What are the symptoms of overfilling transmission fluid?
2 Answers
The symptoms of overfilling transmission fluid are: 1. Poor lubrication of the transmission, leading to reduced lifespan; 2. Transmission slippage and gear shift impact; 3. Severe damage or even complete failure of the transmission. Precautions for changing transmission fluid: 1. Choose the appropriate viscosity when changing the fluid to avoid power loss; 2. Use qualified transmission fluid; 3. Be careful not to introduce impurities when changing the transmission fluid. Transmission maintenance methods: 1. Regularly check the fluid level; 2. Do not skip gears when upshifting; 3. Do not force the transmission into neutral; 4. Do not shorten the idle warm-up time; 5. Avoid gear grinding when shifting. The functions of the transmission are: 1. Changing the transmission ratio; 2. Expanding the torque and speed of the driving wheels; 3. Enabling the vehicle to reverse; 4. Facilitating gear shifting or power output.
I once encountered an issue with overfilling transmission fluid in my old car when I did a DIY fluid change and mis-measured the amount. The car felt off afterward. Shortly after starting, there was a noticeable oil smell, and gear shifts became rough with frequent slight jerks, especially at low speeds. To make matters worse, oil started leaking from underneath—inspection revealed the seals were deformed from excessive pressure, causing fluid to drip onto the ground. This is easily overlooked, but if not addressed promptly, it can lead to transmission overheating or even component damage. Since then, I check the fluid level every six months to avoid repeating the mistake. Always measure carefully with the dipstick when refilling—never overfill to save on costly repairs later.
