The clutch and steering are the two mechanical devices that the driver steers. One is nevertheless used to wear out faster than the other: it is the clutch device of course. Obviously with the gearbox, in close connection. Rather regularly, gearshift malfunctions occur on the + str (XXX) +. And even if the clutch is regularly involved, it sometimes happens that we are surprised at the reason for the malfunctions. In addition, it sometimes avoids replacing the complete kit. So these 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 gears does not pass any more. Or just even or odd speeds. In this case, the clutch is in poor condition. However, this is not necessarily related 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 also come from the gearbox. It is possible to remove it in order to check that no foreign component is blocking it. If the latter is damaged, it will have to be changed.
Unable to shift gear once the + str (XXX) + engine is running
Unfortunately, this is a fairly common problem. Since the engine is off it is possible to shift your gears, this implies that the gearbox of the + str (XXX) + is in good condition. Once the engine is started, it is impossible. The problem must come from the clutch. Usually it will be essential to change the complete clutch kit. You can always disassemble it and look at the condition of each of the parts. For information, it is advisable to change the clutch every 150 km.
+ str (XXX) +: no speed passes
If none of the gears pass, the engine off or in working order, it's really annoying. One thing to watch is the wear and tear on the gearbox of your + str (XXX) +. There is a high probability that the latter will be HS. To discern where the problem comes from, it's pretty easy. If you can push the lever into the guide of a speed, but the speed does not engage, the clutch is probably the problem. If the lever seems to be blocked and you cannot push it, the problem is certainly the gearbox. In both cases, it will most certainly be necessary to change one or more parts.
