Your car’s transmission relies on fluid to keep its components lubricated and running smoothly. When transmission fluid levels drop too low, serious problems can arise, potentially leading to costly repairs. Recognizing the signs of low transmission fluid early can help prevent damage and keep your vehicle performing as it should. At Waterloo Transmissions, we can expertly handle leaks that cause low transmission fluid. Here are five warning signs that your car may be running low on transmission fluid.


Slipping Gears

One of the most noticeable signs of low transmission fluid is gear slippage. If your vehicle struggles to stay in gear or shifts unpredictably, it may not be getting enough hydraulic pressure from the transmission fluid. This can cause the engine to rev without a corresponding increase in speed, making driving both frustrating and unsafe. 


Delayed/Rough Shifting

Low transmission fluid can lead to difficulty when shifting gears. You might notice a hesitation when accelerating or feel a jolt when the transmission changes gears. This happens because the fluid provides the necessary lubrication and pressure for smooth gear transitions. Without enough fluid, the gears struggle to engage properly, leading to rough or delayed shifting. 


Overheating Transmission

Transmission fluid plays a critical role in keeping the system cool by reducing friction and dissipating heat. When fluid levels are too low, the transmission can overheat, leading to a burning smell coming from the engine area. Overheating can cause serious internal damage to the transmission, resulting in expensive repairs.


Unusual Noises

A well-functioning transmission should operate smoothly and quietly. However, when fluid levels are low, you may hear whining, grinding, or clunking noises coming from the transmission. These sounds occur because the metal components inside the transmission are not properly lubricated, leading to increased friction and wear. 


Transmission Fluid Leaks

If you notice a puddle of reddish fluid under your vehicle, it’s a warning sign of a transmission fluid leak. Leaks can occur due to worn-out seals, gaskets, or cracks in the transmission system. Even a small leak can soon lead to low fluid levels, causing major transmission trouble.

Common Warning Signs that Your Transmission Fluid Is Contaminated

By Waterloo Transmissions • January 5, 2026
Transmission fluid plays a vital role in keeping your vehicle shifting smoothly and protecting internal components from excessive heat and wear. Over time, however, transmission fluid can become contaminated by dirt, metal particles, and moisture. When this happens, the fluid loses its ability to properly lubricate and cool the transmission. Recognizing the warning signs of contaminated transmission fluid early can help you avoid serious damage and costly repairs. At Waterloo Transmissions, we can expertly handle issues related to transmission fluid. Here’s a look at four signs that your transmission fluid is contaminated. Dark/Discolored Transmission Fluid Healthy transmission fluid is typically bright red and has a clean appearance. If the fluid appears dark brown, black, or cloudy, contamination is likely present. Discoloration often indicates excessive heat, debris buildup, or fluid breakdown. Checking the fluid color regularly can provide an early warning that your transmission needs service. Burnt Odor A strong burnt smell coming from the transmission fluid is another common sign of contamination. This odor usually means the fluid has been overheated and is no longer protecting internal components effectively. Burnt fluid can lead to increased friction, accelerated wear, and potential failure if it isn’t addressed promptly. Delayed/Rough Shifting Contaminated transmission fluid can interfere with proper hydraulic pressure inside the transmission. As a result, you may notice delayed engagement when shifting into gear or rough, jerky shifts while driving. These symptoms indicate that the fluid is no longer providing the smooth lubrication and pressure needed for precise gear changes. Slipping Gears or Loss of Power When transmission fluid is contaminated, it may not maintain consistent pressure, causing gears to slip unexpectedly. You might feel the engine rev without a corresponding increase in speed or experience a sudden loss of power while driving. Gear slipping is a serious warning sign that should be inspected immediately to prevent further damage.

4 Common Warning Signs of a Transmission Issue

By Waterloo Transmissions • December 6, 2025
Your vehicle’s transmission plays a crucial role in keeping your car moving smoothly, and when something goes wrong, the symptoms often start small before becoming serious. Recognizing early warning signs can help you avoid costlier repairs. At Waterloo Transmissions, we can expertly diagnose and repair transmission problems. Here are four common signs that your transmission is in trouble. Unusual Noises While Shifting One of the first signs of transmission trouble often comes in the form of strange noises. If you start hearing grinding, whining, or clunking when your vehicle shifts gears, it may indicate worn internal components or low transmission fluid. These noises can happen during acceleration, deceleration, or even when the car is in neutral. Even if the sounds seem mild, they signal that something isn’t operating correctly. Ignoring these noises can lead to more severe internal damage, so it’s best to have them checked promptly. Slipping Gears While Driving A slipping transmission can be both frustrating and dangerous. If your vehicle seems to change gears unexpectedly or has trouble staying in gear, it’s a clear sign something is wrong. You may notice the engine revving higher than usual without a corresponding increase in speed, or the car may feel like it jolts in and out of gear. This type of issue often points to low fluid levels or internal wear. Because slipping can affect your ability to accelerate or maintain speed, it’s important to address this warning sign right away. Delayed or Rough Gear Engagement When you shift from park to drive or reverse, the transition should feel smooth and immediate. If there’s a noticeable delay or rough jump when engaging gears, your transmission may be struggling to circulate fluid or build enough pressure. This problem can stem from a failing pump, contaminated transmission fluid, or internal damage. Any delay or harsh engagement is a sign that your transmission is no longer operating efficiently and needs professional attention. Leaking Transmission Fluid If you spot reddish to brownish fluid under your vehicle, you may be dealing with a transmission fluid leak. This fluid is essential for cooling, lubricating, and powering your transmission. A leak can quickly lead to low fluid levels, which can cause severe internal damage if not corrected. Leaks often come from damaged seals, gaskets, or lines, and they should always be treated as urgent.
