How to Change Manual Transmission Fluid?
2 Answers
Manual transmission fluid can be changed using the following methods: 1. Gravity Drain Method: Loosen the oil pan bolt to allow the transmission fluid to drain out by gravity; 2. Machine Flush Method: Store new transmission fluid inside a flushing machine, connect the transmission to the machine via hoses, and use the machine to push out the old fluid with the new one. A manual transmission is a gearbox that alters the engine's speed and torque delivered to the drive wheels. It enables the vehicle to achieve varying traction and speed during scenarios like stationary starts, hill climbs, turns, and acceleration, while keeping the engine operating within its optimal performance range.
I've changed the manual transmission fluid myself a few times, and the process isn't too difficult. First, start the car and let it run for a few minutes to warm up the fluid for better flow, making it easier to drain. After parking, find a level surface, use a jack to lift the car, but safety is paramount—always use support stands to prevent collapse. Crawl under the car to locate the transmission's bottom, usually there's a drain plug; use a wrench to loosen it, place a large container underneath to catch the old fluid. Once drained, wipe clean and screw it back. The fill hole is on the side of the transmission; use a funnel to slowly pour in new fluid—I chose GL-4 specification, and don't exceed the recommended amount. After filling, start the car and cycle through all gears, then turn off the engine and check the fluid level again to ensure it's between the min-max marks on the dipstick. Essential tools include a jack, wrench, funnel, and oil pan. Changing it every 30,000 kilometers or two years helps reduce wear. Don't dispose of old fluid improperly—recycle it to protect the environment and extend your car's lifespan.
