Reconditioned BMW Série 1 3.0 Gearbox – 6-Speed Manual – Ref. GS6-45BZ-HAJ

Reconditioned BMW Série 1 3.0 Petrol Gearbox – GS6-45BZ-HAJ

This reconditioned gearbox is specifically designed for the BMW Série 1 3.0 Petrol, fitted with the N52B30 engine (2996 cm³), and carries the reference GS6-45BZ-HAJ. Reconditioning follows a rigorous process: the gearbox is fully stripped down, every component is cleaned and inspected both visually and dimensionally, and any gears, synchros, bearings or seals showing signs of wear are systematically replaced. The unit is then reassembled to manufacturer tolerances before a final bench test. This exacting standard ensures performance that meets BMW's original specifications for the GS6-45BZ-HAJ reference.
