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 5th digit of your VIN is Y (which designates the 3.6L BHK engine).
- Locate the 3-letter transmission code on your vehicle's data sticker (found in the spare tire well or in the original service booklet) and verify it matches LLK.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support bar / bridge (10-222 A)
- Heavy-duty transmission jack (V.A.G 1383A)
- Triple-square (XZN) and Torx sockets
- Fluid fill pump adapter (specifically for the ZF fill plug / T40058)
- VCDS or ODIS diagnostic scan tool
Budget for these consumables at install:
- Automatic Transmission Fluid (sources differ: Audi G 055 162 A2 / ZF LifeguardFluid 6 vs VW/Audi G 055 025 A2 — confirm with us before install)
- Transmission Filter & Pan Gasket Kit
- Torque Converter Seal (Front Pump Seal)
- Axle / Output Shaft Seals
- Transmission Cooler Flush
What your vehicle’s computers will need after the swap:
What’s involved: Security/immobilizer re-marriage (Component Protection removal) and TCM adaptive relearn
sources differ on TCM location and programming: TCM is integrated inside the transmission case and locked by Audi's Component Protection system vs TCM is a separate unit located under the front passenger seat requiring adaptive values reset and basic settings. Both sources agree that dealer-level tools (ODIS) or advanced independent tools (VCDS) are required to perform the adaptation/re-marriage procedure correctly.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque Converter Seating: Ensure the torque converter is fully and correctly seated into the transmission's front pump before bolting the transmission to the engine. If it is not fully seated, tightening the bellhousing bolts will crack the transmission case or destroy the front pump.
- Fluid Level Check Procedure: The fluid level must be checked via a fill plug on the bottom of the pan. The procedure is highly temperature-dependent. The vehicle must be perfectly level, running, and the transmission fluid must be within a specific temperature range (35°C to 45°C), monitored with a diagnostic scanner.
- Component Protection / Immobilizer: The used transmission may trigger Component Protection as soon as the key is turned, requiring ODIS online access to clear, or swapping your original mechatronic unit into the replacement transmission.
- Cooler Line Flush: You must thoroughly flush the transmission cooler lines to clear out any debris from the old, failed unit before connecting them to the replacement transmission.
Easy to get right once you know them:
- Ordering for the wrong engine/year: The LLK transmission is specific to the 3.6L V6 engine. The 4.2L V8 and 3.0L TDI models use different transmissions and are not interchangeable.
- Ignoring Component Protection: Assuming the transmission is defective because the car won't move or shifts erratically, not realizing that the transmission is locked by the vehicle's immobilizer system and requires programming.
- Reusing the old Mechatronic Sealing Sleeve/Bridge Seal: Reusing these cheap rubber seals often leads to immediate leaks or pressure loss shortly after installation.
- Improper Fluid Leveling: Not following the strict temperature-based fill procedure or using the wrong type of ATF.
- Skipping the Cooler Flush: Failing to properly flush the transmission cooler and lines, which circulates debris from the previously failed transmission directly 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.
