Transmission fluid plays an important role in keeping your vehicle's transmission operating smoothly. It lubricates internal components, helps control operating temperatures, and provides the hydraulic pressure necessary for proper gear changes. Over time, however, transmission fluid can become contaminated with dirt, debris, moisture, and worn friction material. Contaminated fluid can reduce transmission performance and contribute to premature wear. At Everett Transmission & Auto Repair, we can expertly address problems related to transmission fluid. Here are four warning signs that your transmission fluid may be contaminated. Dark or Discolored Fluid Fresh transmission fluid is typically bright red or another color specified by the vehicle manufacturer. As fluid ages or becomes contaminated, it can significantly darken. Dark fluid doesn't automatically mean the transmission is failing, but it is a reason to have the fluid professionally inspected, particularly if the color change is accompanied by other symptoms. Unusual Transmission Odor Transmission fluid that has become overheated or contaminated may develop a strong, burnt smell. This can occur when excessive heat breaks down the fluid's protective properties or when internal friction increases. A noticeable burning odor coming from your vehicle should not be ignored because continued operation under these conditions may accelerate transmission wear. Rough or Delayed Shifting Contaminated transmission fluid can interfere with the transmission's ability to maintain proper hydraulic pressure and lubricate moving components. As a result, you may notice harsh gear changes, delayed engagement, or difficulty shifting. If your vehicle suddenly begins shifting differently than normal, the fluid and transmission should be inspected. Slipping Gears Transmission slipping occurs when the transmission fails to remain properly engaged in a selected gear. You may notice the engine revving without a corresponding increase in vehicle speed or feel the transmission unexpectedly change gears. Contaminated fluid can contribute to slipping, although other issues can cause similar symptoms.
