5 Symptoms of Contaminated Transmission Fluid

North Seattle Transmission • October 10, 2024

Transmission fluid is crucial for the smooth operation of your vehicle’s transmission system. It lubricates the moving parts, cools the transmission, and helps with shifting gears. However, the fluid can become contaminated by dirt and debris, which can lead to performance issues and potential damage. Knowing the signs of contaminated transmission fluid can help you take timely action before serious problems arise. At North Seattle Transmission, we can expertly handle your car’s transmission fluid issues. Here are five signs of contaminated transmission fluid.


Dirty or Dark Fluid

Transmission fluid should be a bright red or pinkish color, and it should appear clean. If you check the transmission dipstick and notice that the fluid has turned dark brown, black, or looks murky, it’s a clear sign that it has become contaminated. This dark fluid often contains dirt, metal shavings, or other debris that can harm your transmission's internal components. 


Burnt Smell

Fresh transmission fluid often has a slightly sweet scent. If you detect a burnt smell when checking the fluid, this could indicate that it has overheated and become contaminated. 


Slipping Gears

Contaminated transmission fluid can affect your vehicle’s ability to shift gears smoothly. If you notice that your vehicle struggles to shift or seems to slip out of gear, it could be due to dirty or degraded fluid. When transmission fluid is contaminated, it loses its ability to maintain the necessary hydraulic pressure, which results in inconsistent gear shifts or slipping. 


Unusual Noises

A well-functioning transmission should operate quietly. However, if the fluid becomes contaminated, you may start to hear strange noises such as grinding, whining, or clunking sounds. These noises often indicate that dirt or debris in the fluid is preventing the transmission’s components from working smoothly.


Delayed or Rough Shifting

When transmission fluid is contaminated, it may struggle to provide the smooth operation your transmission needs. This can result in delayed shifts or rough shifting. If you experience delays when shifting from park to drive or rough shifts while accelerating, it’s possible that contaminated fluid is to blame.

The transmission is a vital component of any vehicle, responsible for transferring power from the engine to the wheels and enabling you to drive smoothly. But as it ages, your transmission may experience significant wear and tear, leading to issues that can become very expensive to address. Recognizing early signs of transmission trouble can help you get timely service and avoid bigger problems. At North Seattle Transmission, we provide expert transmission repair in the greater Shoreline, WA area. Here are five signs of a transmission problem. Grinding or Shaking During Gear Shifts A well-functioning transmission should shift gears smoothly and quietly. If you start feeling grinding or shaking, especially when switching between gears, it could indicate worn-out or broken transmission components. Delayed or Slipping Gears If your vehicle hesitates when you try to accelerate, or if it seems to slip out of gear, this suggests a transmission issue. Gear slipping happens when the transmission shifts unexpectedly, often resulting in a loss of power. This can be caused by low transmission fluid levels or problems with the transmission’s internal mechanisms. Unusual Noises Unusual sounds—like whining, buzzing, or humming—that come from your vehicle’s transmission area may indicate a problem. These sounds can mean that the transmission fluid is low, contaminated, or that there’s a mechanical issue. Strange noises should be brought to the mechanic’s attention ASAP. Fluid Leaks Under the Car Transmission fluid is typically a reddish color and has a slightly sweet smell (unless it’s burnt). If you notice a reddish liquid pooling under your car, it could be a transmission fluid leak. A leak can lead to low fluid levels, causing transmission issues like overheating, slipping gears, and other mechanical problems. Leaks should be fixed promptly to avoid further transmission damage. Burning Smell A burning smell coming from your car could mean the transmission is overheating. Low or dirty transmission fluid is often the cause, as it reduces the fluid’s ability to lubricate and cool the transmission properly. If left unchecked, overheating can cause significant internal damage.

Transmission fluid is necessary for smooth gear shifts and proper lubrication of moving parts. However, when leaks occur, it can lead to serious issues, including transmission failure if left unaddressed. At North Seattle Transmission, we provide expert transmission fluid leak repair in the greater Seattle area. Here’s a look at four common sources of transmission fluid leaks. Damaged Transmission Pan Gasket The transmission pan is responsible for holding the transmission fluid. As the miles add up, the gasket that seals the pan to the transmission can deteriorate or become damaged, leading to leaks. You may notice reddish-colored fluid pooling underneath your vehicle when parked. Inspecting the transmission pan and gasket for signs of wear, such as cracks or visible leaks, can help identify this issue. Worn Input or Output Shaft Seals The input and output shaft seals prevent transmission fluid from leaking where the transmission connects to the engine and driveshafts. Continuous exposure to heat and pressure can cause these seals to degrade, resulting in fluid leaks.
