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.

What's really going on with the 2014 Jeep Cherokee's transmission issues?

On September 23, Automotive News reported that Chrysler had idled the second shift workers it hired just five weeks prior at its Toledo Assembly Complex to build the 2014 Jeep Cherokee. At the time, Chrysler said it had "built the critical number of vehicles we need to stock dealerships once containment is released" and did not want "to put additional strain on our logistics partners ... upon release." That reasoning was not only unusual, it didn't seem to make sense.
It appears the center of the nine-speed issue is software, not hardware.
That same day, the Detroit News ran a piece claiming workers at the Toledo factory said the halt was due to issues with the Cherokee's transmission. It put the number of already-built Cherokees needing fixes at 1,000 and said that some of the workers not laid off had been instructed "to take the Jeep on long test-drives." That made more sense. Three days later, on September 26, Automotive News reported that the 500 workers laid off had been reinstated, with engineers "speeding repairs on the SUV's powertrain software." The AN piece didn't put a number on how many units are being fixed, but it did say that 12,000 have been built and are awaiting delivery to dealers. The best it could say about when dealers will get them, however, is that "progress on a fix is being made. It's unclear when shipments to dealers will start."

FCA's shifter fiasco proves novel gear selectors are a bad idea

What's wrong with PRNDL? Why are automakers trying to overly complicate the simple task of selecting gears? If there's any lesson to learn from the recent news that NHTSA is investigating 853,000 Fiat Chrysler vehicles over its problematic gear selectors, it's that the trend of fancy shifters needs to stop. Now. Last year, NHTSA opened an investigation into Jeep Grand Cherokee models, and has now expanded this probe to include the 2012-14 Chrysler 300 and Dodge Charger. The problem? The shifter – assembled by ZF – is confusing for many drivers. "Testing ... indicates that operation of the (electronic) shifter is not intuitive and provides poor tactile and visual feedback to the driver, increasing the potential for unintended gear selection," a NHTSA document states. More than 100 crashes and over a dozen injuries are linked to this problem, according to The Detroit Free Press. To us, the problem isn't just limited to FCA. These unnecessarily novel gear selectors are spreading like wildfire across the industry. Honda and Acura use a weird pushbutton setup. Lincolns have buttons on the dashboard. Jaguar's shifter electronically raises out of the center console. Mercedes uses a stalk with up-for-Reverse, down-for-Drive, push-for-Neutral arrangement. And what the hell is BMW thinking with its M cars? FCA has since abandoned the confusing shifters in question. The 300, Charger, and Grand Cherokee now use the rotary shift dial that's quickly proliferating across the company's brands. Simplistic gear selectors might not be sexy, but no one ever complained about not being able to find the right gear in a Hyundai Sonata. What's most interesting is that this NHTSA investigation could push FCA – and possibly other automakers – to redesign vehicle functions that otherwise operate as designed. Just because most people will never have a problem putting a Dodge Charger in Reverse doesn't mean there isn't a flaw with the design. But perhaps a more simplistic solution – good ol' PRNDL – would have prevented these issues from the start.
