- The method for checking the gearbox oil level varies depending on your vehicle’s make and model. It can typically be done using either a dipstick or a filler plug.
- Ensure the area surrounding the dipstick or filler plug is clean prior to its removal. Clear any dust or particles to avoid polluting the transmission oil.
- Vehicles equipped with a dipstick should be pulled out and wiped clean with a rag. Then, reinsert the dipstick and pull it out to check the oil level. The dipstick will have markings indicating the correct oil level range.
- For vehicles equipped with a filler plug, remove it and use an appropriate tool or your finger to check the oil level. Guidance on checking transmission fluid without a dipstick is available.
- If the oil level is too low, you need to add more gearbox oil.
- After adding oil, check the level with the dipstick or through the filler hole to make sure it’s within the recommended range.
You typically require a dipstick to check the fluid level of a manual transmission. However, some manual cars do not have one, necessitating a separate purchase. To begin:
- Loosen the filler plug on the side or top of the transmission.
- Look for a hole where you can insert the dipstick or your finger (if the owner’s manual suggests) to check if the fluid level is correct.
- Take note of the colour and odour of the fuel.
Dark-coloured fuel or a burning smell is concerning. Additionally, there shouldn’t be any metal pieces or sludge present. If the fluid doesn’t appear normal, it may need to be replaced.
