When you\u2019re spec\u2019ing out a heavy-duty truck for long-haul or regional haul work, the transmission choice often gets less attention than the engine or the rear axle ratio. But in my years running fleet maintenance and evaluating trucks across the U.S. and international markets, the gearbox is usually where the operational cost is won or lost. The HOWO Truck gearbox guide comparison between the HW19710 and HW19712 isn\u2019t just about gear counts\u2014it\u2019s about matching the box to the route, the cargo, and the driver. Both are Sinotruk units, but they behave differently under load, and picking the wrong one can cost you thousands in fuel and downtime.<\/p>\n
These two transmissions are commonly found in HOWO 6×4 and 8×4 tractors, especially in markets like Australia, Russia, the Middle East, and increasingly in North American fleets looking for value-oriented Chinese trucks. The HW19710 is a 10-speed unit, while the HW19712 is a 12-speed. That might sound like a simple difference, but the internal gearing, the weight, and the shift logic create distinct driving experiences. From my time in the field, the 12-speed is not automatically the better option\u2014it depends heavily on whether you\u2019re hauling 40 tons of coal on a grade or running 25 tons of general freight on flat interstate.<\/p>\n
