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)

Thanks. That's a very promising technology that appears ready for manufacture in large numbers and for many applications. I see it will first be used for transmissions in heavy equipment and urban trucks/buses, as a variable drive supercharger for gasoline and diesel engines, and as a kinetic energy recovery system for trucks/buses.
I hope that a car manufacturer decides to use it. The IVT certainly looks like a better mousetrap.

"I hope that a car manufacturer decides to use it."
Well, several have taken a very close look at the use of the IVT, particularly as part of an M-KERS (Mechanical KERS system ) including Volvo:
