Do you know your powertrain and transmission system transmits engine power to the vehicle's wheels and multiples engine torque to accelerate the vehicle? Nearly 100 years ago cars had two- or three-speed manual transmissions that required an expert hand to operate smoothly. They were noisy, rudimentary systems compared to today's modern powertrain and transmission systems. The vehicle's powertrain and transmission system transmits engine power
to the vehicle wheels. It provides for multiplication of engine torque (or twisting force) to accelerate the vehicle from a stop, or for carrying heavy loads in the case of trucks. The system also allows for engine speed reduction at cruising speeds to save fuel and reduce noise. Key components of the system include: - Transmission or Trans-axle - Transfer Case (four-wheel-drive or all-wheel-drive) - Propeller Shaft (drives the rear axle) - Drive Axles (drives the wheels) - Clutch (manual shift) - Torque Converter (automatic shift) The various components are subject to wear and may malfunction; this can cause abnormal noise, loss of drive or gear ratio, vibration, or other driveability concerns. This may also be accompanied by an illuminated or flashing check engine light or gear range indicator. Ignoring a indicator light can further damage the system or other components.
