The clutch and the steering are the two mechanical systems that the driver controls. One, however, tends to wear out faster than the other: this is of course the clutch mechanism. With obviously the gearbox, which goes with it. It happens relatively regularly that gearshift malfunctions occur on this + str (XXX) +. And even if the clutch is often involved, it happens that we have surprises about the source of the malfunctions. In addition, it sometimes avoids replacing the entire kit. Here are the gearshift malfunctions the most usual.
+ str (XXX) +: Impossible to pass one of the speeds
It happens from time to time that one of the speeds does not pass any more. Or only even or odd speeds. The clutch is therefore in poor condition. But that is not necessarily due to the whole clutch kit or gearbox of your + str (XXX) +. It is possible that the concern comes from a link or a rubber that holds it. The problem can also come from the gearbox. It can be removed to check that no foreign element is blocking it. If it is damaged, you must replace it.
Unable to change gear once the + str (XXX) + engine is started
Unfortunately, this is a fairly common concern. Since the engine block is off, it is still possible to shift gears, which means that the + str (XXX) + gearbox is in good condition. Once the engine block is on, it is impossible. The concern must come from the clutch. Usually it will be necessary to change the entire clutch kit. You can always put it down and check the condition of each part. As a reminder, it is still recommended to change the clutch every 150 km.
+ str (XXX) +: no speed passes
If none of the gears work, with the engine off as on, it's really annoying. The first thing to check is the wear of the gearbox of your + str (XXX) +. There is a high probability that the latter is HS. In order to understand where the problem comes from, it is quite easy. If you can put the lever in the guide of one of the speeds, but the speed does not pick up, the clutch is certainly the problem. If the lever seems stuck and you can't push it, the problem is probably with the gearbox. In both cases, you most likely need to change one or more parts.
