Does Replacing the Entire Transmission Count as a Major Overhaul?
1 Answers
Disassembling a car's transmission is considered a major overhaul. The functions and working principles of a transmission are as follows: Functions of a Transmission: To alter the transmission ratio, expanding the range of torque and speed variations in the drive wheels; enabling the vehicle to reverse while maintaining the engine's rotation direction; it is a mechanism that modifies the speed and torque from the engine, capable of fixing or changing the transmission ratio between the output and input shafts in stages. Working Principle of a Transmission: It achieves speed and torque variation through hydraulic transmission and gear combinations. The torque converter is located at the forefront of the hydraulic automatic transmission, mounted on the engine's flywheel. Its function is similar to the clutch in a car, and it can automatically and continuously adjust the transmission ratio and torque ratio within a certain range based on changes in the vehicle's driving resistance, providing a certain degree of speed reduction and torque increase.
