Transmission fluid is a type of oil that lubricates and cools the moving parts of your car’s transmission system. It is crucial to maintain the right amount of fluid in your vehicle’s transmission, as too much or too little can have serious consequences on the car’s performance and longevity.
II. 5 Warning Signs of Overfilled Transmission Fluid in Your Car
Here are the five most common symptoms of an overfilled transmission fluid:
The dipstick reading is the first warning sign that your car’s transmission may have too much fluid. If the level is higher than the “full” mark, then you have too much transmission fluid in your car.
If the transmission fluid starts to burn, it gives off an unpleasant odor. This usually happens because the fluid is overheating, and it can cause severe damage to the transmission.
Leaking Transmission Fluid
If there is an excessive amount of fluid in the transmission, it can cause the seals to break, resulting in leakage of the fluid. If you notice puddles of the fluid under your car, it is a clear indication of a leak.
Difficulty Shifting Gears
If you experience difficulty in changing gears or the gears slip, it could be because of the overfilled transmission fluid. The transmission may fail to shift gears correctly, affecting the car’s overall performance.
An overfilled transmission can cause fluid foaming, resulting in increased transmission temperature. When the temperature reaches a certain level, the transmission system may stop functioning entirely.
III. How Excess Transmission Fluid Can Damage Your Vehicle: Symptoms and Solutions
Here are some of the reasons why excess transmission fluid can damage your car, along with solutions:
Damage to Transmission Seals
Too much transmission fluid can cause high pressure on the seals, leading to their breakage. This damage leads to leakage and other severe complications, including transmission failure. Solution: Have a professional drain the excess fluid and replace damaged parts.
Increased Pressure on Transmission Components
The excessive fluid can cause the system to operate at higher pressure than the manufacturer intended. The increased stress on the components of the transmission can cause premature wear and eventual failure. Solution: Have the excess fluid drained, and check for any damaged parts.
Foaming of Transmission Fluid
Excess fluid can cause aeration and introduce air bubbles into the transmission fluid, which can cause foaming. The problem with aeration is twofold: First, the air bubbles don’t provide adequate lubrication, which causes friction and leads to severe wear and tear of the transmission’s moving parts. Second, the air bubbles increase the pressure, which can cause the seals to break, resulting in fluid leakage. Solution: Have an expert remove the extra fluid and flushed the system to remove remaining foam.
IV. Don’t Ignore These 4 Symptoms of Overfilled Transmission Fluid
Ignoring these symptoms can lead to irreversible damage to your car. Here are the symptoms to watch out for:
If you notice that the gears are slipping, it is a sign of overfilled transmission fluid. Overfilled transmission fluid causes erratic changes of the gears, resulting in slipping to the next lower gear or sometimes into the next higher gear.
An overfilled transmission will start to produce a whining, buzzing, or humming noise. The noise worsens as you drive, indicating that there is an issue with the transmission system.
If there is a delay in the car engaging when you shift into gear, it could be due to overfilled transmission fluid. The delay in shifting gears is a clear indication that the transmission fluid needs to be checked immediately.
Check Engine Light
Finally, the overfilled transmission fluid can turn on the check engine light. The light comes on to signal a problem with your car, and you should take your car for professional service immediately.
V. Transmission Fluid Leaking or Overfilled? Here are the Symptoms to Watch Out For
Here are some of the signs that your car is either leaking or overfilled with transmission fluid:
Puddles of Transmission Fluid Under the Car
You should be able to spot the transmission fluid under your car if the amount is high enough to form puddles. If you notice reddish-brown fluid under your car, it is a clear sign that there is a leak in the transmission system.
Low Transmission Fluid Levels
If you consistently top up your transmission fluid, it may indicate that there is a leak in the system. Low transmission fluid levels also mean that the remaining oil is overused and broken beyond repair.
If there is a slippage in the gear performance, it could also indicate that the fluid is running low.
The delayed engagement of the gear is another sign that all is not right with the transmission system. The chances of the problem being the transmission fluid are high.
VI. Is Your Car Acting Weird? Check for These Symptoms of Too Much Transmission Fluid
Here are some of the additional symptoms that you can observe:
Dragging Sensation While Driving
An overfilled transmission fluid will cause the car to drag while driving. The sensation feels as though the handbrake remains engaged, even though it is off.
Burning Smell from Under the Hood
A burning smell comes from excess transmission fluid burning. You can recognize it quickly because it is a foul odor that is unmistakable.
Difficulty in Changing Gears
If the gear is difficult to change, it could be one of the initial signs of low fluid levels. However, it is also a sign of excess fluid levels that cause the gears to be unresponsive to transmission fluid cues.
Reduced Speed and Acceleration
Damaged and overfilled transmission fluid can cause erratic performance issues in your car, which lowers the vehicle’s overall speed and acceleration.
Regularly checking your car’s transmission fluid levels is crucial if you want to avoid future repair expenses. We have identified several symptoms of overfilled transmission fluid that should raise a red flag for you. We emphasize the importance of monitoring your vehicle’s performance, immediately seeking professional help if you notice any of these symptoms.
Remember, timely intervention can save you a lot of expenses and extend the lifespan of your car.
