At two separate events recently, ZF publicly confirmed rumours that it is developing a new 8-speed automatic transmission, for launch in 2010. This follows the introduction by Mercedes-Benz of its 7-speed W7A-700 in 2003, and more recently the Aisin TL-80SC (=Toyota/Lexus AA80E) 8-speed automatic, which is fitted in the Lexus LS460 [250L] writes Chris Guile, powertrain analyst at CSM Worldwide.
