Instead of numerous helical compression springs, Slotted Disc Springs are used as piston return springs in clutches of modern automatic, continuously variable and dual-clutch transmissions. In addition, when used as contact or damping springs, Wave and Disc Springs improve shifting comfort. The transmission length can be shorted by using disc springs in automatic transmissions and the weight can be reduced by 5%.

Transmission Shafts, such as input shafts, sun shafts, main shafts or adapter shafts transfer and step up torque and engine speed between the clutch components in the transmission. Intermediate and Drive Shafts transfer the power from the transmission to the drive wheels. By substituting shafts of solid material with tubular shafts, the weight can be reduced by 30% or more per shaft.
