Do Automatic Transmission New Cars Have a Break-in Period?

[DeJosie]

Automatic transmission new cars do have a break-in period. Below are the precautions for the car break-in period: Avoid high-speed driving: New cars have speed limits during the initial driving phase, generally set between 50 to 100 km/h. Additionally, it is typically required that within the first 1,000 kilometers, when the throttle is fully open, the speed should not exceed 80% of the maximum speed. It is also advised to monitor the engine tachometer and speedometer to ensure both engine speed and vehicle speed operate at moderate levels. Avoid full-load operation: Operating a new car at full load can cause damage to the mechanical components. Avoid long-distance trips: Taking a new car on long-distance trips will prolong the continuous operation time of the engine, leading to increased wear on the mechanical components.
