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 3-letter transmission code on the build sticker or stamped on the left side of the transmission case (must match HPH or verified compatible).
- Confirm engine is the 4.2L V8 FSI (engine code BAR).
- Inspect the vehicle's transmission wiring harness connector and TCM under the passenger seat for fluid contamination.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Heavy-duty transmission jack (250+ lbs)
- Engine support bar or subframe support rig
- Triple-square (XZN) sockets
- VCDS (VAG-COM) or equivalent professional scan tool
- Fluid pump and filler adapter (VAS 6262 or equivalent)
Budget for these consumables at install:
- ATF meeting VW G 055 025 A2 (or Aisin Type T-IV / JWS 3309 / Mobil 3309)
- Transmission filter (strainer) and oil pan gasket kit
- Torque converter seal (front pump seal)
- Transmission cooler-line flush solvent
What your vehicle’s computers will need after the swap:
What’s involved: Component Protection Removal & TCM Adaptive Relearn
sources differ: Arm 1 states no VIN-specific programming or immobilizer marriage is required, only a TCM Adaptive Relearn and Kick-Down Basic Settings via VCDS. Arm 2 states Component Protection Removal is required using a dealer-level tool (like ODIS) if the replacement valve body is used, alongside the TCM Adaptive Relearn. Cautious value 'yes' selected.
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 into the front pump before bolting to the engine to avoid cracking the pump.
- Fluid Fill Procedure: No dipstick is present. Must be filled from the bottom of the pan with the engine running, and fluid level finalized strictly between 35°C and 45°C.
- Wiring Harness Inspection: Check for oil in the 14-pin connector to prevent fluid wicking to the TCM.
- Transfer Case Alignment: Ensure proper alignment and lubrication of splines when bolting the transfer case to the rear of the transmission.
Easy to get right once you know them:
- Using the wrong ATF (generic synthetic instead of VW G 055 025 A2 spec)
- Checking fluid level with the engine off (causes severe underfilling)
- Failing to clear TCM adaptations and perform the relearn drive cycle
- Forgetting the filter O-ring or double-gasketing it
- Believing in 'lifetime' fluid and not performing a full flush at install
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 valve body or solenoids. Symptoms include harsh shifting, delayed gear engagement, gear flares, and severe thumps/bangs during downshifts.
🔎 Recommended at install: Replace internal wiring harness (solenoid loom) if oil is present in the connector to prevent fluid from wicking into the TCM.
🔎 Recommended at install: Replace front pump/torque converter seal during installation. Shudder can be addressed with fluid exchange or torque converter replacement.
🔎 Recommended at install: Address transmission fluid leaking from cooler lines near the oil temperature regulator caused by manufacturing burrs.

- 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

Returns (30 Days)
We accept returns of uninstalled parts within 30 days of delivery for this part.

- 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.
