Do Automatic Transmission Cars Need a Break-in Period?

[StIsabel]

Automatic transmission cars do require a break-in period. Proper break-in can reduce fuel consumption, extend the vehicle's service life, decrease the probability of malfunctions during daily use, and lower maintenance costs. The break-in period typically covers the first 1,000 to 3,000 kilometers. During the initial 0-500 kilometers, avoid sudden acceleration and hard braking, and keep driving speed and engine RPM at moderate levels. Key precautions for breaking in an automatic transmission car include: 1. Maintain speeds below 70 km/h during the first 500 km; between 500-1,000 km, you may gradually increase speed and engine RPM, keeping engine speed around 2,500 RPM; 2. Vary your speed frequently - unlike manual transmissions, automatic transmissions require speed variation for proper break-in; 3. Avoid heavy loads - drive with minimal cargo or light loads during break-in, as overloading may damage mechanical components.
