2. Prepare a supply of fresh transmission oil of the required grade (see Specifications), a drain container of suitable capacity, a wrench of the appropriate size and a supply of clean rags/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 is better at washing out sludge and other deposits. After warming up the gearbox, 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. First unscrew the filler plug, then the drain plug and drain the oil into the prepared container.
4. After the oil stops leaking, wipe the drain plug, screw it back into place and tighten it to the required torque (30 Nm).
5. Pump the required amount of fresh transmission oil into the manual transmission housing through the filler/inspection hole - use a hand pump, syringe or funnel. The level can be considered normalized when the oil starts to flow out through the lower edge of the hole.
6. Screw the plug back into place and tighten it to the required torque (30 Nm). Lower the car to the ground.
7. Take the car for a short drive, after which check the drain and filler plugs of the manual transmission housing for signs of developing leaks.
