We'd heard that problems with the Tesla Roadster's transmission were going to lead the company to ship the cars with "temporary" transmissions, but our friends over at AutoblogGreen were recently contacted by Tesla and told that while the company is indeed considering shipping cars with a different tranny than originally planned, they won't be designed to fail, as we'd originally heard. Rather, it'll be a single-speed transmission that won't allow the all-electric hot rod to run as fast as the planned two-speed version. Tesla still plans to swap out the units for the real deal when they're finally strong enough to handle the electric's massive torque, but at least now when Tesla owners are stranded by the side of the road they'll just need an extension cord, not a whole new transmission.
