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 transmission code on the vehicle data sticker (spare tire well or maintenance booklet) is PRU.
- Verify the physical tag on the underside of the transmission case displays '8HP-55' and 'PRU'.
- Confirm the vehicle is an AWD (quattro) model with a 2.0L Turbo engine.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Heavy-duty transmission jack
- Engine support bar/bridge
- Triple Square (XZN) and Torx bit sockets
- Audi-specific fluid filling adapter and pump
- Diagnostic scan tool capable of reading real-time fluid temperature (VCDS or ODIS)
- Diagnostic tool with online GeKo access (ODIS) for anti-theft unlock
Budget for these consumables at install:
- Transmission Fluid: OE-spec fluid meeting Audi G 060 162 A2 specifications (such as ZF Lifeguard 8 or Liqui Moly Top Tec 1800)
- Transmission Filter & Pan Gasket Kit (filter is integrated into the plastic oil pan)
- Torque Converter Seal (input shaft seal)
- Axle output seals
- Aluminum stretch bolts for the transmission crossmember, driveshaft, and mounts
- Professional transmission cooler line flush
What your vehicle’s computers will need after the swap:
What’s involved: Component Protection (Immobilizer) Unlock & TCM Adaptive Relearn
This transmission is equipped with Audi's Component Protection (CP) anti-theft system. Upon installation, the TCM will lock into safe mode (preventing movement) until unlocked online by an Audi dealer or specialist using ODIS with a licensed GeKo connection. A basic settings and adaptation relearn must also be performed.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque Converter Seating: The converter must click into place multiple times and sit fully recessed. Bolting the transmission to the engine without full seating will crush the internal oil pump, destroying the unit.
- Fluid Fill Temperature Window: Final fluid level check must be performed with the engine running, vehicle level, and fluid temperature strictly between 30°C and 50°C (or 35-45°C depending on spec) monitored via scan tool.
- Crossmember Removal: The transmission crossmember must be completely removed to access the pan or upper bellhousing bolts; the transmission must be safely supported.
- Solenoid / Valve Body Swapping Pitfall: Do not swap your old mechatronic unit to bypass programming. Audi made mid-generation hardware changes (e.g., solenoid count differences), and mismatched valve bodies cause severe shifting issues and fault codes.
Easy to get right once you know them:
- Assuming the transmission is defective because it won't move after installation, unaware that Audi's Component Protection system has locked the unit.
- Swapping the old TCM/valve body to avoid dealer programming fees, which often leads to hardware mismatches and ruined clutch packs.
- Reusing old fluid or using cheap, non-spec generic multi-vehicle ATF.
- Failing to professionally flush the cooler lines, which pumps trapped debris from the failed unit directly into the replacement transmission.
- Ignoring the adaptation relearn process after Component Protection is removed.
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: Replace torque converter; flush system to remove friction material debris that clogs solenoids.
🔎 Recommended at install: Replace pressure control solenoids or the entire mechatronics unit. Symptoms include harsh/delayed shifts, jerking, or limp-home mode.
🔎 Recommended at install: Replace the plastic electrical connector sleeve and O-rings.
🔎 Recommended at install: Check for torque converter lock-up clutch issues or fluid degradation.

- 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

- 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.
