Transmission and drivetrain: “I own a 2009 Porsche carrera convertible with pdk transmission. In stop and go traffic and car shifts into neutral for a split second or two before engaging into first gear. My car only has 4,300 miles and this problem seems to be getting worse as time goes on. Porsche told me that they are aware of the problem with no solution at this time. This situation is very dangerous when I am waiting in an intersection wanted to make a left turn and then when I finally it is clear to turn the car would shift into neutral for about a second before engaging into first gear.”
