GM will put 8-speed in its big pickups: More gears could boost fuel economy

摘要

General Motors will offer a new eight-speed automatic transmission in the next generation of full-sized pickups and SUVs it plans to launch in early 2013. GM is expected to begin producing its homegrown transmission at its Toledo powertrain plant by the end of 2012 for use in trucks, three people familiar with the plans said. Two sources said the same gearbox eventually will be offered on rear-wheel-drive Cadillacs, such as the ATS compact sedan GM is unveiling this week at the Detroit auto show.
