Chrysler says its 8-speed transmissions will save 700 million gallons

Chrysler Group's TorqueFlite eight-speed transmission could be earning some serious green bragging rights if the company's projections are correct. The recently widely proliferated automatic gearbox, which is now in more than a million vehicles around the world, is poised to save drivers an estimated 700+ million gallons of fuel over the vehicles' lifetimes (an expected cost savings of $2.5 billion). In addition, Chrysler expects a reduction in CO2 emissions by more than six million metric tons. According to Chrysler, and depending on the vehicle, the TorqueFlite can improve fuel economy. The TorqueFlite autobox features particularly close ratios from fifth to eighth gear (see the press release below for the specific numbers), and uses low-viscosity fluid that doesn't need to be replaced. Transmission software adapts to the driving situation to optimize efficiency based on driver behavior, temperature, grade, stability control, and longitudinal and lateral acceleration. The TorqueFlite is capable of handling a variety of duties. As evidenced by the wide range of vehicles Chrysler Group has seen fit to equip with the eight-speed transmission, the TorqueFlite is capable of handling a variety of duties. Since its 2012 introduction, the TorqueFlite has gone from performing cog-swapping duties in Dodge Charger and Chrysler 300 models equipped with the 3.6-liter Pentastar V6 to changing gears in vehicles such as the Pentastar- and Hemi-powered Dodge Durango, Jeep Grand Cherokee and even the Ram 1500 EcoDiesel. For the 2015 model year, the eight-speed is finding its way into even more vehicles with the addition of a third version. In addition to the American-made TorqueFlite 845RE and 8HP70, the new 8HP90 will be manufactured in Saarbrucken, Germany. The 8HP90 is designed for higher torque loads, making it ideal for high-performance vehicles like the 2015 Dodge Challenger SRT Hellcat. The already-in-use 8HP70 will expand its duties to be used in 2015 Hemi models such as the Dodge Charger, Challenger, and Challenger SRT8. You can see the list of those benchmarks in Chrysler's press release below.

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.

FCA recalls 1.1 million vehicles worldwide due to confusing shifter

Fiat Chrysler is recalling 1.1 million vehicles worldwide to address the problematic shifter used on cars with eight-speed automatic transmissions. The issue is that the console-mounted shifter acts like a rocker switch and always returns to the middle position after moved. This has been deemed confusing to drivers – confusing enough to cause some to exit their vehicles without first selecting Park and leading to the car rolling away. FCA says 41 injuries are related to the shifter problem, and no evidence of equipment failure has been found. The company will enhance warning chimes and alter the shift strategy, meaning alert messages will be displayed in case the driver door is opened while the engine is running. With the door open, the transmission will prevent the car from moving even if Park is not selected. The affected vehicles are certain model-year 2012–2014 Dodge Charger and Chrysler 300 sedans, as well as model-year 2014–2015 Jeep Grand Cherokee SUVs, an estimated 811,586 US vehicles in total. The recall also affects 52,144 vehicles in Canada, 16,805 in Mexico, and 248,667 vehicles elsewhere. The shifter is used with ZF-designed and ZF-built eight-speed automatic; Audi uses a similar shifter setup in some of its vehicles, including the current-generation, which predated Chrysler's use of it. Chrysler uses a different, a rotating-dial-type shifter on eight-speed-equipped Rams. The company moved away from the problem shifter design in 2015 for the Charger and 300, and the Grand Cherokee's shift lever was modified for 2016. Owners of affected vehicles will be notified of the recall when service is available. Fiat Chrysler urges customers to follow the instructions in the vehicle's owner's manual in the meantime.
