What are the effects of overfilling transmission fluid in a car?
2 Answers
Overfilling transmission fluid in a car can have the following effects: 1. Increased oil pressure; 2. Higher risk of oil seal leakage; 3. Increased resistance in internal gears. Maintenance methods for the transmission include: 1. Regularly changing the transmission fluid; 2. Frequently checking the fluid level; 3. Avoiding coasting in neutral; 4. Periodically cleaning the transmission; 5. Avoiding forced gear disengagement; 6. Reducing the time spent idling to warm up the engine. The functions of the transmission are: 1. Changing the transmission ratio to expand the range of torque and speed variation of the driving wheels, adapting to frequently changing driving conditions and allowing the engine to operate under favorable conditions; 2. Enabling the car to reverse while maintaining the engine's rotation direction; 3. Using neutral to interrupt power transmission, allowing the engine to start, idle, and facilitating gear shifting or power output.
I once made the mistake of overfilling transmission fluid. Back when I got my new car, I tried saving money by refilling it myself but poured too much without checking the manual. Problems surfaced on the road: gear shifts became sluggish with delays, sometimes accompanied by grinding noises, and the temperature kept rising alarmingly. Later I learned excess fluid increases internal pressure, causing foam that impairs lubrication and risks overheating or leaks. Prolonged use could severely wear transmission components, leading to costly repairs. Now I always check the dipstick on a cold engine to ensure proper levels during fluid changes. Maintenance is crucial—no cutting corners. When in doubt, it's best to visit a professional shop.
