Warning Signs You’re Driving With Contaminated Transmission Fluid
Transmission fluid plays a critical role in keeping your vehicle’s transmission cool, lubricated, and operating smoothly. But as it ages, transmission fluid can become contaminated. When this happens, the transmission’s performance suffers and significant damage can occur if the issue is ignored. At All Pro Transmission & Auto Repair, we can expertly address issues related to transmission fluid. Here are five signs that your transmission fluid is contaminated.
Rough or Delayed Shifting
One of the most common signs of contaminated transmission fluid is rough or delayed gear changes. Dirty or degraded fluid cannot properly lubricate internal components or maintain the hydraulic pressure needed for smooth shifting. As a result, you may feel hard shifts, hesitation when changing gears, or slipping between gears while driving.
Unusual Transmission Noises
A healthy transmission operates quietly. When fluid becomes contaminated, it loses its ability to cushion moving parts, leading to increased friction. This can cause whining, grinding, or humming noises. These sounds often indicate that internal components are wearing faster than they should.
Overheating or Burning Smell
Contaminated transmission fluid is less effective at dissipating heat. As temperatures rise, you may notice a burning smell. Overheating can damage internal parts, making this warning sign one that should never be ignored.
Discolored or Cloudy Fluid
Healthy transmission fluid is typically reddish in color. Contaminated fluid may appear dark brown, black, cloudy, or gritty when checked on the dipstick. This discoloration often indicates the presence of debris/contamination. Any noticeable change in fluid appearance suggests it’s time for service.
Slipping or Loss of Power
When transmission fluid is contaminated, it may not provide the pressure needed to keep gears properly engaged. This can cause the transmission to slip. Slipping reduces power delivery and can make the vehicle feel unreliable or unsafe to drive.
