NB: A deep sound between each gear and a gap , no smooth changes.
down shifts freeze for couple of seconds on a specific down shifting specially 4th and 3rd gears.
what should i do?
Get that code read, more than likely it will give you an idea of the faulty part. You can try the soft reset listed in the OP. My list of possibles on this would include the shift springs, gps, or even possible a wheel speed sensor (I know it sounds weird, but the wheel speed sensors do affect shifting)
