How Often Should the Transmission Fluid in a Manual Transmission Car Be Replaced?
2 Answers
The transmission fluid in a manual transmission car should be replaced approximately every 40,000 to 60,000 kilometers. The method for replacing the transmission fluid is as follows: 1. Draining the fluid: After lifting the vehicle, unscrew the drain plug and the fill plug at the bottom of the transmission. Start the engine, engage first gear, and let the old fluid drain out at idle speed. Use a clean towel to block the high-pressure air pump and blow air into the fill hole to ensure all the old fluid is completely drained. 2. Cleaning: Remove the drain plug and use the high-pressure air pump to blow out any metal particles until they are completely removed. 3. Refilling: Open the front hood, insert a hose from the engine compartment into the fill hole, and add new fluid until it is full. Then, tighten the fill plug. The purpose of transmission fluid is to ensure the normal operation of the transmission and extend the lifespan of the transmission components.
I've been driving this manual transmission car for nearly a decade. Generally, the transmission fluid needs to be changed every 50,000 to 60,000 kilometers, depending on the vehicle model and driving habits. I remember that long trip back to my hometown when I forgot to check the fluid – by 70,000 km the gear shifting became rough with annoying grinding noises. At the repair shop, the mechanic showed me the pitch-black fluid and warned that further delay could damage the transmission. Now I strictly follow the manual's recommendation – my Volkswagen gets fresh fluid every 60,000 km. I also avoid aggressive driving like high-RPM gear changes to prolong its lifespan. After changing to new fluid, the car shifts noticeably smoother and quieter, even at highway speeds.
