When your 8 speed box starts slipping, holding gears, or banging through the shifts, a brand new dealership replacement will easily empty your bank account. This is the honest alternative for the grafters and purists who just want to get their vehicle back on the road without paying a premium.

This is a genuine second hand ZF 8HP50 automatic gearbox (Factory Designation: GA8HP50Z), carrying the BMW part number 8678661. It is a direct rear wheel drive fitment for various modern BMWs, primarily the F20 1 Series and F30/F31 3 Series equipped with the B47 2.0d diesel engine.

As with every heavy part that hits Marian’s bench, this unit has been thoroughly checked over. The bellhousing is structurally sound, the torque converter seating is clean and the factory identification tags are fully intact. We supply this unit as removed, it has not been opened or tampered with.

To guarantee longevity, we strongly advise having your mechanic replace the fluid pan/filter with genuine ZF Lifeguard fluid and running the proper software adaptations once it is bolted to your engine.
