Early detection can save you money and avoid more, more serious damage to your vehicle, just as it can save you money and prevent further, more serious damage to every other part of your car. Learn to spot the warning signs of transmission trouble and take your car to an auto repair shop as soon as possible if you notice any of them.
Major Signs of Transmission Problems
1. Strange smell
Strange odors abound on road trips, so pay attention if any of them seem to be coming from your car. A burning odor is a sure sign that something isn’t functioning properly. Transmission fluid overheats and begins to burn as it becomes poor or degraded. This causes the engine to overheat, resulting in premature wear, debris, and corrosion. Burning odors may also be caused by stuck plastic, leaking antifreeze, or a melting heater heart. No matter what the source of a burning odor is, you can still get it checked out.
2. Switching gears refusal
If your vehicle refuses to shift gears or fails to do so, you’re most likely dealing with a transmission problem. In this case, low transmission fluid or the wrong kind of transmission fluid is often to blame.
3. Worn clutch
Another common manual transmission issue is a worn clutch. The clutch in a manual transmission system may wear out due to mechanical error, such as a hydraulic fluid leak in the clutch master cylinder, or human error, such as the driver repeatedly accelerating and moving through the gears without releasing the clutch. This can easily wear out a manual transmission clutch, necessitating clutch replacement.
4. Leaking of transmission fluid
A red fluid leak from one of the cooler lines, a gasket, or a seal under the vehicle indicates a transmission fluid leak. Not only is this bad for the transmission, but it can also be harmful if the fluid spills into a hot pipe or other surface. Check the fluid level and condition of your dipstick. Note that not all transmission fluid is red, and not all levels can be checked with a dipstick, necessitating the use of specialized equipment.
5. Neutral noises
Strange noises coming from your car when in neutral are a sure sign of transmission trouble. The noises may indicate that your car needs new transmission oil, or they may indicate that an expensive component replacement is needed due to mechanical wear.
6. Car has no power
If the car has no or limited power when the engine is running normally, it may be due to internal transmission issues, dragging brakes caused by a defective caliper or brake hose, or the vehicle’s computer restricting power to protect the engine due to a problem it has found. To isolate the problem, have the vehicle’s trouble codes tested.
7. Slipping Gears
Typically, a vehicle’s gear changes are based on external feedback. Every gear shift in a manual transmission is made by the driver. When using an automatic transmission, the driver has the option of selecting reverse, neutral, or drive. It’s unsafe for you and harmful to your engine if your car shifts between gears without your input. Gear slipping may be caused by low fluid levels or worn transmission bands.
8. Grinding or Shaking
A grinding or shaking that happens when the gears shift is always a sure sign that your transmission has a problem, and it’s more common in cars with automatic transmissions.
9. Bearings for needle roller failure
Needle bearings are thin, light roller bearings that keep the gears in the torque converter of an automatic transmission from grinding. You can hear grinding or brushing noises coming from your vehicle while it is moving if the transmission needle bearings become worn or sluggish. This noise could indicate that your transmission gears are moving inefficiently and are wearing down prematurely.
If your car doesn’t react when you try to shift gears, particularly from park to drive, it’s most likely due to a transmission problem.
