What are the functions of transmission system?
The function of any transmission is transferring engine power to the driveshaft and rear wheels (or axle halfshafts and front wheels in a front-wheel-drive vehicle). Gears inside the transmission change the vehicle’s drive-wheel speed and torque in relation to engine speed and torque.
What is transmission and its function?
A transmission is a machine in a power transmission system, which provides controlled application of power. … The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process.
