CHRYSLER’S TORQUEFLITE 8-SPEED TRANSMISSION BRINGS
The advanced-technology automatics – first of their kind ever made available to mainstream brand customers – now are powering more than one million vehicles worldwide, said Mayne. And their combined effect is staggering, he said. Over their lifetimes, vehicles equipped with TorqueFlite eightspeed transmissions are projected to save their owners more than 700 million gallons of fuel, compared with their predecessors that featured five- or six-speed automatics. That quantity of gasoline is worth approximately $2.5 billion at the pump, based on current fuel-price forecasts. The effect will also reduce combined CO2 emissions by more than six million metric tons, Mayne said.
1950s,” Mayne said. “The technology may have changed, but what TorqueFlite represents – superior technology giving superior performance and greater efficiency – that hasn’t changed, so we used the name again.”
TorqueFlite eight-speed transmissions in model-year 2014 vehicles also contribute to 19 Chrysler fuel-economy or driving- range benchmarks across four vehicle segments. “This is precisely the kind of impact we targeted with the TorqueFlite program,” said Jeffrey Lux, vice president and head of Transmission Powertrain
Starting in model-year 2015, the TorqueFlite 8HP70 transmission can be paired with Hemi-equipped Dodge Chargers, Challengers and Challenger SRTs, Lux said.
When the TorqueFlite 8HP45/845RE made its debut in model-year 2012, the transmission was mated exclusively to Chrysler’s award-winning 3.6-liter Pentastar V6 in the Charger and Chrysler 300 lineups. Since then, the TorqueFlite 845RE and 8HP70 have migrated, respectively, to Pentastar- and HEMI-powered versions of the Dodge Durango, Ram 1500 and Jeep Grand Cherokee lineups. The 8HP70 also serves EcoDiesel versions of the 1500 and Grand Cherokee.
Lower viscosity transmission fluid is used to improve operating efficiency and fuel economy, especially during cold environments or vehicle start-up, Lux said. The TorqueFlite also is “fill-for-life.” That means, Lux said, that it never requires oil changes, when subjected to normal driving conditions.
