Your car's drivetrain is a vital power-transmitting component ,and
key to dependability. It's responsible for transmitting the flow of
power from the engine to the wheels. The components include the clutch,
torque converter, transmission, driveshafts (or axle shafts in front
wheel drive), Ujoints, CV joints, differential and axles.
Most motorists take these components
for granted until something goes wrong. That "something" can
range from leaks or strange noises to shifting problems to total
failure. If you do a lot of stop-and-go-driving, tow a trailer or
otherwise subject your vehicle to unusual service, check your owners
manual for recommendations. With regular checks and maintenance you
can expect two bonuses: a more dependable car, as well as fewer and
smaller repair bills.
