Which gear should be used when pushing an automatic transmission car?

[StAlexa]

Automatic transmission cars should be pushed in the N (Neutral) gear. Below is an introduction to automatic transmissions: Operating principle: The engine's power is transmitted through the gearbox, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume 10% more fuel than manual transmissions. Whether manual or automatic, more gears mean better fuel efficiency. Driving technique: For manual transmission cars, upshifting should be done at higher RPMs. Engines are designed to operate at higher RPMs, with parameters like dynamic balance and rotational inertia optimized for high-speed operation. Prolonged operation at abnormal RPMs increases internal component stress and wear, often leading to vibration and knocking, which affects engine lifespan. Using 3000 RPM as the upshift point ensures post-shift operation at around 2300 RPM, keeping the engine within its healthy operating range.
