How do you top up Renault traffic gearbox manual?

To top up the manual gearbox oil in a Renault Trafic, first ensure the vehicle is on a level surface and the engine is off. Locate the gearbox fill plug, usually found on the side of the gearbox, and remove it using the appropriate tool. Using a pump or a funnel, add the recommended gearbox oil until it reaches the fill level, which is typically just below the fill hole. Finally, replace and secure the fill plug to complete the process.
