How to Replace Gear Oil?

[VanPaige]

Locate the position of the odometer cable on the transmission, remove the odometer cable shaft cover, and pull out the small gear. Remove the gear oil drain plug of the transmission, drain the old gear oil completely, and tighten the drain plug. Start adding new gear oil from the odometer shaft hole. Reinstall the removed gears according to the operation manual.

Last time I manually changed the gear oil, the steps were actually quite simple, and doing it myself saved a lot of money. First, check your vehicle's manual for the recommended oil type and change interval—usually every 30,000 to 50,000 kilometers. Prepare new gear oil, a wrench, an oil pan, and gloves. Find a level surface, use a jack to lift the car securely, locate the drain plug hole at the bottom of the transmission, and unscrew it to let the old oil flow into the pan—the old oil is black and thick, so make sure it drains completely. Then screw the plug back in, and fill the new oil through the top filler hole, using a funnel to pour it slowly until the overflow hole starts leaking oil, indicating the oil level is full. Finally, check that all screws are tightened, test-run the car to ensure no unusual noises, and you're done. The whole process took me half an hour, using cheap tools bought online for less than 100 yuan, saving more than half compared to going to a shop. Remember to wear gloves to avoid getting dirty, prevent oil from splashing on your skin, and avoid environmental pollution.

As a budget-conscious car owner, changing gear oil is actually a very cost-effective DIY project. I always purchase the right specification oil in advance, choosing a reliable but not overly expensive brand, and just use a basic socket wrench set for tools. Before draining the oil, make sure the car is parked steadily and the jack is sturdy – I once tried saving money with old tools and nearly had a slip-up, thankfully nothing happened. When draining, be patient and let all the old oil flow out completely. When adding new oil, pay attention not to overfill or underfill, checking the oil level with the dipstick or overflow hole. If I'm unsure, I'll refer to video tutorials and follow the steps carefully. The entire cost is kept under a hundred yuan, and I get to learn some automotive knowledge too. Regular oil changes prevent transmission wear and save on long-term repair costs. I now change it every 40,000 kilometers to ensure smooth vehicle operation.

Safety comes first when changing gear oil. As an experienced driver with years of driving, I pay special attention to details. Always use professional stands to support the lifted car, not just relying on the jack to avoid slipping hazards. Wear gloves and goggles to protect against oil stains, and don't discard the old oil carelessly as it is toxic. Open the drain plug hole to release the oil, but don't rush—make sure there's no temperature to prevent burns. When adding new oil, ensure the correct specification is used to avoid mixing with old oil residue and damaging the gears. Throughout the process, I simplify operations in a safe environment, ensuring each step is steady and unhurried.
