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:
- Confirm the vehicle is a Quattro (AWD) model.
- Verify the engine is a 2.0L Turbocharged 4-cylinder.
- Locate the vehicle identification option sticker in the trunk or owner's manual and confirm the transmission code is MXW.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Triple Square (XZN) spline bit socket set
- Torx and Hex bit sockets
- Transmission jack
- Engine support brace
- Fluid transfer pump with dedicated fill adapter
- Diagnostic scan tool (VCDS, ODIS, or equivalent)
Budget for these consumables at install:
- ZF LifeguardFluid 8 (Audi spec G 060 162 A2)
- New transmission oil pan gasket and integrated fluid filter kit
- New input shaft / torque converter hub seal
- Transmission cooler-line flush aerosol
- Two new O-rings for transmission cooler lines (Audi Part #N90666003)
- Replacement stretch bolts for the structural X-brace and transmission mount
What your vehicle’s computers will need after the swap:
What’s involved: Component Protection (Immobilizer) Unlock and TCM Adaptive Relearn
The integrated TCM is locked to the donor vehicle's VIN via Audi's Component Protection system. Upon installation, fault code P1701 will trigger, locking the transmission in Park or limp mode. Unlocking requires ODIS connected to an active online GeKo account. A TCM adaptive reset and drive cycle relearn must also be performed.
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 (clicking three times and sitting recessed) before bolting to the engine to avoid crushing the internal oil pump.
- Fluid Level Temperature Window: The final fluid level check must be performed only when the ATF temperature is strictly between 30°C and 45°C (86°F to 113°F) with the engine running.
- X-Brace and Mount Support: The structural aluminum X-brace and transmission mount crossmember must be supported securely before removal, and stretch bolts must be replaced.
- Accessing Torque Converter Bolts: Accessing these bolts may require removing the starter motor to work through its mounting hole.
Easy to get right once you know them:
- Ordering for a Front-Wheel-Drive (FWD) vehicle which uses a Multitronic CVT instead of this AWD unit.
- Reusing old transmission fluid or using cheap, non-spec generic ATF instead of ZF LifeguardFluid 8.
- Failing to flush the transmission cooler lines, which introduces debris from the failed unit into the replacement.
- Bypassing programming by swapping the mechatronics unit without using dedicated guiding pins, bending the park rod actuator.
- Misdiagnosing a fixable software or mechatronics issue as a complete transmission failure.
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:
🔎 Recommended at install: Diagnose selector shaft seal or wiring harness connector sleeve before replacing pan gasket.
🔎 Recommended at install: Update TCM software using Audi's Software Version Management (SVM action code 02A048).
🔎 Recommended at install: Replace the transmission fluid cooler adapter seals and ensure correct seating.
🔎 Recommended at install: Replace solenoids, repair internal hydraulic leaks, or replace/rebuild the electronic control unit.
🔎 Recommended at install: Replace the torque converter lock-up clutch or the entire torque converter assembly to prevent fluid contamination.

- 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

- 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

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

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.
