This symptom can occur with both manual and automatic gearboxes.
Clutch system malfunctions manifest themselves differently depending on types of gearbox. Most often, the clutch pedal becomes soft or, conversely, extremely hard. In both cases, it is difficult, if not impossible, to operate, which complicates gear changes. It may also be that the clutch slips and the symptom becomes more pronounced over time, or that you feel vibrations in the pedal. The clutch may also overheat, squeak or jerk...

The oil change of the gearbox is part of routine maintenance. In the case of a manual gearbox, it's a good idea to schedule the first oil change as soon as you've passed the 100,000 km.

Always respect the recommended intervals, as your gearbox needs clean oil in sufficient quantity. Although considered as a whole, the gearbox is in fact a collection of several gears and parts that operate permanently until the car stops. Continuous friction can cause the numerous gears to heat up and wear out. Gearbox oil not only cools them, but also lubricates them. As it is used continuously, transmission oil diminishes and the lubrication becomes more difficult. Checking the oil level at regular intervals is therefore essential.
Please note: gearbox oil changes are independent of engine oil changes. Not only are the recommended frequencies different, but the type of oil used is also different.
Here are a few warning signs that may tell you it's time to change your gearbox oil:

  • From cracking noises when changing gear;
  • The gears jump even though you don't interfere with the transmission mechanism;
  • You notice traces of oil transmission oil on your parking space or on the roads you've travelled;
  • From jerks at start-up or jerking during acceleration.
