I have ford fiesta. Car was in good condition. All of a sudden, I started facing a weird issue which my mechanic also facing tough time identifying the real problem. My car is running fine from the first start in the morning. I am able to change the gears smoothly. After 15mins of driving gear shifting slowly gets tight and after half an hour, I have to put more pressure to change the gears. After I stop the car and let the car cool down, the gear shifting getting back to normal and this cycle repeats. I don't see any problems with the clutch as it is recently changed.

Gear oil is good. Clutch is engaging and disengaging fine. No grinding noise observed while disengaging clutch and while shifting gears.

This is happening with all the gears. Did anyone face this kind of issue or anyone knows the fix?

    Well, that's exactly a situation which can be caused by the clutch not fully disengaging, so don't rule it out. The clutch can be free enough as to not transfer any torque from the engine to the wheels (a lot is needed to move the car) when in gear and stationary, but not free enough to allow the idling gears to move slightly so they can mesh from neutral (which doesn't take much force).

    The reason I asked about the age of the clutch is if the clutch is tight and not broken in completely, it will swell some during operation (ie: engage/disengage cycle) due to heat. This can cause a little bit of drag on the clutch, which means it isn't fully disengaging. As soon as it cools down, no problem. This can be very typical of a new clutch, so would not discount it.

    In addition to the issue with the clutch being mis- adjusted (which I agree should be your #1 suspect since you recently had it serviced!) you may have a bent or improperly installed shift linkage, bent shift forks in the transmission, improperly filled transmission (i.e. wrong fluid), or another problem related to removal and re-installation of the transmission.
