Jeep still working to improve Cherokee's 9-speed auto

Fiat Chrysler is hoping an upcoming software update will stem the tide of consumer complaints surrounding its nine-speed automatic transmission. Owners of the 2014 Jeep Cherokee have reported a number of problems on the National Highway Traffic Safety Administration's SaferCar.gov website, since the new model and its troubled gearbox arrived way back in October 2013. The software update is "intended to keep the vehicle performing as intended, and to prevent durability issues from occurring in the future," an FCA spokesperson told Automotive News, and will be available to owners of both the 2014 to 2015 Jeep Cherokee and the 2015 Chrysler 200, which also uses the 9AT. While FCA will be notifying consumers of the update, owners can also request the software reflash if they happen into their dealer before then. Despite the widely documented problems with the transmission, the only complaints on NHTSA's website relate to the 2014 Cherokee – neither the 2015 Jeep nor the 200 have received any complaints. That bodes well as FCA prepares to begin deliveries of the 2015 Jeep Renegade and launch the Fiat 500X, both of which pair the 9AT with the 2.4-liter Tigershark four-cylinder. "We have had to do an inordinate amount of intervention on that transmission, surely beyond what any of us had forecast," FCA CEO Sergio Marchionne told Automotive News. "There are things that we have done – that we continue to do. Our proactive customer care intervention has actually increased in intensity on these vehicles in 2014, especially in the second half." What's fascinating about the 9AT's problems are that they haven't been the fault of manufacturer ZF, but have related to software that wasn't "mature" and had "teething problems," Marchionne has said previously, AN reports. With the lack of criticism for the 9AT in 2015 models and this pending software update, though, here's hoping that FCA has finally figured out its fuel-sipping gearbox. Related Video:

Chrysler recalling nearly half a million Durangos and Grand Cherokees

Rule number one of public relations – save the bad news for Friday. Fiat Chrysler has adhered to that, announcing today that it'd be voluntarily recalling 467,480 SUVs. This latest recall could actually be thought of as a continuation of a September 2014 recall, relating to the fuel-cell relay. In that case, some 188,723 Dodge Durango and Jeep Grand Cherokee CUVs from model year 2011 were recalled. And this time, it's the Durango and GC in trouble again. FCA is adding crossovers from model years 2012 and 2013 to the fuel-pump recall, although only diesel-powered Jeeps with the 3.0-liter V6 that were sold outside of North America are affected this time around. As with the previous recall, deformities in the fuel-pump relay, which could affect its functioning. In most cases, FCA reports that the affected vehicles simply won't start, although they also could be prone to stalling. A new relay circuit will be installed that promises increase durability. Of the 467,480 vehicles being recalled, 338,216 were sold in the US market, 18,991 went to Canada and 10,829 were shipped south of the border, to Mexico. Outside of the NAFTA region, FCA is recalling 99,444 vehicles. No injuries or accidents have been associated with this recall. Statement: Fuel-Pump Relay February 27, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 467,480 SUVs worldwide to install new a relay circuit that improves fuel-pump relay durability. FCA US engineers have determined a condition identified in a previous investigation may extend to additional vehicles. The previous investigation, which led to a recall, traced a pattern of repairs to fuel-pump relays that are susceptible to deformation. This may affect fuel-pump function, preventing a vehicle from starting, or leading to engine stall. Of the two scenarios, the no-start condition is the more common. FCA US is unaware of any related injuries or accidents. The fuel-pump relay is located inside the Totally Integrated Power Module (TIPM), which also helps manage other vehicle functions. None of these other functions, including air-bag deployment, is affected by the fuel-pump relay. The new campaign affects an estimated 338,216 vehicles in the U.S.; 18,991 in Canada; 10,829 in Mexico and 99,444 outside the NAFTA region. Covered are model-year 2012 and 2013 Dodge Durango full-size SUVs and non-NAFTA 2011 Jeep Grand Cherokee mid-size SUVs equipped with 3.0-liter diesel engines.

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.
