09D Valve Body 2002-2011, remanufactured and ready to install. Fits the 09D. Ships fast from the USA.
A VW Touareg, Porsche Cayenne, or Audi Q7 with the Aisin-built 09D (also called the TR-60SN) six-speed automatic that downshifts harshly, falls out of 5th or 6th once it’s warm, or flares on upshifts is almost always pointing at the valve body. This remanufactured 09D valve body covers 2002-2011 applications and replaces the hydraulic assembly as a complete unit instead of chasing individual bores.
The 09D/TR-60SN is the rear-wheel-drive version of VW/Audi’s front-drive 09G, strengthened by Aisin AW for the extra torque of a longitudinal V6/V8 layout. Each clutch element in this transmission is applied through a linear solenoid rather than a simple on/off circuit, and the valve body is where those solenoid signals turn into actual clutch and band pressure. The bores that house the solenoid modulator valve, the clutch control valves, and the primary/secondary pressure regulators are precision-fit aluminum, and they wear from years of debris and heat cycling.
Sonnax’s published technical notes on this platform trace most of these complaints to specific bore wear: solenoid modulator valve wear causes the harsh-downshift and hot-gear-loss symptoms, clutch control valve wear causes flare on upshift and harshness on downshift, and worn pressure regulator bores cause the line-rise and TCC complaints. Because the solenoids themselves can also stick from debris after the transmission reaches operating temperature, have a shop check solenoid resistance and run a pressure test before assuming the valve body alone is at fault - a tired solenoid can produce the same symptom as a worn bore. If the clutches are worn as well, our 09D Overhaul Kit covers the broader rebuild.
This valve body is listed for 2002-2011 09D/TR-60SN applications, which spans the VW Touareg, Porsche Cayenne, and Audi Q7 built on this Aisin platform. The Q7 moved to an 8-speed automatic around the 2011 model year, so if your Q7 is a late 2011 build, confirm your transmission code (09D/TR-60SN vs. the 8-speed) before ordering, or send us your VIN. The 09D does not interchange with the front-wheel-drive 09G, so match your part number rather than relying on the model year alone - our 09D Transmission Valve Body with Shift Solenoids listing is the version to compare against if yours came with solenoids already attached.
Drop the pan and filter first and replace both along with the pan gasket - see our 09D/TR-60SN Filter & Pan Gasket Kit - so debris from the old unit doesn’t contaminate the new valve body on day one. Mark each linear solenoid’s position before disconnecting it, since several look alike and a mismatched reinstall will reproduce a shift complaint. If the internal harness or a solenoid connector is damaged or corroded, pair this job with our 09D Internal Wiring Harness. Refill with the transmission’s specified fluid and, on this adaptive platform, have the shift adapts reset with a VAG-capable scan tool after the swap so the control module relearns line pressure from a clean baseline.

It's built for 2002-2011 applications of the Aisin 09D/TR-60SN six-speed, used in the VW Touareg, Porsche Cayenne, and Audi Q7. Because the Q7 switched to an 8-speed transmission around 2011, confirm your transmission code or VIN before ordering if your vehicle is a late 2011 build.
No. The 09D and 09G share a design lineage but their valve body parts do not interchange. This listing is for the rear-wheel-drive 09D/TR-60SN only - match your part number against your old unit before ordering.
Harsh downshifts that show up once the fluid is hot, losing 5th or 6th gear when warm, flared upshifts, and torque converter lockup surge or shudder are the typical signs of valve body bore wear on this transmission.
Install a new filter and pan gasket at the same time and refill with the correct fluid. If any solenoid or the internal harness tests out of spec, replace it rather than reusing a worn part - a bad solenoid can mimic the same symptoms as a worn valve body.
Yes. This platform is adaptive, so after the valve body swap have a VAG-capable scan tool reset the transmission control module's shift adapts. Expect firmer shifts for the first several miles while it relearns line pressure.
