Why does an automatic transmission maintain high RPM without shifting up?

[VonKathryn]

This is a computer-programmed feature (overtaking mode). When the driver accelerates aggressively, the computer interprets it as the vehicle needing to overtake or requiring more power. Since higher gears provide less torque, the computer maintains the current gear or downshifts to enhance performance. Here's an introduction to automatic transmissions: 1. Classification: As the name suggests, an automatic transmission doesn't require manual gear shifting by the driver. The vehicle automatically selects the appropriate gear based on speed and driving conditions. 2. Operation: Driving an automatic transmission vehicle primarily involves using Park (P), Reverse (R), Neutral (N), and Drive (D) gears to meet general driving needs. For specific driving conditions, other functional gears may be required.
