Is It Illegal to Replace a Car Transmission?
1 Answers
Transmission modification is illegal. Traffic regulations do not allow modifications to a vehicle's power and transmission systems, otherwise, it will fail the annual inspection. Below is a detailed introduction about vehicle transmissions: Introduction: A car transmission is a set of gear-shifting devices used to coordinate the engine's speed and the actual driving speed of the wheels, ensuring the engine performs at its best. The transmission can create different gear ratios between the engine and the wheels during driving. Function: The engine's output speed is very high, and the maximum power and torque occur within a certain speed range. To achieve the engine's optimal performance, a transmission system is necessary to coordinate the engine's speed and the actual driving speed of the wheels.
