What Causes Mismatch Between Speed and Gear in Automatic Transmission?

[MaciAnn]

Transmission malfunction requires professional repair. Below are key points about automatic transmissions: 1. Operating Principle: Engine power is transmitted through the gearbox, a critical factor affecting fuel consumption. Generally, automatic transmissions consume 10%+ more fuel than manual ones. More gears mean better fuel efficiency for both types. 2. Driving Tips: For manual transmissions, upshift at higher RPMs. Engines are designed to operate optimally at higher revolutions - components' dynamic balance and rotational inertia parameters are calibrated accordingly. Prolonged low-RPM operation increases internal wear, causing vibration/detonation and reducing lifespan. Shifting at 3000RPM maintains post-shift RPM around 2300, keeping the engine within its healthy operating range.
