09D Clutch Drum, used and ready to install. Fits the 09D. Ships fast from the USA.
A Touareg, Cayenne or Q7 with the 09D six-speed that is slow to pick up reverse, flares on the 2-3 shift, or slips going into 5th is often losing pressure in the K3 clutch. This listing is a used K3 clutch drum for the 09D (Aisin TR-60SN), the 5-clutch version from the 2002-up design, catalogued as interchange 235555A. Its identifying measurement is 1.555 inches from the top of the drum to the snap ring, which is the quickest way to match it to your old part.
Transmission Digest describes the 09D as the rear-drive version of the 09G with the same clutch elements, and the Aisin application chart for that family shows K3 applied in reverse, 3rd and 5th. That makes K3 the busiest clutch for shift quality: it comes on for the 2-3 and 4-5 upshifts and for reverse engagement, and it releases on the 3-4 and 5-6. The drum carries the K3 steels and frictions, the apply piston and its return spring, and it rides on sealing rings that feed it oil. A linear solenoid pulses K3 on and off, so a leak anywhere in the drum shows up as a soft or late engagement that the computer then tries to correct.
Valve body wear can mimic all of this. Sonnax notes that worn clutch control valve bores on the 09D cause flare upshifts and harsh downshifts, and worn pressure regulator bores cause line rise and converter clutch complaints.
Because the 09D has a pressure tap for each clutch, you can watch K3 directly. Check K3 pressure in reverse and in 3rd. If line pressure is good but K3 pressure drops or builds slowly, the leak is in the drum, its seals or the sealing rings. If K3 pressure is fine and it still slips, the pack itself is worn. Our pressure testing guide covers the gauge work, and Aisin slipping under load explains how to separate a mechanical slip from a hydraulic one. A scan tool helps too: our live data guide shows how to log commanded gear against actual ratio.
This drum fits the 09D/TR-60SN from 2002 on, as used in the VW Touareg and Porsche Cayenne in North America and in the Audi Q7; the interchange also lists some overseas Toyota models with the same Aisin unit. Do not order on the vehicle alone. Measure your old drum from the top edge to the snap ring and compare it with 1.555 inches, confirm the 5-clutch count, and compare the photos. If anything does not line up, send us the year, make, model and engine before ordering. Browse the rest of the range on our Aisin transmission page.

This is the K3 drum for the 5-clutch pack. Measure your old drum from the top edge to the snap ring; this one is 1.555 inches. Then compare the clutch count and the photos.
In this Aisin six-speed family K3 is applied in reverse, 3rd and 5th. A slipping K3 usually shows up as late reverse, a 2-3 flare or a 4-5 flare.
No. The K2 drum has the shaft attached and handles 4th through 6th. If you need that one, it is listed as our 09D K2 clutch drum with shaft for 2002-up.
New K3 frictions and steels, piston seals and the sealing rings that feed the drum, plus a filter and pan gasket. Clear the adaptations after the rebuild.
Use the transmission fluid VW, Audi or Porsche lists for your vehicle and check the level at operating temperature with the engine running, following the factory procedure.
