ZF 6HP19 Transmission Master Rebuild Kit w/ Filter BMW

Everything you need to tear down and reseal a ZF 6HP19 six-speed automatic in one box. This is the transmission behind the 2004-2015 rear-drive BMW lineup, so it covers the 128i, 135i, 325i, 328i, 330i, 335i, 525i, 528i, 530i, 535i, 740i, 750i, M3, X1 xDrive35i, X5 and Z4. It replaces ZF service numbers 6HP19 and T14300A (made up of T14302A, T143080A and T143081A). Match your original part numbers before ordering, since ZF ran several variants of this unit.

Inside the kit you get the full friction clutch pack, the matching steel plate set, a complete overhaul gasket and seal kit, and the internal pan filter. That is the parts list for a bench rebuild: pull the unit, strip the clutch drums, and reassemble with fresh frictions, new steels, new sealing rings and a clean filter so the box holds line pressure again.

These transmissions come in for harsh or delayed shifts, slipping under load, and slow engagement once the clutch material wears and the seals harden. A master kit like this restores the clutch clearances and sealing surfaces so shift quality and holding capacity come back. Plan on a full ATF refill and, on the mechatronic-equipped units, a fresh sleeve and adapter seal at the same time.
