1. Prepare a supply of fresh transmission oil of the required grade (see Specifications).
2. Other tools and materials needed include: jack stands to secure the vehicle in a raised position, a 3/8-inch ratchet (with extension cord) to the socket wrench, a drain container with a capacity of at least 2.5 liters and a supply of rags and/or old newspapers.
3. The oil should be drained after being warmed up to normal operating temperature during a short trip. Hot oil has a higher fluidity and better washes out sludge and other deposits. After making a short trip and warming up the gearbox to normal operating temperature, park the car on a flat horizontal area with a hard surface, jack it up and place it on supports, ensuring free access to the drain plug of the crankcase. Unscrew the plug (see accompanying illustration) and drain the oil into the prepared drain container. 4. Screw the plug back in place and tighten it securely.
5. Pour the required amount of fresh transmission oil of the required grade into the manual transmission housing. The level can be considered normalized when the oil starts to flow out over the edge of the filler hole.
6. Lower the car to the ground.
