Clutch and steering are the two mechanical systems that the driver controls. One said that it wears out faster than the other: it's the clutch system of course. In particular with the gearbox, in close connection. It happens rather regularly that gearshift problems occur on this + str (XXX) +. And even if the clutch is often the cause, sometimes we are surprised at the reason for the problems. In addition, it avoids from time to time to change the whole kit. Here are the gear change issues the most regular.
+ str (XXX) +: Impossible to pass one of the speeds
It often happens that one of the gears no longer shifts. Or just even or odd speeds. As a result, the clutch is damaged. But that is not inevitably linked to the entire clutch kit or gearbox of your + str (XXX) +. It is possible that the problem comes from a link or a rubber which holds it. The problem can still come from the gearbox. You can remove it to check that no external component is blocking it. If it is defective, it will have to be changed.
Unable to change gear once the + str (XXX) + engine is started
Unfortunately, this is a fairly recurring problem. Since the engine block is off, it is still possible to shift your gears, this implies that the + str (XXX) + gearbox is operational. Once the engine block is on, it is impossible. The problem comes from the clutch. Often it will be necessary to replace the entire clutch kit. You can always dismantle it and check the condition of all the components. For your information, it is advisable to replace the clutch every 150 km.
+ str (XXX) +: no speed passes
If none of the gears work, the engine stopped as lit, it's really annoying. One thing to check is the condition of the gearbox of your + str (XXX) +. There is a good chance that the latter is HS. In order to understand where the problem comes from it's relatively easy. If you can push the lever into the guide of one of the gears, but the gear does not take, the clutch is probably the problem. If the lever seems to be blocked and you cannot push it, the problem probably comes from the gearbox. In both cases, you will most likely have to replace one or more parts.
