4/3/2007. 2005 Mercedes Benz slk 350. Consumer states that occasionally when the vehicle is in neutral at a stop light it is extremely hard to go into first gear. The consumer stated he sometimes has to apply additional pressure on the stick, and when doing so the stick goes into reverse. The problem happened intermittently, therefore, the dealer was unable to duplicate the consumers complaint. A TSB had been issued for the exact problem the consumer was experiencing.
