09D Valve Body 2002-2016, remanufactured and ready to install. Fits the 09D. Ships fast from the USA.
A 09D that shifts fine on a cold morning but turns harsh, flares or loses its top gears after twenty minutes on the highway is one of the most searched complaints for the Touareg, Cayenne and Q7. This 09D valve body is listed for the 2002-2016 range, the broadest year window in our 09D lineup, and it is remanufactured so the worn control bores behind that hot-only behavior are replaced as a complete assembly.
Aisin's TR-60SN, coded 09D by Volkswagen, was introduced in 2002 as a longitudinal six-speed for luxury SUVs. There is no traditional shift valve train doing the work: each clutch has a dedicated linear solenoid that controls how fast it fills and exhausts, and the control module overlaps two or three clutch elements on every shift. All of those solenoids are fed regulated oil by the solenoid modulator valve. When that valve or a clutch control valve wears its bore, the module can no longer time the overlap correctly, and the result is a harsh or flared shift even though the clutches themselves may be in decent shape. That is why a valve body often fixes a 09D that a shop has already called worn out.
Because temperature is the trigger on so many 09D complaints, test it hot. Drive until the fluid is fully up to operating temperature, then watch transmission temperature and gear data on a scan tool while you reproduce the problem; our live data guide explains what to look at. Sonnax notes that solenoid plungers commonly seize in their coil bushings once warm, and that can be checked on the bench with a hot soak test, so a single sticking solenoid is not mistaken for bore wear. Then check the fluid against our ATF color and smell chart. If it is very dark and burnt, the clutches have taken damage and the unit needs internal repair, not only a valve body.
This listing covers 09D/TR-60SN applications from 2002 through 2016. In practice the 09D is best known in the first-generation Touareg, the early Cayenne and the first Q7, and the later redesigned versions of those SUVs moved to eight-speed automatics, so a late-model vehicle may not have a 09D at all. Do not order by model year alone. Read the transmission code on the case tag, or send us your year and VIN and we will confirm. This unit will not fit a front-drive 09G. If your vehicle sits squarely in the earlier years, you can also compare the 2002-2011 09D valve body, and our Aisin transmission parts page lists everything else for this family.
Treat the valve body as part of a service, not a bolt-on. Drop the pan, clean the magnet and pan, and fit a new filter and gasket from our TR-60SN filter and pan gasket kit so old debris does not reach the new bores. Check the large solenoid connector and the internal harness for heat-cracked insulation before you reinstall. Torque the bolts in the factory sequence, refill with the VW/Audi-approved ATF and check the level hot at the fill plug. Clear codes, reset the adaptations with a VAG-capable tool and complete a relearn drive. If the unit has high mileage and you are already in the pan, our 09D shift kit is worth reviewing.

Only if that vehicle actually has a 09D. Later redesigned Touareg, Cayenne and Q7 models moved to eight-speed automatics, so check the transmission code on the case tag or send us your VIN before ordering.
Worn solenoid modulator and clutch control bores and sticking solenoid plungers usually show up only at operating temperature, so a cold test can make a bad valve body look healthy.
Often, if the fluid is clean. Valve body and solenoid wear cause harsh and flared shifts with minimal clutch damage. Very dark, burnt fluid with clutch material means internal repair is needed too.
Use the VW/Audi-approved ATF specified for your 09D and set the level hot through the fill plug. Do not use a generic multi-vehicle fluid.
Yes. Reset the shift adaptations with a VAG-capable scan tool and complete a relearn drive so the module retimes clutch overlap for the new valve body.
