5HP24 Planetary 1998-2004, used and ready to install. Fits the 5HP24. Ships fast from the USA.
If your Audi A6 4.2 or other ZF 5HP24-equipped car has developed a gear whine that climbs with road speed, or you opened the pan and found glitter on the magnet, the output planetary is one of the parts you end up looking for. This is a used, inspected output planetary gear for the 5HP24, removed from a 2002 Audi A6 sedan with the 4.2 liter V8. That car carries the 5HP24A, the all-wheel-drive version of the transmission used behind quattro drivetrains.
The 5HP24 is one of ZF's Simpson-type five-speeds. Instead of one compound gearset, it splits the work between separate planetary sets, and clutches D, E and F plus brakes A, B and C decide which member of each set is driven or held. The output planetary is the set tied to the output shaft at the rear of the gear train, so every forward gear and reverse passes torque through its pinions, its pinion shafts and its splines. When the pinion needle bearings wear, the pinions start to rock on their shafts, the gear mesh gets noisy, and the debris that comes off them travels through the rest of the transmission.
Not every 5HP24 noise is gears. Transmission Digest documented a squeal on lift-off in the 5HP19 and 5HP24 that sounded like a failing pump and was eventually traced to the stator sprag inside the torque converter, not the gear train. So note when the noise happens: on lift-off only, or under drive load in specific gears. Pull a fluid sample, look at the magnet, and check that your shifts are clean before condemning the planetary; a slipping clutch pack makes its own debris and is covered in our slipping diagnosis guide. If the unit is already out and the pinions are rough or pitted, replace the carrier rather than reusing it.
This gear came out of a 5HP24A in a 2002 A6 4.2, and the listing covers 1998-2004 A6 4.2 transmissions. The same transmission family was used in Audi A8 and S8, BMW V8 models, Jaguar V8 cars and the Range Rover, but the rear-drive and all-wheel-drive versions are built differently, and we have not confirmed that this output gear interchanges into the rear-drive BMW, Jaguar or Land Rover units. Read the ZF tag on your case (our ZF tag guide explains how the 1058 numbers break down), compare your old gear's tooth count, splines and photos side by side, or send us your year and VIN before ordering.

It was removed from a 5HP24A in a 2002 Audi A6 4.2. The rear-drive BMW and Jaguar 5HP24 units are a different version, and we have not confirmed this gear interchanges into them. Compare tooth count and splines with your old part or send us your year and VIN first.
The listing covers 1998-2004 Audi A6 4.2 applications of the 5HP24. The donor car was a 2002 A6 sedan with the 4.2 V8.
Used. It is an original-equipment gearset removed from a running transmission, cleaned and checked before it is listed.
Often not. A lift-off squeal in the 5HP19 and 5HP24 has been traced to the stator sprag in the torque converter. A planetary whine usually follows road speed under load and shows up with metal on the pan magnet.
The thrust washers and thrust bearings around the gearset, the filter, and all seals and gaskets from an overhaul kit. Flush the cooler and lines so old debris does not come back in.
