Thank You mstern001 for your reply, but actually the problem was never of the gearbox…today i got my car to a service center and they found the problem. It was not in the transmission..but in the exhaust. The filter of the exhaust (which is inside the exhaust pipe) was blocked from one side and the car could not throw out the power from the engine out. It had happened because one of the quality of fuel was bad, and it made the exhaust filter get blocked. So the point is, the car is like new, the acceleration is unbelievable. I cannot actually believe my eyes seeing what a 84hp 1.2 liter 4 cylinder engine can do. However, most of the times, one needs to replace the exhaust altogether, but in my scenario, i just got the exhaust filter removed with all the dust and dirt inside it. Still on the old exhaust.

Thank you so much for the support.
