Dual clutch transmission... sounds complicated. And it is. Case in point: BMW's
new DCT on its latest-generation M3. This new transmission from Munich is so complicated that apparently even BMW couldn't get it right the first time, so they're issuing a recall. The problem, as concluded by the National Highway Traffic Safety Administration
, is that under hard braking the transmission's software is prone to initiate a multi-stage downshift, which could cause the car to stall. The solution, however, should be fairly simple, as BMW is asking all owners of 2008 or 2009 M3s equipped with the DCT (about 2,500 in the United States) to come in for a software update, free of charge, at their local dealership
. After the software update, M3 owners can perform all the panic stops they want in smooth-shifting bliss.
The official recall notice can be viewed on the NHTSA website. Thanks for the tip, TKE!
