8-Speed Automatic Transmission Assembly for 2012-2015 Audi A6, A7, A7 Quattro

A quick look at your own vehicle makes sure the right transmission shows up:

• Confirm the 3-letter transmission code is either NEU or NXT on the build identification sticker.
• Confirm the vehicle is equipped with Quattro All-Wheel Drive (AWD).
• Confirm the vehicle has the 3.0L Supercharged V6 gasoline engine.

What the install really takes — plan and budget with confidence:

Special tools this job needs:

• Triple Square (XZN) socket set
• Torx bit set
• Transmission jack
• Fluid transfer pump
• Advanced diagnostic scan tool (Audi ODIS, VCDS, or OBDeleven)
• Engine support brace
• Specialty tool T50069 (or equivalent) for torque converter bolts

Budget for these consumables at install:

• Transmission Fluid (ATF): ZF Lifeguard Fluid 8 or Audi factory spec G 060 162 A2 (approx. 7 to 10 Liters/Quarts for full fill)
• Filter & Pan Gasket Kit (Audi OEM part number 0BK398009A, includes new single-use aluminum pan bolts)
• Torque Converter Seal (OEM part number 0BK-498-111-B or equivalent)
• Axle output shaft seals
• Dedicated aerosol transmission cooler-line flush
• Quattro Differential Fluids (SAE 75W-90 synthetic, Audi spec G 055 145 A2) for front and center differentials

What your vehicle’s computers will need after the swap:

What’s involved: Security/Immobilizer Re-marriage (Audi Component Protection) and TCM Adaptive Relearn

The transmission features an internal mechatronics unit containing the TCM. Audi's Component Protection system will detect a VIN mismatch and lock the transmission (fault code P1701). Removal of Component Protection must be performed online by an authorized Audi dealer or independent specialist with an active Audi ODIS GeKo account.

Pro tips for a smooth first start-up — hand them to whoever does the install:

• Torque Converter Seating: Ensure the torque converter is fully seated (feeling three distinct clunks) before bolting to the engine to avoid crushing the internal oil pump.
• Temperature-Dependent Fluid Leveling: Fluid level must be checked with the vehicle perfectly level, engine running, and fluid temperature strictly between 35°C and 45°C (or 30°C and 40°C depending on spec) using a diagnostic tool.
• Quattro Differential Fluids: The unit contains three separate fluid chambers (ATF, front differential, and center differential) which must be checked and filled separately.
• Accessing Torque Converter Bolts: May require removing the starter motor to access bolts through the bellhousing. Use a high-quality six-point socket and break loose by hand.
• Subframe and Mounts: Requires removing the entire subframe and transmission mount crossmember. Pay attention to alignment marks and use new stretch bolts where specified.

Easy to get right once you know them:

• Assuming 'Plug-and-Play' Swap: Expecting the car to drive immediately without removing the Component Protection lock via ODIS.
• Reusing Aluminum Pan Bolts: Reusing the old stretch-to-yield bolts can cause them to snap or back out, leading to catastrophic fluid leaks.
• Using Generic ATF: Using cheap, generic multi-vehicle ATF causes immediate transmission shuddering, harsh shifting, and clutch slippage.
• Skipping the Cooler Flush: Debris from the previous failed transmission will circulate into the replacement unit and cause immediate damage.
• Misdiagnosing the Original Problem: Replacing the entire transmission when the issue is actually a faulty sensor, software problem, or solenoid.

Not issues with the units on this page — the manufacturer documented these for every transmission of this family, wherever you buy one. Handy for your installer:
