Filter and pan gasket service kit for the Aisin TR-60SN (VW code 09D) automatic, fitting Audi Q7, RS6 and VW Touareg from 2003 to 2010.
Owners of a VW Touareg or Audi Q7 with the six-speed automatic usually land here after a harsh 2-3 shift, a delayed engagement into Drive, or a shop quote for a fluid service that seems high for what it is. This kit covers the two parts that come off every time the pan is dropped on the Aisin TR-60SN, which VW and Audi code as the 09D: the internal strainer and the pan gasket. It replaces filter numbers 09D-325-435 and the earlier 09D-325-429.
The 09D is the rear-drive member of Aisin's six-speed family and the big brother of the front-drive 09G. Every clutch is applied by its own linear solenoid, and the valve body regulates those pressures very precisely. The strainer sits under the valve body and feeds the pump, so everything the solenoids see passes through it first. As friction material and varnish build up, the strainer restricts flow and the pump has to work harder to hold line pressure. On a transmission that shifts by modulating pressure this closely, a restricted feed shows up as shift quality problems well before anything is broken.
Be realistic about what a filter change can fix. Sonnax documents that the 09D's valve body wears at the solenoid modulator, clutch control, pressure regulator and lockup bores, and that wear causes harsh downshifts, lost fifth or sixth gear when hot and torque converter clutch complaints. New fluid and a clean strainer will not cure bore wear or a sticking solenoid. Our Aisin harsh and delayed shift guide walks through separating a fluid problem from a valve body problem.
Pull the codes, look at the fluid and look in the pan. Dark, burnt-smelling fluid with fine paste on the magnet is normal wear that a service addresses. Chunks of metal or clutch material point to internal damage, and a service will not help. If the shifts are only bad when hot, read Aisin slipping under load before you spend money, because that pattern often leads back to the valve body. If that is where you end up, we carry the 09D valve body and 09D solenoid kit.
The listing covers the Audi Q7 3.0L, 3.6L and 4.2L from 2007 to 2010 and the VW Touareg 3.2L and 3.6L V6, 4.2L V8 and V10 TDI from roughly 2003 to 2010. Audi's own parts catalog confirms the 09D-325-435 strainer, which replaced 09D-325-429, on the 2007 to 2010 Q7 with the 3.0L diesel and 4.2L gas engines. The listing also names the RS6 4.2L of 2003 and 2004; that car was built with a different automatic in some markets, so check the code on your transmission tag before ordering. The rule for every vehicle here is simple: if the transmission is a 09D / TR-60SN, the parts match. If you are unsure, send us the year and VIN.

It fits vehicles with the 09D / Aisin TR-60SN six-speed. That covers the 2007-2010 Q7 and the roughly 2003-2010 Touareg in the engines listed. Check the code on your transmission tag or send us the year and VIN if you are unsure.
No. The 09G is the smaller front-drive version of this transmission, and 09D and 09G parts mostly do not interchange. Order the kit that matches your transmission code.
It fixes shifting problems caused by old fluid and a restricted strainer. It does not fix valve body bore wear or sticking solenoids, which are common on these units. If the problem is worst when hot, plan to inspect the valve body.
The level is set through the fill plug, with the engine running and the fluid at the temperature specified in the factory procedure. You need a scan tool to read fluid temperature. Fill until fluid runs from the check hole at that temperature.
No. The gasket goes on dry against clean, flat surfaces. Remove all of the old gasket before you install the new one.
