The differences between automatic transmission and manual transmission: Different principles: Manual transmission requires the driver to manually shift gears by moving the gear lever to change the gear engagement positions inside the transmission, thereby altering the gear ratio to achieve speed changes. Automatic transmission, on the other hand, allows the driver to control the accelerator pedal as needed during driving. The automatic transmission can automatically shift into different gears based on engine load and the vehicle's operating conditions, adjusting gear shifts according to vehicle speed and engine RPM. Different characteristics: Manual transmission offers stable performance, high transmission efficiency, and better fuel utilization. Automatic transmission provides convenient operation, flexible gear ratios, and comes in various types. Different transmission efficiency: Unlike manual transmission, which relies entirely on mechanical transmission, automatic transmission uses hydraulic transmission via a torque converter, leading to differences in working efficiency and directly resulting in variations in fuel consumption.

What are the solutions when a car won't start due to a dead battery?

Push the car manually to assist the combustion of the air-fuel mixture in the engine cylinders. Use cables to connect the battery terminals, paying special attention to connect the positive terminal to the positive terminal and the negative terminal to the negative terminal. Drive the car near a charging device and connect it with charging cables to replenish the battery power in time. Cars should be driven regularly. Prolonged inactivity can lead to battery discharge, brake disc rust, and reduced tire lifespan.

What is the tutorial for removing the ball from the car's interior rearview mirror?

The car's rearview mirrors are located on both sides of the front of the car and inside the front of the car. The car's rearview mirrors reflect the situation behind, beside, and below the car. Pinch the cylindrical part at the back of the rearview mirror, then rotate it counterclockwise by 45 degrees to remove it. After removal, the base of the interior rearview mirror will still adhere to the front windshield. When removing, be careful to apply appropriate force to avoid damaging the front windshield. Note that removing the interior rearview mirror can easily damage the base, leading to looseness after reinstallation.
