How to Operate the Gear Shift in Large Vehicles?

Large trucks change gears through the fast-slow bridge shift lever. Introduction to the Fast-Slow Bridge Shift Lever: Large trucks use a fast-slow bridge system with a shift lever that allows switching between gear modes. The shift lever is then used to change gears within each mode. Specific Methods: Depress the clutch fully, apply appropriate and steady force when shifting gears, avoiding excessive force. When upshifting, quickly press the accelerator pedal. You can lightly tap the accelerator in neutral to match the engine speed with the transmission speed before engaging the desired gear. Do not rush to press the clutch first; apply the brakes first.
When operating the gears in a large vehicle, the key is to press the clutch all the way down, gently step on the accelerator, and wait until the vehicle is stable before shifting gears. I've been in this line of work for decades, and I always start in first gear, feeling the car move before adding a bit of throttle to shift to second. The timing for shifting gears depends on the tachometer, usually around 2000 RPM; otherwise, the engine will roar. When going uphill, it's essential to shift to a lower gear in advance, or the vehicle might roll backward, which is quite dangerous. When parking, don't just shift to neutral; remember to engage the handbrake, especially on slopes. Be extra careful when driving in the rain—the roads are slippery, and it's easy to lose control. Practice starting, stopping, and shifting gears in an open area regularly to get a good feel for it. On long drives, make sure to rest well; fatigue can slow down your shifting and lead to mistakes.
When I first learned to drive a large vehicle, the gear operation was a complete mess. I would shift gears without fully depressing the clutch, causing the vehicle to suddenly stall, which really startled me. Later, my instructor told me to take it slow: start moving in first gear, add a bit of throttle before releasing the clutch, and the vehicle wouldn’t jerk. When shifting gears, you need to pay attention to the speed and engine sound—shifting too fast can cause it to grind, while shifting too slow makes the vehicle sluggish. I made plenty of mistakes, like failing to start on a slope several times before learning to shift into a lower gear in advance. Looking back now, it’s best for beginners to practice starting, stopping, and shifting repeatedly in an open area to avoid messing up at traffic lights. Proper operation protects the transmission and extends the vehicle’s lifespan.
