Drivetrain
A drivetrain is not actually a solitary part of your car – it's a group of drivetrain parts that collaborate with the engine to move the wheels and various parts of the car to drive it into motion. These parts usually include the transmission, differential, driveshaft, axles, CV joints, and the wheels.
