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 an AWD model (Carrera 4 or Carrera 4S) from model years 2002–2005.
- Verify the transmission data plate on the bottom of the case reads A96.35 (or Porsche part number 7222700600).
- Verify the vehicle has a front differential and front driveshafts.
- Confirm the vehicle has the Tiptronic automatic transmission, not a manual gearbox.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Porsche-specific scan tool (PIWIS, PST2, Durametric, or high-end Autel)
- Transmission fluid pump with hook adapter
- Torx and Hex bit sockets (T-45, 17mm hex)
- Engine/transmission support bar or specialized drop cart
- Infrared thermometer
Budget for these consumables at install:
- ATF meeting MB 236.10 or MB 236.14 specifications (e.g., Shell ATF 3403-M115, Pentosin ATF 1, Shell ATF 134, Fuchs Titan 4134, or Genuine Porsche ATF)
- Transmission filter and pan gasket kit
- Electrical connector guide bushing (pilot bushing) with fresh O-rings (Mercedes part # 2035400253 or Porsche equivalent)
- Torque converter seal (front pump/input shaft seal)
- Cooler-line flush solvent
- Front differential gear oil (SAE 75W-90 GL-5, approx 1.2 liters)
What your vehicle’s computers will need after the swap:
What’s involved: TCM Adaptive Relearn / Adaptation Reset
A dealer-level scan tool (PIWIS, PST2, Durametric, or equivalent bidirectional tool) is required to clear stored fault codes and reset the TCM adaptation values. Skipping this step will cause the TCM to apply hydraulic pressures learned from the old, worn transmission, resulting in harsh or erratic shifting.
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 onto the input shaft and oil pump gears (three distinct clicks/drops) before bolting to the engine. Failure to do so will crack the transmission oil pump gear upon tightening.
- Connector Plug Bushing Torque: The small 7mm bolt in the center of the plastic connector bushing requires only 2.5 Nm (22 in-lbs) of torque. Over-tightening will strip the brass nut embedded in the conductor plate, requiring pan removal and conductor plate replacement.
- Fluid Fill Temperature Procedure: The transmission has no dipstick. It must be filled from the bottom plug, and the final level check must be performed with the engine running, transmission in Park, and fluid temperature strictly between 30°C and 45°C (86°F to 113°F) monitored via scan tool. Incorrect temperature checks cause severe under- or over-filling.
- Engine/Transmission Drop: Standard procedure requires dropping the engine and transmission together as a single unit from the bottom of the vehicle, then separating them.
Easy to get right once you know them:
- Ordering for a RWD Carrera: This AWD transmission (A96.35) has an integrated transfer case and will not fit a RWD chassis (which requires A96.10).
- Ordering for an Early 996 (1999-2001): Early Carrera 4 models use a ZF 5HP19 (A96.30) which is completely incompatible with this Mercedes-sourced unit.
- Reusing the Leaking Connector Bushing: Skipping replacement of the cheap plastic connector bushing leads to fluid leaks and wicking that can destroy the cabin-mounted TCU.
- Improper Fluid Level Check: Checking fluid with the engine off or at incorrect temperatures leads to severe shifting issues, slipping, and limp mode.
- Using Generic ATF: Failing to use MB 236.10 or MB 236.14 spec fluid causes torque converter shudder and poor shift quality.
- Skipping the Adaptation Reset: Failing to clear TCM adaptations after installation causes harsh shifting, leading buyers to think the replacement unit is defective.
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 the internal plastic conductor plate (housing speed sensors N2 and N3) to resolve or prevent limp mode and diagnostic codes like P0715 or P0720.
🔎 Recommended at install: Replace the electrical connector guide bushing (pilot bushing/plug adapter) with new O-rings to prevent fluid from leaking and wicking up the wiring harness into the TCM.
🔎 Recommended at install: Flush fluid or replace torque converter if shudder/clunking occurs around 2,000–2,500 RPM in 2nd gear.

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.
