Is It Harmful for an Automatic Transmission Car to Roll Forward in Reverse (R) Gear?

[ValeriaLynn]

Rolling forward in reverse (R) gear in an automatic transmission car does pose some harm, though the harm is not significant. It can accelerate clutch slippage and cause the clutch to heat up quickly. Below is an introduction to automatic transmission cars: 1. Overview: Generally, cars equipped with automatic transmissions (AT) adjust speed automatically. While driving, the control system of the automatic transmission selects the appropriate gear based on engine speed and load, replacing the driver's subjective judgment of timing and gear shifting. In simple terms, an automatic transmission car is a "foolproof car." 2. Principle: Automatic transmission cars typically use hydraulic transmission devices to replace the mechanical clutch in manual transmission cars, hence there is no clutch pedal. When the engine speed is low, the torque transmitted by the fluid is limited and insufficient to propel the car forward. When the gear lever is placed in the drive position and the brake pedal is released, as the throttle is applied and the engine speed increases, the transmitted torque grows, pushing the car forward.
