The clutch and the steering are the two mechanical devices that the motorist steers. One said that it wears out faster than the other: it's the clutch naturally. With of course the gearbox, which goes with it. It happens rather regularly that gearshift problems occur on the + str (XXX) +. And even if the clutch is frequently involved, it sometimes happens that we are surprised at the source of the problems. Also, it avoids from time to time to change the whole kit. So these are the gear change issues the most regular.
+ str (XXX) +: Impossible to pass one of the speeds
It sometimes happens that one of the gears no longer shifts. Or only even or odd speeds. In this case, the clutch is in poor condition. However, this is not necessarily linked to the whole clutch kit or gearbox of your + str (XXX) +. It happens that the dysfunction comes from a link or a rubber which holds it. The malfunction can also happen from the gearbox. It is possible to disassemble it to check that no external element is blocking it. If it is defective, it must be replaced.
Unable to shift gear once the + str (XXX) + engine is running
It is unfortunately a rather frequent dysfunction. Since the engine is off, it is still possible to shift your gears, this implies that the gearbox of your + str (XXX) + is operational. Once the engine is started, it is impossible. The malfunction comes from the clutch. Usually it will be necessary to change the entire clutch kit. You can try to disassemble it and check the condition of each of the parts. For your information, it is still recommended to change the clutch every 150 km.
+ str (XXX) +: no speed passes
If none of the gears work, the engine stopped or in working order, it's really annoying. The first thing to check is the wear and tear on the gearbox of your + str (XXX) +. There may be a high probability that the latter will be out of service. In order to discern where the malfunction comes from it's quite easy. If you can put the lever in the guide of one of the speeds, but it does not take, it is the clutch which probably presents a malfunction. If the lever seems to be blocked and you cannot push it, the malfunction certainly comes from the gearbox. For both, it is very likely to change one or more parts.
