Should an automatic transmission car shift gears first or release the handbrake first?
1 Answers
An automatic transmission car should shift gears first and then release the handbrake. Below is an introduction to driving an automatic transmission car: 1. After shifting gears, the handbrake should be released as soon as possible: If the gear is engaged but the handbrake is not released, all the power output by the engine will be absorbed by the torque converter, causing the torque converter's temperature to rise sharply. Prolonged operation in this state can burn out the torque converter. For dual-clutch transmissions, after engaging the gear, the clutch friction plates will be in a semi-engaged state. Prolonged semi-engagement can cause the friction plates to burn out, so it is necessary to start moving as soon as possible. 2. When parking, the handbrake should be engaged first and then the gear should be shifted: In the car's transmission, the P (Park) gear has a set of pawl and gear mechanism at the end of the output shaft. When the transmission is shifted into P gear, the pawl is pressed down to engage with the gear, thereby achieving a locking effect. If the car is pushed while only in P gear, the vehicle can be moved because the pawl and gear have a relatively large engagement gap. Additionally, the P gear pawl and gear mechanism also have a self-protection mechanism. If the pushing force reaches a certain level, the pawl will spring open to avoid damaging the transmission.
