My Chinese h330 has reached 4000 rpm, and the speed is still 40 yards.

Manual gear mainly checks whether the clutch mechanism and clutch plate are burned to cause slipping, which reduces the torque input of the engine. Check the direction of the automatic transmission-the coupling stalls, the valve body stalls, the automatic clutch plate of the gearbox is ablated, or the switch is damaged-the gearbox computer is forced not to upshift due to the heavy starting oil foot. The latter is a normal phenomenon. Ask the car master. 4S shop professional technician, 10 minutes to solve.
