Ford and General Motors signed an agreement five years ago to jointly develop nine- and 10-speed automatic transmissions as a way to lower costs and achieve higher fuel economy amid tightening federal rules. But now, Ford is saying no thanks to the nine-speed box developed by its crosstown rival.
Chrysler's latest commercial for the new 300 looks to tout the automaker's new eight-speed automatic transmission for 2012, which offers up to 31 miles per gallon on the highway when paired with the 3.6-liter Pentastar V6 engine. That's commendable mileage for a large, rear-wheel-drive sedan, and Chrysler deserves credit for making it happen.
Did your favorite brand just move to six-speed automatics? Are you already cruising along happily in seventh gear or perhaps you're enjoying the scenery with your transmission lazily churning in eighth. Well move over because ZF is getting ready to produce a nine-speed automatic gearbox.
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 Transmiss

How many gears are enough? While it seems that six-speed automatic transmissions are just now becoming the de facto standard in most circles, Mercedes-Benz has been working with seven ratios for a while now and Lexus did its German rival one better by designing its own eight-speed. Not con
Last year, Lexus became the first automaker to introduce a production eight-speed automatic transmission in the latest LS460. Recently, German transmission manufacturer ZF announced a new eight-speed of its own which is claimed to provide a 14-percent boost in fuel efficiency compared to a five-speed. It looks like Audi and BMW will likely be the first to directly challenge Lexus when they start using the ZF. Audi may be first out of the gate in 2009, with eight-speed installations in the A8, Q7
In the name of increased efficiency, and quite possibly playing the game of automotive one-upmanship, luxury automakers such as Mercedes Benz, BMW and Lexus have been adding more and more gear ratios to their automatic transmissions. By allowing a computer to choose the most appropriate ratio for any given scenario, the vehicle's engine is required to only make as much power as absolutely necessary, potentially saving fuel in the process. ZF, one of the largest transmission makers in the world,
