Transmission fluid plays a vital role in keeping your vehicle’s transmission running smoothly by lubricating moving parts, cooling the transmission, and enabling smooth gear shifts. But as it gets older, transmission fluid can become contaminated with dirt, metal particles, and other debris, which can lead to serious problems if left unaddressed. At Express Oil Change & Tire Engineers, we provide top-quality transmission service in Orlando, and our local mechanics can expertly handle issues with transmission fluid. Here are four signs that your transmission fluid may be contaminated.

Discolored Transmission Fluid

Healthy transmission fluid is typically bright red or pink in color. If the fluid appears dark brown or black, it is likely contaminated with dirt, debris, or metal shavings from the transmission components. This discoloration is a clear sign that the fluid has deteriorated and is no longer providing proper lubrication and cooling. A transmission fluid exchange is necessary to restore the fluid’s effectiveness and protect your transmission from damage.

Burnt Odor

Transmission fluid should have a slightly sweet or odorless smell. If you notice a burning or foul odor coming from the fluid, it’s a strong indication that the fluid is contaminated or has become overheated. Burnt fluid loses its ability to properly lubricate the transmission, leading to increased friction, heat, and wear on internal parts. In this case, replacing the fluid is crucial to prevent further issues.

Delayed Gear Engagement

Contaminated transmission fluid can cause delayed or hesitant gear engagement when shifting from park to drive or reverse. If you experience a noticeable delay before your car moves after shifting gears, it could be due to contaminated transmission fluid that is no longer performing as it should.

Unusual Transmission Noises

Unusual noises like whining, clunking, or humming coming from the transmission can also indicate contaminated fluid. Debris or metal particles in the fluid can cause increased friction between internal components, leading to abnormal sounds. These noises are often a sign that your transmission fluid is contaminated and needs to be replaced before further damage occurs.
