Automakers hope to save millions of dollars with joint development

Ford and General Motors have announced that they have teamed up to jointly develop a new generation of advanced 9- and 10-speed transmissions that will be used in cars, crossovers, SUVs, and trucks.
The automakers say that the new transmissions will increase both performance and fuel economy. Engineering and development work for the transmissions is currently underway.

“Engineering teams from GM and Ford have already started initial design work on these new transmissions,” said Jim Lanzon, GM vice president of global transmission engineering. “We expect these new transmissions to raise the standard of technology, performance and quality for our customers while helping drive fuel economy improvements into both companies' future product portfolios.”

Automakers need every edge they can get to meet the looming federal CAFE guidelines set to go into effect over the next several years. With a greater number of gear ratios available in the transmission, the engine can operate at more efficient RPMs, which in turn leads to improved fuel economy.
Some industry analysts believe that a nine-speed automatic transmission could increase fuel economy by five to ten percent compared to the same vehicle using a six-speed transmission.
The two companies have collaborated on transmission technology in the past. Ford and GM previously collaborated to build a six-speed transmission for front-wheel drive cars. Ford currently uses the six-speed transmission and vehicle such as the Fusion and Edge. GM uses the transmission in the Malibu and Cruze among others.
Chrysler is currently using an eight-speed automatic transmission in some of its automobiles, including its popular line of trucks.

RE: Continuously Variable Transmission (CVT)

I was thinking the same thing as I read this article. Provided we keep adding gears why not just let it vary the whole time to make it more efficient. My '11 Nissan Rogue has a CVT and it seems fine enough. About 180hp, while not great, gets my AWD vehicle moving adequately. I do have to admit though, it does whine a lot at anything past 2.5k rmps.

You will never see a CVT capable of handling 500+ whp. For that matter, I don't if any CVT has ever been certified to a towing capacity of anything larger than a bicycle.

I'm very happy to see 8+ speed transmissions. I feel that the time is long overdue, especially considering the wake of the oil crises during the 1970's. From my perspective, DCT's are the only other technology worth pursuing. CVT's and rowing-machines belong in the garbage bin.

Well, that's just, like, your opinion, man.

Seriously though, CVTs work very well for certain applications. It's a stupid opinion that blindly disregards the benefits of any given technology in order to disparage it.

Love it.

My '06 murano has a CVT and it's rated for towing up to 3,500 lbs.

That's a LOT of bicycles. A whole trailer full.
