How to recognise a gearbox malfunction on a BMW 8 Series?

If your vehicle is fitted with a manual gearbox and you have difficulty shifting gears, this may indicate a problem with the clutch or gearshift mechanism. Similarly, unusual noises when shifting g ears may indicate timing problems or worn internal components.
If your vehicle is fitted with an automatic gearbox, abrupt or rough gear changes may indicate a problem with the transmission fluid, torque converter or internal components.
