Mercedes stops when the gear is engaged

Manual gearbox: In no case do no-go's with manual gearboxes

coupling and Manual transmission are that what bothers you when starting up? The top 5 things to avoid when using manual gearshifts. Otherwise there is a risk of gear failure!

In times in which automatic and direct shift transmissions are increasingly taking over the field, the manual transmission in particular represents direct communication between humans and mechanics. While the automatic makes it possible to glide around carefree, the gear shift is for driving in its purest and coolest form. But be careful, too much of the casualness and the clutch makes the exit. Despite all the looseness, certain basic rules must be observed with the hand switch: Five things that must not be done with a manual switch under any circumstances. >> Calculate a clutch change here at Vergölst

So don't put your hand on the gear knob (video):


Under no circumstances do this with manual transmission

1. Never leave your foot on the clutch!
If you keep your foot on the clutch pedal, slip is the order of the day. The frictional connection between the flywheel (engine) and clutch disc (gearbox) has not yet taken place. The consequence is on the one hand material abrasion on the clutch disks, on the other hand the release bearing is damaged. Since it does not come into the rest position, the coupling forces act on the bearing. To explain what the release bearing does: Put simply, it is responsible for separating the flywheel and clutch disc.

2. Never accelerate in high gear at low speed!
Accelerating at low speeds - for example at 50 km / h and in fifth gear - does not damage the clutch, but it does damage the engine all the more. Anyone who slips on the gas in high gear but at a low speed suddenly increases the pressure on the entire drive train. The bicycle is a good comparison: Anyone who has ever wanted to start off in high gear has noticed the forces against which they have to work. It is similar with the car.

3. Never let the clutch slip in order to stop on a slope!
From a mechanical point of view, "letting it slip" means that the two disks of the clutch rub against one another with insufficient adhesion. Finally, the release bearing also ensures that the discs do not touch down completely. That is why "letting it slip" is much more likely to wear the clutch linings. After all, they are only designed for fast, not artificially drawn out gear changes and high static friction. So use the brake or handbrake, because that's what they are made for!

4. Never leave the gear engaged at the traffic lights!
When you stop at the red light, always take out gear, shift into neutral and disengage the clutch. It is less about the clutch linings than about the release bearing. That is because this is permanently stressed if the driver remains on the clutch. In this case, the force of the clutch spring continues to bear on the release bearing, but it is not designed for this. By the way: The argument that the traffic light can be started faster with a gear engaged is likely to have become obsolete in view of the crowded city centers, right?

5. Never leave your hand on the gear shift!
In the case of classic shift linkages, the pressure of the hand can lead to earlier wear of the transmission, as the shift linkage can no longer work freely. The forces working under the gear lever can be read from the movement of the gear lever when accelerating or releasing the gas. Apart from that, both hands belong on the steering wheel anyway! The workshop we are friends with knows whether your own car has a classic gearshift linkage or a cable.
