Are there any known problems with the BMW M3 gearboxes (2002-2006)?

The manual gearbox on the E46-generation M3 is fine, as long as it’s not been abused and the car in general has been properly looked after. The SMG on the other hand is a nightmare of potential problems. Quite aside from being awkward and jerky to use even when it’s in perfect health, it develops frequent problems with the hydraulic pumps, solenoids and electrical relays. Avoid the SMG at all costs.
