The effects of suddenly shifting to R while driving an automatic transmission car include engine stalling and reduced braking force. There are three key driving techniques for automatic transmission cars: When waiting at a red light, depending on driving habits, temporarily stop by pressing the brake and keep the gear in D, because the torque converter inside the transmission is equipped with a reaction wheel with a one-way clutch, which amplifies the torque from the engine crankshaft and does not rotate at engine idle speed, only engaging when the engine speed increases; When starting, the gear lever can only be moved out of P or N and into a driving gear after pressing the brake pedal. Releasing the brake pedal allows the vehicle to move slowly. The purpose of pressing the brake in advance is to ensure the safety of the driver and the vehicle; The engine can only be started when the gear lever is in the P or N position. If the gear lever is in a driving gear such as D or R, the engine cannot be started.
