The human body runs on various systems. We have our circulatory system, skeletal system, respiratory system, and so on. We need each system to work properly to remain healthy. Our vehicles are the same. They contain a series of systems that work together to keep it functioning properly. Each system needs to be properly maintained and taken care of.

This is the tenth, and final post in a series of blogs we are sharing about the various vehicle systems and their function. Please also see:

Whether it’s automatic or manual, the transmission plays a major role in the overall performance of the vehicle. It works with the engine to provide power to the vehicle’s wheels.

Parts of the transmission system include:

  • Automatic transmission/transaxle or manual transmission/transaxle
  • CV joint/axle/boot
  • Half shaft
  • Torque converter
  • Transfer case (only in some all-wheel-drive or four-wheel-drive vehicles)
  • Transmission fluid/dipstick
  • Universal joints

The transmission, whether it be automatic or manual, is responsible for keeping the engine’s productivity optimally matched to the speed and load conditions. The torque converter, connected to the automatic transmission/transaxle input shaft, connects, multiplies and interrupts the flow of engine torque into the transmission. CV or universal joints connect to the driveshaft to transmit output power from the transmission to the front axle on front-wheel-drive cars or the rear axle on rear-wheel-drive cars.  These joints allow the drive shaft to work at an angle. The transmission fluid cleans, lubricates, transmits force, transmits pressure, inhibits varnish buildup and protects the transmission.


Driving habits, towing or excessive loads, operating conditions, condition of the transmission fluid, and the frequency of regular maintenance can all influence the amount of wear on the transmission system. As one of the most complicated components of your vehicle, the transmission can be difficult to diagnose.  Sometimes what appears to be a transmission problem is not a related to the transmission at all!
