Your car’s transmission is a complex system that relies on transmission fluid to function properly. This fluid lubricates the gears, helps to cool the system, and prevents wear and tear. Over time, transmission fluid can break down and become contaminated, leading to transmission problems. If you notice any of the following signs, it’s time to check your transmission fluid level and consider a fluid change.
1. Slipping or Jerking Transmission
One of the most common signs of low or contaminated transmission fluid is a slipping or jerking transmission. This occurs when the transmission fluid is not able to lubricate the gears properly, causing them to slip or bind. You may notice that your car hesitates when you accelerate, or that it shifts gears roughly or unpredictably.
2. Strange Noises from the Transmission
Another sign of transmission problems is strange noises coming from the transmission. You may hear a whining, clunking, or grinding sound when you shift gears. These sounds indicate that the transmission is not functioning properly and that the fluid may need to be replaced.
3. Burning Smell
If you notice a burning smell coming from your car, it could be a sign of overheating transmission fluid. This can happen when the fluid is low or contaminated. Overheating can damage the transmission, so it’s important to address this issue promptly.
4. Transmission Fluid Leak
A leak in your transmission can cause the fluid level to drop, leading to the problems mentioned above. Look for puddles of fluid under your car, especially after parking. If you see a reddish-brown fluid, it’s likely transmission fluid.
5. Check Engine Light
While not always related to transmission fluid, a check engine light can sometimes be triggered by transmission problems. If the light comes on, it’s important to have your car diagnosed by a mechanic to determine the cause.
How to Check Transmission Fluid
To check your transmission fluid level, your car should be running and warmed up. Locate the transmission dipstick, which is usually near the engine. Pull out the dipstick, wipe it clean, and reinsert it. Remove the dipstick again and check the fluid level. It should be between the “Full” and “Add” markings. If the fluid is low, you can add more transmission fluid, but it’s important to use the correct type of fluid for your vehicle.
When to Get a Transmission Fluid Change
Transmission fluid should be changed every 30,000 to 60,000 miles, or according to the manufacturer’s recommendations. However, if you notice any of the signs above, it’s a good idea to have your transmission fluid checked sooner. Early detection and maintenance can help to prevent major transmission problems and keep your car running smoothly.
