Is my transmission fluid contaminated? Here are 5 warning signs

Elite Transmissions • 13 October 2024

Transmission fluid plays a crucial role in keeping your vehicle’s transmission system running smoothly. It lubricates the gears, prevents overheating, and helps transfer power from the engine to the wheels. When transmission fluid becomes contaminated, it can lead to various problems. At Elite Transmissions, we can expertly handle issues with transmission fluid. Here are five warning signs that your transmission fluid is contaminated.


Discolored Transmission Fluid

Fresh transmission fluid typically has a bright red or pink color. If the fluid appears dark brown, black, or cloudy, it’s a strong indication of contamination. As the miles add up, transmission fluid can become mixed with debris, leading to a change in color. When you check the fluid and notice a significant discoloration, it’s time to get your transmission system inspected and the fluid replaced.


Burning Smell

A burning odor is a clear sign that something is wrong with your transmission fluid. This smell often occurs when the fluid has become overheated or contaminated with debris. Contaminated fluid loses its ability to lubricate effectively, causing increased friction and heat within the transmission system. If you detect a burning smell, it’s important to have the transmission fluid checked to prevent further damage.


Slipping Gears

One of the most noticeable symptoms of contaminated transmission fluid is gear slippage. If your vehicle struggles to stay in gear or shifts gears unexpectedly, it may be due to dirty or degraded fluid. Contaminated fluid can’t create the proper hydraulic pressure needed to keep the transmission working efficiently, leading to gear slippage and poor performance. 


Unusual Noises

Transmission fluid is designed to lubricate the gears and reduce friction. When the fluid is contaminated, it loses its lubricating properties, which can cause grinding, whining, or clunking noises as the transmission shifts gears. Addressing this issue promptly can help prevent more expensive repairs.


Delayed or Rough Shifting

If your vehicle hesitates or feels rough when shifting between gears, contaminated transmission fluid could be the culprit. When contaminants build up in the fluid, it hinders the transmission’s ability to shift smoothly.
