3 Key Steps to Master Sinotruk HOWO Gear Shifting and Boost Efficiency

  • In the world of heavy – duty trucks, Sinotruk HOWO has firmly established itself as a brand synonymous with reliability, power, and performance. Among the many crucial aspects of operating a Sinotruk HOWO truck, Sinotruk HOWO gear shifting stands out as a fundamental skill that can significantly impact the vehicle’s efficiency, lifespan, and overall driving experience.
  • Sinotruk HOWO trucks come equipped with a diverse range of gearbox options, each tailored to meet specific transportation needs. Let’s take a closer look at some of the most common gearbox types and their corresponding gear – shifting procedures.

Diverse Gearbox Options in Sinotruk HOWO​

Sinotruk HOWO offers a wide range of gearbox options to meet different transportation needs. The most common ones include 10 – speed, 12 – speed, 16 – speed manual transmissions, and Automated Manual Transmissions (AMT).

Manual Transmissions

10 - Speed Manual Transmission

  • Gearbox models such as HW10, HW19710, HW19710T, HW13710, HW15710, and HW18710 fall into the 10 – speed category. When shifting gears in these transmissions, a two – step clutch operation is typically required. For example, when moving from 1st gear to 2nd gear, first, depress the clutch pedal fully and shift the gear lever from 1st to neutral, then release the clutch. Next, depress the clutch again and move the gear lever from neutral to 2nd gear.​
  • When transitioning from the low – speed range (1 – 5 gears) to the high – speed range (6 – 10 gears), specifically when shifting from 5th to 6th gear, the process is a bit more involved. First, switch the valve on the gear lever from “L” (low) to “H” (high). Then, step on the clutch, move the gear to neutral, release the clutch, step on the clutch again, and finally, shift to 6th gear. It’s crucial to avoid skipping gears during the low – to – high – range shift. For instance, going from 4th to 6th gear directly can damage the deputy box synchronizer. The deputy box only switches to the selected range when the gear is in neutral. Also, when the vehicle speed exceeds 30 km/h, do not shift from a high – range gear to a low – range gear.
12 - Speed Manual Transmission
HW25712XSTL215037-1
  • Transmissions like HW19712, HW19712C, HW19712L, and HW19712CL are 12 – speed models. Similar to the 10 – speed, all gear shifts require the double – clutch method.
  • When moving from the low – speed range (1 – 6 gears) to the high – speed range (7 – 12 gears), for example, when shifting from 6th to 7th gear, first, switch the valve on the lever from “L” to “H”. Then, depress the clutch, move the gear to neutral, release the clutch, depress the clutch again, and shift to 7th gear.
  • Skipping gears during the low – to – high – range shift, such as going from 5th to 7th gear, can cause damage to the deputy box synchronizer. The deputy box operates as in the 10 – speed model, and the speed limit of 30 km/h for not shifting from high to low range also applies here.
16 - Speed Manual Transmission
16-Speed WY Transmission HW16WY21C005
  • Gearboxes including HW19716, HW20716, HW20716C are 16 – speed units. These transmissions feature a unique double – H mechanism. There are two neutral positions. Moving the lever left or right selects the range, with 1 – 4 gears and reverse in one range and 5 – 8 gears in the other.
  • Each gear has two conditions, low and high (e.g., 1H & 1L). When starting the vehicle, to get into 1L, place the lever at the left – hand neutral position with the air switch in the low position. Step on the clutch, move the lever to 1st gear, and release the clutch. When moving from 1L to 1H, move the air switch on the lever from “L” to “H”, step on the clutch, and then release it.
  • The process for other gear transitions is also carefully choreographed. For example, when moving from 4H to 5L, first move the air switch from “H” to “L”, step on the clutch, move the lever from 4th to the left – hand neutral, slide it to the right – hand neutral, release the clutch, step on the clutch again, and move the lever to 5th gear. As with the previous models, do not shift from high to low range when the vehicle speed is above 30 km/h.
Automated Manual Transmission (AMT)​

  • The HW20716A is an example of an AMT in Sinotruk HOWO trucks. The shifting process in AMT is controlled by the Transmission Control Unit (TCU) automatically, although the driver can also send out Sinotruk HOWO Gear Shifting requests. This significantly reduces the driver’s fatigue and enhances driving comfort. During any shifting process, the gear position indication sign on the instrument panel will flash. The instrument also displays information such as the current operating position of the gearbox, with an upward – pointing triangle (▲) flashing to indicate gear – up and a downward – pointing triangle (▼) flashing to indicate gear – down. The AMT offers two operation modes: auto – mode and manual – mode.​
  • Auto – mode: This is the default operation mode of the control system. In auto – mode, the driver only selects the startup gear (forward, reverse, or neutral) using the shift lever. During driving, the gearbox control system automatically selects the most suitable gear based on the vehicle’s speed, load, and driving conditions. However, the driver can still interfere with the Sinotruk HOWO Gear Shifting operation using the handle.​
  • Manual – mode: In manual – mode, the driver decides when to shift and which gear to select. The clutch operation is automated under the system’s control, meaning that during startup, Sinotruk HOWO Gear Shifting, and stopping, the clutch engages and disengages automatically. The driver can switch between auto – mode and manual – mode using the handle button, and the instrument panel screen will display the current operation mode in real – time.

Benefits of Proper Sinotruk HOWO Gear Shifting Technique

  • Proper gear shifting in Sinotruk HOWO trucks brings several benefits. Firstly, it optimizes fuel efficiency. By shifting gears at the right engine speeds, the engine can operate within its most fuel – efficient range. For example, in a long – haul transportation scenario, a driver who shifts gears correctly can save a significant amount of fuel over the course of a year, reducing operating costs.
  • Secondly, correct Sinotruk HOWO gear shifting enhances the lifespan of the transmission. Skipping gears or shifting at inappropriate speeds can cause excessive wear and tear on the gears, synchronizers, and other transmission components. In a Sinotruk HOWO truck used for heavy – duty construction or mining operations, where the vehicle is constantly under load, proper Sinotruk HOWO gear shifting becomes even more crucial to ensure the transmission can withstand the harsh working conditions.
  • Finally, smooth Sinotruk HOWO gear shifting improves the overall driving experience. A driver who can shift gears seamlessly can maintain a more consistent speed, reducing jerking and vibrations in the vehicle. This is not only more comfortable for the driver but also for any passengers or cargo being transported. In urban delivery scenarios, where frequent stops and starts are common, smooth Sinotruk HOWO gear shifting can also help in reducing the stress associated with driving in traffic.
