However, there are certain symptoms that suggest you need a transmission flush, regardless of how long it's been since you last got one. By keeping up on transmission maintenance, you'll help to prevent problems from arising in the first place. And when considering how expensive transmission repairs can be, you'll definitely want to be proactive about keeping your transmission healthy. Here's a look at five signs that you need a transmission flush.

Issues with Shifting Gears

If your transmission is dirty, then gears may shift too fast or too slowly. For both manual and automatic transmissions, you'll help to ensure smooth shifting by always driving with the right amount of clean fluid.

Slipping Gears

Gunked-up transmission fluid can cause a decrease in hydraulic power to the extent that there might not be sufficient pressure to remain in gear. This could be happening because contaminants are blocking the flow of fluid.


If you put your vehicle in gear and then it momentarily stalls, then it'll likely be worthwhile to get a transmission flush.


Pollutants in transmission fluid are liable to block the fluid's flow. When this flow is obstructed, the vehicle could start lunging or surging. By getting a transmission flush, there's a good chance that this symptom will be remedied.


If you hear grinding noises that are coming from your transmission, then you'll want to safely pull off the road and check your transmission fluid with your car still running. Healthy transmission fluid should have a reddish color. If the fluid looks particularly dark, or if its level is low, then a transmission flush could be beneficial.
