> Check Gear Transmission Oil
> Also possibly could be an issue with Clutch Assembly
Suggest to test drive at slight higher speed tomorrow morning, and check
> Are you able to change Gear on Higher Speed or Stiffness on it
> Any Vibration on Gear Lever
> Is there a Play in Clutch - means Clutch pedal depressing just more than regular level
Then, basis outcome report at nearest Service center to get car inspected
Hope should help !!
