What is the reason why the truck does not move after engaging the gear and releasing the clutch?

Truck not moving after engaging the gear and releasing the clutch generally has two main reasons: one is clutch plate damage, and the other is gear shift component damage (such as shift lever or gear shift mechanism). If the clutch plate is damaged, replace the clutch plate. If the gear shift components are damaged, replace the corresponding parts. Below is some relevant information about trucks: 1. Trucks usually have 8 gears, with gears 1~4 being low-speed gears and gears 5~8 being high-speed gears. 2. Trucks generally start in 2nd gear and then gradually shift up. Starting in a high gear will increase wear on the vehicle. Unless under special circumstances, do not skip gears when shifting. Generally, high-speed gears are more fuel-efficient than low-speed gears, so after starting, shift up gradually and avoid driving in a gear that is too low.
I deal with trucks quite often, and this situation is usually related to the clutch. If the clutch disc is severely worn or the pressure plate is damaged, power cannot be transmitted to the transmission when the clutch is released. Transmission issues could also be the cause, such as the gear synchronizer not locking properly—the gear may appear engaged but isn’t fully in place, preventing the vehicle from moving. Additionally, don’t forget to check if the drive shaft or axle is stuck, especially in older vehicles prone to rust or damage. A handbrake not fully released can also cause this, something many drivers overlook. If the truck doesn’t move, avoid flooring the accelerator; instead, try shifting gears back and forth to feel for issues. For a proper fix, contact a professional mechanic immediately, especially since trucks carry heavy loads and safety can’t be ignored. Regular maintenance checks on the clutch system and transmission fluid can help prevent such problems.
I've been driving trucks for over a decade and encountered this issue several times. The most likely cause is the clutch problem - when the pressure plate wears out, releasing the clutch doesn't fully engage and power can't be transmitted. Transmission gears not being properly engaged or insufficient fluid can also cause power loss. In winter, thick oil makes gear shifting even harder. Also check if the handbrake is fully released - sometimes slight sticking can prevent movement. My routine is to gently press the accelerator before releasing the clutch to check for response. If that doesn't work, I'll get out and check if the driveshaft is rotating. Minor issues like refilling transmission fluid I can handle myself, but for complex problems I'll drive straight to the repair shop. Never delay repairs - early intervention saves both money and trouble.
