What is a transmission?

The transmission works in conjunction with the engine to ultimately provide power to your car’s wheels and tires. Automatic Transmissions in European vehicles contribute a significant role in the overall performance.

What does a transmission do?

A transmission or a transaxle keeps the engine’s output optimally matched to the speed and load conditions via multiple gears, much like your bicycle’s speed selectors. The transmission will transmit engine power to the rear axle on rear-wheel-drive cars, or the front axle on front-wheel-drive vehicles. The automatic transmission fluids may be unique to each manufacturer, and you cannot substitute a different type of liquid. The transmission fluid serves multiple purposes: it cleans, cools, lubricates, transmits force, and pressure, which makes it all work. Think of it as the blood for the heart.

Typical Wear on a transmission can be determined by:

  • Condition of the transmission fluid
  • Driving habits
  • Towing or excessive loads
  • Operating conditions
  • Frequency of regular maintenance


  • Slipping
  • Hesitation
  • Bucking
  • Difficulty shifting
