What does 'band' mean in a car?
2 Answers
In a car, 'band' refers to the button that switches the radio between different frequency bands, allowing you to toggle between FM1, FM2, FM3, and AM. Other common buttons on a car radio include: 1. 'Mode' for selecting modes; 2. 'Vol' for volume control; 3. 'Scan' for searching radio stations; 4. 'Sel' for selection; 5. 'Tune' for sound effects; 6. 'Int' for preview; 7. 'Rpt' for repeat playback; 8. 'Rdm' for random playback. Frequently used buttons in a car include: 1. Fuel tank cover; 2. Trunk lid; 3. Window switches; 4. Air recirculation; 5. Rear window defogger; 6. Rearview mirror adjustment.
In an automatic transmission, the band refers to the brake band, which is somewhat like a thick rope wrapped around the drum. It helps lock specific gear combinations during gear shifts, making the shifting process smoother. I often study car repairs and encounter many car owners complaining about jerky shifts or loud noises, only to find out it's due to worn or burnt bands. Automatic transmissions rely on hydraulic pressure to operate the bands, which can easily overheat and fail in older models, especially in frequent stop-and-go traffic. When changing transmission fluid, make sure to use the correct type, and replacing it every 40,000-50,000 kilometers can extend its lifespan. Don’t underestimate the issue—band failure can cause slipping, loss of gears, or even engine stalling. If symptoms appear, it’s best to visit a professional shop for a diagnostic scan rather than attempting DIY fixes.
