ShiftFX Efficiency
Power In = Power Out
Standard transmissions are recognized as being the most efficient way of delivering power to the wheels of a vehicle. Drivetrain efficiencies on the order of 96 to 98% are easily achievable. Historically, standard transmissions were only available with manual control which led to the term "manual transmissions". Consumer demand for vehicles that were easy to operate allowed other transmissions to be developed. Unfortunately these new transmissions suffer from reduced fuel economy due to drivetrain inefficiencies and increased weight.
| Alternative Transmission | Disadvantage |
| Automatic | Torque Converter Losses |
| CVT (Continuously variable transmission) | Belt Friction Losses |
| Hydro-mechanical Pump | Hydraulic Losses |
Power In = Power Out
Other power plants can benefit from using a standard transmission. For the emerging class of electric vehicles the inclusion of a multi-gear transmission can increase top speed while extending battery life. The electric motor drive's ability to start from a standstill means a clutch is not required, making the transmission much more compact and economical.
