Dual-clutch transmissions in plant

Last week, in the midst of Detroit’s first days seeking relief in Chapter 9 of the bankruptcy code, Automotive News contributor Larry P. Vellequette penned an editorial suggesting that American car companies raise the white flag on dual clutch transmissions and give up on trying to persuade Americans to buy cars fitted with them. Why? Because, Vellequette says, like CVT transmissions, they “just don’t sound right or feel right to American drivers.” (Note: In the article, it’s not clear if Vellequette is arguing against wet-clutch and dry-clutch DCTs or just dry-clutch DCTs, which is what Ford and Chrysler use.) The article goes on to state that Ford and Chrysler have experimented with DCTs and that both consumers and the automotive press haven’t exactly given them glowing reviews, despite their quicker shifts and increased fuel efficiency potential compared to torque-converter automatic transmissions.

Autoblog staffers who weighed in on the relevance of DCTs in American cars generally disagreed with the blanket nature of Vellequette’s statement that they don’t sound or feel right, but admit that their lack of refinement compared to traditional automatics can be an issue for consumers. That’s particularly true in workaday cars like the Ford Focus and Dodge Dart, both of which have come in for criticism in reviews and owner surveys. From where we sit, the higher-performance orientation of such transmissions doesn’t always meld as well with the marching orders of everyday commuters (particularly if drivers haven’t been educated as to the transmission’s benefits and tradeoffs), and in models not fitted with paddle shifters, it’s particularly hard for drivers to use a DCT to its best advantage.

Finally, we also note that DCT tuning is very much an evolving science. For instance, Autoblog editors who objected to dual-clutch tuning in the Dart have more recently found the technology agreeable in the Fiat 500L. Practice makes perfect – or at least more acceptable.

Report: Chrysler pulling ahead production of eight-speed transmissions

Filed under: Plants/Manufacturing, Chrysler

Chrysler transmission plant

Chrysler is getting serious about its eight-speed transmission plans as evidenced by a new report by TheDetroitBureau.com saying that Auburn Hills plans to pull ahead its production schedule. It takes money to make things things like this happen, and Chrysler has announced it is investing $85 million into its Kokomo Transmission Plant in Indiana. That $85M will get added to a rather large pile of cash because Chrysler has already announced an investment amount of $843 million for its various Kokomo facilities.

The eight-speed was originally slated for production at Chrysler’s Indiana Transmission Plant I, but the move to Kokomo allows ITPI to focus on a new front-wheel drive transmission.

The National Highway Traffic Safety Administration announced on its website that Honda is recalling 585 2010 Element crossovers equipped with a manual transmission. The vehicles in question may have an improperly set cable that connects the shift lever to the transmission, an issue that could lead to anything from a major inconvenience for owners to the increased risk of an accident.

This defect may cause the gear shift lever to interact improperly with the transmission, leading to the wrong gear being selected. Affected vehicles could also get stuck in neutral, lose the ability to shift into reverse or fail to allow the key to be removed from the ignition.

Owners of the affected vehicles can bring their Element to the local Honda dealership for a free repair. Some owners have already been contacted about this issue, but all 585 will receive a notice from Honda by August 9. Element owners with questions or concerns can contact Honda at 1-800-999-1009. Hit the jump to read over the NHTSA press release.

Double-clutch transmissions graduate to the world of commercial trucks

Fuso Duonic DCT

Dual-clutch transmissions have become increasingly popular in small cars and have even appeared in high-performance machines like the Porsche 911 and Bugatti Veyron. Now, Mitsubishi Fuso has become the first commercial truck maker to offer one of these fancy new gearboxes in a hauler.

The new six-speed M038S6 “Duonic transmission” features wet clutches and incorporates the ability to creep in traffic for smoother operation. Although Duonic-equipped trucks will probably be driven mostly in fully-automatic mode, the transmission can also be manually shifted. Mitsubishi Fuso is 85-percent owned by Daimler, with the remainder being held by Mitsubishi.
