5HP19 Clutch Drum, used and ready to install. Fits the 5HP19. Ships fast from the USA.
A BMW with the ZF 5HP19 that slips when pulling away in Drive, engages late, or flares in the lower gears may have a tired forward clutch drum. This is a used, original BMW 5HP19 loaded forward clutch drum: the drum comes with its clutch pack installed rather than as a bare shell, so you are not sourcing frictions and steels separately to get the unit back together.
ZF builds the 5HP19 input assembly as a stack of three clutches on the input shaft, labeled A, B and E in the factory manual. Cylinder A meshes directly with the input shaft, so this drum spins at turbine speed and hands power to the gearset when clutch A applies. Inside it is a piston with three O-rings, a cup spring held by a split stop ring, and the disc pack, closed with a final disc and snap ring. Oil reaches the piston through the input shaft, sealed by rectangular-section rings and an O-ring, so the shaft rings and the drum hub have to be in good shape for the clutch to hold.
Not every 5HP19 slip is this drum. A Vehicle Service Pros bulletin traces a 2-3 flare or loss of third and fourth with BMW code 46 to a different part, the F clutch drum, where a shifted sleeve lets a sealing ring leak; that one is fixed with a new F drum, not a forward drum. Valve body faults cause harsh or soft engagement too. Check pressure with our line pressure guide, note exactly which gears slip, and use shift flare vs slip to read the symptom. A slip that is present from the first engagement in Drive points at this drum and its seals.
This drum is listed as original BMW 5HP19, the version used in the E46 3 Series and E39 5 Series era. The Audi, VW and Porsche 5HP19FL and FLA units share the family name but differ in layout, so compare your old drum to the photo before ordering, or send us your year, model and VIN to confirm. Other 5HP19 hard parts, including the 5HP19 planetary, are listed in the shop.
The ZF manual calls for new O-rings, sealing rings and gaskets on any repair, with every ring coated in white petroleum jelly before assembly. Check the clutch A clearance with the snap ring installed; ZF's test value is 3.09 to 4.58 mm. Air-check the piston through the feed holes before the assembly goes in. If the old drum burned its frictions, plan on the 5HP19 master rebuild kit for seals and the other packs, and inspect the 5HP19 pump bushing. Flush the cooler, refill with the fluid specified on your pan label or in the owner's manual, and run an adaptive relearn afterward.

Loaded. It is a complete original BMW 5HP19 forward clutch drum with its clutch pack, as shown in the photo.
Not guaranteed. This is the BMW version; the Audi, VW and Porsche FL and FLA units differ. Compare to your old drum or send your VIN.
Probably not. That pattern is documented on the F clutch drum, a different part. This drum is for slipping or late engagement in Drive.
ZF lists a test value of 3.09 to 4.58 mm for clutch A, measured and set with the snap ring.
Yes. Clear adaptations and drive a relearn cycle so the control unit relearns clutch fill times.
