The clutch and the steering are two mechanical devices that the motorist controls. One has that said the habit of deteriorating more quickly than the other: it is the clutch system of course. With obviously the gearbox, which is closely related. It happens relatively frequently that gearshift problems occur on the + str (XXX) +. And even if the clutch is regularly involved, it happens that we have surprises about the reason for the problems. Also, it avoids at times having to change the complete kit. Here are therefore the gear change issues the most regular.
+ str (XXX) +: Impossible to pass one of the speeds
It happens from time to time that one of the gears does not pass any more. Or only even or odd speeds. In this situation, the clutch is damaged. However, this is not necessarily related to the entire clutch kit or gearbox of your + str (XXX) +. The problem may be with a connecting rod or rubber that holds it. The malfunction can still come from the gearbox. It can be removed to check that no foreign element is blocking it. If it is damaged, it will have to be replaced.
Unable to shift gear once the + str (XXX) + engine is running
Unfortunately, this is a fairly common malfunction. Since the engine is off, it is still possible to shift gears, which means that the + str (XXX) + gearbox is in good condition. Once the engine is running, it is impossible. The fault is with the clutch. In general, it will be essential to change the complete clutch kit. You can still remove it and see the condition of all the parts. For information, it is still recommended to change the clutch every 150 km.
+ str (XXX) +: no speed passes
If none of the gears are working, with the engine off or running, it's really annoying. One thing to watch is the wear and tear on your str (XXX) + gearbox. There is a good chance that this one is HS. To understand where the dysfunction comes from is rather easy. If you can push the lever into a gear guide, but the gear won't pick up, the clutch is probably malfunctioning. If the lever seems stuck and you cannot push it, the problem is probably with the gearbox. In both cases, it will certainly be necessary to change one or more parts.
