After driving my car for about 40mins, when I changed the gear from 2 to 3, the car will start to drag regardless of acceleration. I will have to bring the gear back to 2. Even on gear 2, it will still drag and becomes difficult to move. At this stage, I have to turn the ignition off and wait a while before I start driving again .
This problem always surfaces when I've driven for long period of time.
I recently changed the clutch, it doesn't help.
Somebody please help!
