Explains the building blocks of the 3-speed unit: how a planetary gear train multiplies torque, reverses rotation or locks up for direct drive, and why it is compact. It then describes the fluid coupling and torque multiplier, which gives 1.3 times engine torque in first and reverse, the sprag clutch, and how the two planetary units, front clutch, neutral clutch, reverse cone and overrun band relate. A cross-section drawing of the transmission is on page 10.

What this section covers

  • Planetary gear train operation
  • Fluid coupling and torque multiplier
  • Sprag clutch
  • Neutral clutch, reverse cone and overrun band
  • Relationship of units
