Gearbox synchromesh and selection wear
SeriousGearbox & TransmissionEarly 550 Maranellos can suffer difficult gear selection, particularly into first, third and fifth, and wear of the second and third gear synchromesh, causing crunching or reluctance to engage even from cold. A full rebuild is expensive and some internal parts are no longer readily available, which can make the work very costly. Test every gear when cold and warm during the test drive; any crunch or missed shift should be investigated by a specialist before purchase.
