heavy Punto SCHALTPROBLEM: Aisles often don’t go in… ASSISTANCE

Hello, I have problems with my Punto S, 1.1 55 HP, BJ 1996, KM 161000 Sometimes the first and third gears are only very difficult or not at all anymore and the reverse gear only crashes with force. 2. 4th and 5th gears are never a problem. Sometimes everything is OK too and everything runs like with a new car. But before that something strikingly occurred to me: Sometimes the shift lever from the idle to the first and third gears (so forward) has only a totally short You don’t think the gear is in it yet, but it is and back into the 2nd and 4th gears it has a much longer (normal) way. If this Situartion occurs I often have problems in idle, then the idle area is so small, as if a gear is in it and then the switch knob vibrates. Then it goes again a few meters good, 1st and 3rd gears have a normal switching path again. Before that I just made it to the garage, since I have first It seems to me that something is moving. Is everything totally strange. Sometimes it doesn’t work. Last week the clutch rope was renewed, so it went well for many days. Now the problem is just as described again. Clutch was renewed something over a year ago. What could that be? A friend said it could be the shift, too little gear oil could be I urgently need your help, I have to go to the TÜV in August. Who has experience or idea what this could be?
