What are the indications of contaminated transmission fluid?
Transmission fluid is essential for keeping your vehicle's transmission running smoothly, as it lubricates moving parts, keeps the transmission cool, and enables proper hydraulic pressure. However, if your transmission fluid becomes contaminated, it can lead to significant problems. At Transmission Service Connection, we can expertly handle issues related to transmission fluid. Here are five signs that your transmission fluid may be contaminated.
Discolored Transmission Fluid
Fresh transmission fluid is usually bright red, which indicates it’s in good condition. If your fluid has turned dark brown or even black, it’s a sign of contamination. Discolored fluid will be less effective at lubricating the transmission, which can lead to wear and tear on internal components.
Strange Odors
If your transmission fluid smells burnt, it’s likely contaminated. A burning smell could mean the transmission is overheating or that the fluid has been exposed to extreme heat for an extended period. This can lead to degraded fluid that no longer performs its job effectively. Burnt transmission fluid can also be an early warning sign of friction between parts due to a lack of lubrication.
Transmission Slipping or Hesitating
Contaminated fluid can interfere with the transmission’s ability to shift gears smoothly. If your transmission begins slipping, hesitating, or shifting at the wrong times, it may be struggling due to dirty or contaminated fluid. Contaminants in the fluid can affect hydraulic pressure, causing the transmission to act erratically.
Unusual Noises
Grinding, whining, or clunking noises coming from the transmission can signal that something isn’t right. When transmission fluid is contaminated, it may lose its ability to lubricate internal parts effectively. As a result, metal components inside the transmission can harshly rub against each other, causing these sounds. Addressing contaminated fluid early on can prevent costly repairs due to metal-on-metal contact.
Visible Debris in the Fluid
If you check your transmission fluid and notice small particles, dirt, or metal shavings, it’s a clear sign of contamination. These contaminants can circulate through the transmission system, increasing wear on internal parts. Regularly checking your transmission fluid for debris can help catch issues early and prevent further complications.
