Hi,

I prefer using my car at Manual mode to Automatic mode. Because at automatic mod not comfortable for me.
But I have problem at Manual mode. Sometimes ,after first start while I want gear up, it goes down suddenly. Exmpl ;At 2.gear after some seconds it goes down to 1. gear. No any reason and any faulty at screen.
If I stop the car and restart again, it solves and i can use at manual mode normally.
But somethimes it happen at 4. or 5. gear, suddenly gear goes down with high rpm. This situation becomes dangerous.
I want solve this problem. Can you help please ? ?

These are complex systems and can be difficult to troubleshoot, so you need to get Diagbox on it and see if you are getting any specific fault codes back. It may be that the gear selection system needs recalibrating or the clutch bite point needs programming again, but I wouldn't do anything until you have a proper diagnostic done.
