My car automatically shifts to 1, 2, 3, 4, and 5 gears without any problems. However, when it shifts to 6th gear, it suddenly goes from 2000 rpm to 5000 rpm and becomes unstable, as if it's out of gear. The same problem occurs with the manual 6th gear. We are investigating the cause in Mersin... I wonder if anyone has experienced this issue with their car...
