Yes, Logitech claims that the two are incompatible, but the Logitech g29 software recognizes the g27 shifter as the g29 shifter. Sadly, that renders the macro keys useless because you can no longer customize them. But the accutioal shifting part is 100% glitch free, meaning that if you switch to the second gear in real life, it won't go the the third in the game. :)
