Should the RPM Be Raised to 2000 When Shifting from First to Second Gear?

When shifting from first to second gear, the RPM should be raised to 2000. The reasons for high RPM are: 1. Sudden increase in throttle opening; 2. Fuel injector leakage or blockage; 3. Slippage or damage to the air conditioning clutch; 4. Air intake system leakage; 5. Insufficient engine power output. Solutions for high RPM include: 1. Adjusting the throttle opening; 2. Replacing the fuel injector, air conditioning clutch, air intake system, or engine. The causes of unstable engine RPM are: 1. Oil residue or carbon buildup in the throttle; 2. Dirty intake tract; 3. Blockage in the fuel system, particularly the fuel injector; 4. Faulty intake manifold.
Shifting RPM is actually quite flexible. Having driven manual transmissions for over a decade, I've found 2000 RPM to be a reference point rather than a hard rule. When driving in fuel-saving mode, shifting from first to second gear at 2000 RPM does feel smooth, especially sufficient for starting at traffic lights. However, when climbing hills or wanting to accelerate for overtaking, I'll push to 2500 or even 3000 RPM before shifting – that's when torque is more abundant and the engine doesn't feel strained. Each car has its own character; my old Jetta shifts smoothly at 2000 RPM, but my friend's turbocharged car needs to be revved to 2300 RPM to avoid jerking. The key is to pay more attention to the body vibration and engine sound – that's far more reliable than rigidly watching the tachometer.
