5 Signs of Contaminated Transmission Fluid

Everett Transmission & Auto Repair • 10 October 2024

Your vehicle's transmission fluid plays a critical role in ensuring smooth gear shifts, preventing overheating, and keeping internal components lubricated. When this fluid becomes contaminated, it can lead to a range of transmission issues. Keeping an eye out for signs of contaminated transmission fluid can save you from costly repairs. At Everett Transmission & Auto Repair, we can expertly handle problems related to transmission fluid. Here are five signs that your transmission fluid is contaminated.


Dark or Dirty Fluid

Transmission fluid should typically be a bright red color. But as the fluid collects contaminants, it can become dark brown to black. This discoloration indicates that the fluid is no longer effectively lubricating and protecting the transmission components. If you notice your fluid has turned dark or murky, it's time for replacement.


Burnt Smell

If you detect a burnt smell coming from the fluid, this is a warning sign. The smell could be a result of overheating, which breaks down the fluid's protective properties. Burnt fluid not only reduces your transmission's performance, but also increases the risk of serious damage.


Slipping Gears

If your vehicle is having trouble staying in gear or slipping between gears, contaminated transmission fluid could be the culprit. When fluid becomes dirty or filled with debris, it can't generate the proper hydraulic pressure needed for smooth gear engagement. This can cause the transmission to slip, resulting in unpredictable gear shifts.


Delayed or Harsh Shifting

Contaminated transmission fluid can cause delayed or rough shifting. If you experience hesitation when your vehicle shifts gears or notice a hard or jerky motion during shifting, this could be due to debris affecting the fluid's ability to circulate smoothly. Clean, well-maintained transmission fluid is crucial for seamless gear changes.


Unusual Noises

If you hear grinding, whining, or clunking noises when your transmission is shifting gears, contaminated fluid could be to blame. These noises often indicate that debris in the fluid is making it difficult for components to operate properly. Ignoring these sounds could lead to severe transmission damage, so it's essential to address the issue promptly.
