Know This Transmission Before You Buy
The research behind our purchase interview — recalls, bulletins and real install economics for this transmission family:
A quick look at your own vehicle makes sure the right transmission shows up:
- Verify the three-letter transmission code on the vehicle identification sticker or the physical ID plate is NNT or QCZ.
- Confirm the vehicle has the 3.0L V6 Supercharged Gasoline engine.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Triple Square (XZN) socket set (M10, M12, M14)
- Torx socket set (T30, T40)
- Engine support bar
- VCDS (Vag-Com Diagnostic System) or ODIS scan tool
- Fluid pump adapter (VAS 6262/2 or equivalent)
Budget for these consumables at install:
- ZF Lifeguard Fluid 8 (Audi spec G 060 162 A2)
- Replacement transmission oil pan assembly (with integrated filter and gasket)
- New single-use aluminum pan bolts
- Torque converter / input shaft seal
- Transmission cooler line flush solvent
- Front differential fluid (SAE 75W-90 synthetic)
- Center differential fluid (Audi spec G 055 145 A2)
What your vehicle’s computers will need after the swap:
What’s involved: Component Protection (anti-theft/immobilizer re-marriage) and TCM Adaptive Relearn
This transmission features Audi's Component Protection system. Upon installation, the TCM will detect a VIN mismatch and lock the transmission into a restricted safe mode (preventing shifting out of Park or 1st gear). This must be cleared online by an authorized Audi dealership or specialist using ODIS with GEKO access.
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 (three distinct clicks/drops) before bolting the transmission to the engine to avoid cracking the internal oil pump.
- Fluid Fill Procedure: Must be performed with the vehicle level, engine idling, and fluid temperature strictly between 30°C and 40°C (or up to 50°C) monitored via diagnostic software.
- ABS Sensor Dependency: A faulty Right Front ABS/wheel speed sensor can cause erratic shifting or prevent adaptation without throwing an ABS light.
- Single-Use Bolts: Subframe, transmission mount, and bellhousing aluminum stretch bolts must be replaced.
- Torque Converter Bolt Access: Access to the torque converter bolts often requires removing the starter motor.
Easy to get right once you know them:
- Reusing the old transmission pan/filter, which starves the pump and contaminates the replacement unit.
- Using generic multi-vehicle ATF instead of genuine ZF Lifeguard 8 or Audi G 060 162 A2.
- Assuming the transmission is defective when it locks in Park, failing to realize Component Protection must be removed via ODIS.
- Ordering a ZF 8HP55 from an incompatible model (like an A8 or Q5) with mismatched final drive ratios.
- Skipping the transmission cooler and line flush, introducing old debris into the replacement unit.

Policies, in plain English.
Shipping & Handling
- Ships by LTL freight on a pallet — a real freight truck, not a parcel van
- Your checkout freight quote covers delivery to your door (liftgate service included for residential addresses)
- The carrier calls ahead to schedule a delivery window — someone must be present to receive it
- Typically palletized and picked up within 2–3 business days; transit time depends on distance
120-Day Warranty
This part includes a 120-day warranty.
- If the part fails within the warranty window, we'll replace it or refund per the coverage terms
- Coverage is parts-only — installation labor is not included
- Warranty covers defects — not installation errors, misuse, or damage after installation
Your pre-purchase interview reviews these exact terms with you before anything is charged.
Returns (30 Days)
We accept returns of uninstalled parts within 30 days of delivery for this part.
- Defective parts: We will replace the part or issue a refund at our discretion
- Programming: "Needs to be programmed to my vehicle" is not a valid return reason. Many modules require dealer programming — we're happy to help connect you with resources if your dealer says it's not programmable
- Return shipping: This part ships by freight (LTL) — the part price is refundable per the terms above, but shipping costs are non-refundable and return freight follows the seller's return terms. Your pre-purchase interview walks through the exact numbers before you buy
- Parts must be returned in original packaging and unmodified condition
- Poorly packaged returns that arrive damaged will not be credited
Damaged in Shipping?
Freight damage is rare — and you're fully protected when you do two things at delivery:
- Inspect before you sign — you're allowed time to look the pallet over while the driver waits
- Write any damage on the delivery receipt before signing — that one line is what makes a freight claim succeed
- Severe damage? Refuse the delivery — it goes back at no cost to you and we make it right
- Photograph the pallet before unwrapping; report concealed damage within 24 hours of delivery
We handle the carrier claim — you just help document it. Your pre-purchase interview walks through this checklist too.
Order Cancellation
Cancel before shipment for a full refund. Once the pallet has been built, a preparation charge may apply — and once the freight carrier picks it up, shipping costs are non-refundable and standard return terms apply. Your pre-purchase interview shows the exact numbers before you pay.
