Full overhaul kit for the Aisin 09K TF-61SN six-speed in 2003-2015 VW Transporter T5: frictions, steels, pistons, seals and gaskets.
The 09K is Volkswagen's code for the Aisin TF-61SN, the six-speed automatic fitted to the higher-output T5 Transporter, Multivan and Caravelle vans. These vans spend their lives loaded, towing or idling in traffic, and the usual story is a flare on the 2-3 upshift, a shudder when the converter locks up on a grade, or slipping once the unit is hot. When the fluid comes out dark with friction material in it, the clutch packs are finished and the unit needs a teardown. This master overhaul kit carries the soft parts for that job, including the bonded pistons that harden and start to bypass on high-mileage units.
The TF-61SN is a transverse front-drive six-speed, also catalogued as the AQ400, built to handle up to 400 Nm. Its ratios run from a 3.949 first gear to a 0.688 sixth on the 3.2L van, and every shift is a hand-off between hydraulically applied clutches and brakes controlled by the valve body solenoids. Each pack depends on good friction material and on pistons that seal. This kit replaces friction plates, steel plates, bonded pistons, seals, O-rings and gaskets in one box, so every apply circuit is renewed at the same time instead of fixing the one pack that failed and waiting for the next.
Not every shift complaint on a 09K is a clutch failure. Clogged valve body passages from overdue fluid changes, a worn lockup clutch inside the converter and pump bushing wear from vibration can all cause similar complaints. Check the fluid level hot at the check plug, read stored codes, and pull the pan to see what is on the magnet. Our guide on shift flare versus slip explains how to tell a pressure or timing problem from worn frictions, and Aisin slipping under load covers the pressure checks to run first.
This kit is listed for 2003-2015 VW Transporter T5 and T5.1, Multivan and Caravelle with the 09K / TF-61SN, and it cross-references 09K321011H, 09K321015D, 09K321021R and 09K321025F. Reference data dates TF-61SN production to 2003-2009, with the 2.5L five-cylinder TDI and 3.2L V6 as the main applications, so on a later van read the code on the transmission tag before ordering; some parts catalogs also mix up the 09K with the TF-62SN. If you are unsure, send us the year, engine and VIN. The 09K has no dedicated collection page yet; related units are grouped under Aisin transmission parts.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2003-2015 VW Transporter T5 and T5.1, Multivan and Caravelle with the 09K / TF-61SN six-speed automatic, cross-referenced to 09K321011H, 09K321015D, 09K321021R and 09K321025F. Check the code on the transmission tag before ordering, since later vans and some catalogs use other Aisin units.
No. The kit includes friction plates, steel plates, bonded pistons, seals, O-rings and gaskets. The filter, pan gasket, torque converter and hard parts are separate.
VW specifies its own ATF for the 09K, part G 052 025 A2. Total capacity is about 7.0 L, and the level must be set with the unit at operating temperature through the check plug, not by quart count.
The cooler on these vans is easy to restrict, and heavy loads or towing raise fluid temperature fast. Reference data on the TF-61SN ties early failures to a dirty heat exchanger, so flush or replace the cooler during the rebuild.
Only if the fluid is clean and the problem is electrical or valve body related. Once the pan shows friction debris and the unit slips under load, the clutch packs are worn and a full rebuild with this kit is the fix.
