Shot peening is applied to the first, second, third and fifth gears of the manual transmission for improved strength and durability to accommodate the higher engine torque. A double cone synchronizer is also provided in the first gear position, in addition to those previously used in the second and third gear positions, for smoother, easier shifting. Moreover, a pull-type clutch for easier operation has been adopted in the manual transmission on turbocharged models.
