Motor Trend February 2006
Porsche is reportedly ironing out problems with its new twin-clutch transmission. Insiders say engineers are unhappy with the shift quality of the new tranny in full auto mode. The problem now is that Porsche was banking on the PDK to serve double duty for those customers who wanted an automatic and so didn't bother to adapt ZF's smooth six-speed auto-manual, which is why the 911 automatic [and the Cayman] are still five speeders. The irony, of course, is that Porsche was first to prove out the twin-clutch concept, using it in its sports racers during the 1980s.
