What is the method for changing car transmission fluid?
2 Answers
Car transmission fluid replacement method is: 1. Start the engine for preheating; 2. Remove the drain bolt; 3. After the transmission fluid is drained, reinstall the bolt; 4. Locate the transmission fluid filler port and add new fluid; 5. Start the vehicle and perform gear shifting operations, pausing for 5 seconds in each gear; 6. Check whether the transmission fluid level is normal. The functions of the transmission are: 1. To change the transmission ratio and expand the variation range of driving wheel torque and speed, allowing the engine to operate under favorable conditions; 2. To enable the vehicle to reverse while maintaining the engine's rotation direction; 3. To interrupt power transmission using neutral gear, allowing engine starting and idling, facilitating gear shifting or power output.
I once changed the transmission fluid myself and it felt amazing. The whole process can be broken down into steps: First, choose the correct fluid type—manual and automatic transmissions require different fluids. I usually buy from reputable stores to avoid low-quality products. The tools needed include a jack stand, wrench, drain pan, and new transmission fluid. Before changing the oil, warm up the car for a few minutes, park on level ground, get under the car, and loosen the drain plug to let all the old fluid flow into the pan—be careful not to burn yourself. Once it’s completely drained, tighten the drain plug back, then add new fluid from the top of the transmission using a funnel, pouring slowly to avoid spills. Checking the fluid level is crucial—start the car, shift through gears for a few seconds, turn it off, and check the dipstick to ensure it’s at the correct level. The whole process takes about half an hour, and remember to wear gloves to protect your hands. If it’s a CVT transmission, the process is more complex, so beginners should watch tutorials or get help. Regular fluid changes protect the transmission, extend its lifespan, and save money.
