Chrysler Touts Fuel Savings of 8-Speed Automatic Gearbox

Chrysler Group LLC estimates that its growing use of 8-speed automatic transmissions will enable the company's vehicles to reduce gasoline usage by 700 million gallons over their service life.

The company says the improved fuel efficiency also will cut carbon dioxide emissions from those vehicles by more than 6 million metric tons.

Chrysler has installed its TorqueFlite 8-speed gearboxes in more than 1 million vehicles worldwide since the transmission debuted in the 2012 model year.
