I've heard that the sensors (ones that tell the car what gear is selected) in the transmission are "regular maintenance" items that need to be changed every 10k miles or so. I can't seem to find any threads on this and am wondering if this is actually needed? It's the same transmission as the street going 458 correct? I know there was an early issue of wire routing in the gearbox that got fixed, but these sensors are apparently a wear item that just need changing. Can someone confirm this? If so, is this strictly a dealer job or could a handy person DIY it? And if so, any links to parts/instructions? Thanks!
