Today’s Automatic Transmission Fluids: a Study in Complexity

transmissionarevThe step-type automatic transmission is one of the most sophisticated components in today’s motor vehicles. Using a hydraulic clutch, it transfers torque from the engine through a series of gears, and shifts between them so smoothly that people in the vehicle will barely feel the shifting.

In order to work smoothly, the design of the transmission must take into consideration many aspects of the vehicle – including power, use, speeds and loads. What’s more, vehicle manufacturers must look at the transmission as a vital component in their search for fuel economy to meet new efficiency standards all over the world. The result is a transmission that’s typically optimized to the vehicle and market it serves. Continue reading
