Does Manual Transmission Fluid Need to Be Changed?
2 Answers
Manual transmission fluid does need to be changed. The replacement method is as follows: 1. Lift the car, loosen the drain screw and fill screw at the bottom of the transmission, start the engine, engage first gear at idle speed to let the old fluid flow out. Use a towel to block the high-pressure air pump, then blow the high-pressure air pump towards the fill hole to completely drain the old fluid. 2. Remove the drain screw and use the high-pressure air pump to blow away all metal particles. 3. Open the hood, insert a hose from the engine compartment into the fill hole to add new fluid. After filling, tighten the fill screw. Transmission fluid is a lubricant that keeps the transmission system clean, ensuring normal operation of the transmission and extending the lifespan of the transmission components.
As a seasoned manual transmission driver, changing the transmission fluid is a must. Over time, transmission fluid oxidizes and thickens, mixing with metal shavings and debris, which affects gear shifting smoothness. I remember once when I neglected to change it, the gear grinding was severe during shifts, costing me thousands in repairs. It's recommended to change it every 30,000 to 50,000 kilometers or every two years, depending on driving habits and vehicle model. Changing the fluid isn't expensive—just a couple hundred at a repair shop—and afterward, it feels as smooth as a new car. Regularly check the fluid color; if it turns black or has a foul odor, that's a warning sign. Developing this habit can extend your transmission's lifespan by over ten years, saving you money and ensuring safety. Don't underestimate this small task, or you'll regret it later.
