Transmission fluid plays a vital role in keeping your vehicle’s transmission system running smoothly. It lubricates moving parts, provides hydraulic power, and helps cool the system. However, when transmission fluid becomes contaminated, it can lead to serious problems. Recognizing the warning signs of contaminated fluid can help you address the issue before costly repairs become necessary. At Lodi Transmissions, our local mechanics can expertly handle issues with transmission fluid. Here’s a look at four warning signs that your transmission fluid is contaminated.

Discolored Fluid

Healthy transmission fluid is typically bright red. If the fluid appears dark brown, black, or has a cloudy appearance, it may be contaminated with debris, burnt particles, or metal shavings. Discolored fluid is a strong indicator that the transmission system needs attention, and replacing the fluid is likely necessary.

Sluggish or Jerky Shifting

Contaminated transmission fluid can disrupt the proper functioning of your vehicle’s gears. You might experience delayed or jerky gear shifts. These issues can stem from degraded fluid failing to provide adequate lubrication and pressure in the system.

Transmission Overheating

The cooling properties of transmission fluid are essential to prevent the system from overheating. When the fluid is contaminated or degraded, it loses its ability to dissipate heat effectively. This can lead to overheating, which is often accompanied by a burning smell. Overheating is a serious issue that can cause extensive damage to your transmission if not addressed promptly.

Noisy Operation

Unusual noises—such as grinding, whining, or clunking sounds—can indicate contaminated transmission fluid. These noises often occur because the fluid is no longer able to properly lubricate the moving parts of the transmission, leading to increased friction and wear. Ignoring these sounds may eventually result in severe transmission damage.
