PORSCHE 911 996 Gearbox 3.6 2s A9610 Tiptronic

For the Porsche 911 (996) Carrera 2, the A96.10 is the specific 5-speed Tiptronic S automatic transmission paired with the 3.6L flat-six engine (996.2 Facelift, 2002–2005).

While the early 3.4L 996s used a ZF-sourced transmission, the A96.10 is a Mercedes-Benz (722.6 / 5G-Tronic) based unit. This was a significant upgrade in durability and torque capacity for the 320 hp M96.03 engine.

1. Technical Specifications (A96.10)

The Mercedes-sourced 5G-Tronic is widely considered one of the most robust automatic transmissions of its era, often found in high-torque V12 and AMG models.

• Transmission Type: 5-Speed Tiptronic S (Automatic with manual shift mode).

  Manufacturer Code: Mercedes 722.270.050.0 (also labeled as Porsche A96.10).

• Gear Ratios:

  • 1st: $3.59$ | 2nd: $2.19$ | 3rd: $1.41$ | 4th: $1.00$ | 5th: $0.83$

  • Reverse: $3.16$

• Drive System: Rear-Wheel Drive (2S / Carrera 2).

• Weight: ~115 kg (255 lbs) with the torque converter and fluids.

2. Common Part Numbers

If sourcing a replacement for a 2002–2005 3.6L Carrera, look for:

• Porsche OEM: 996.300.010.51 (or suffixes .53, .55).

• Identification: The gearbox casing will typically be stamped with A9610.

3. 2026 Market Value

In 2026, as the 996 moves firmly into “classic” status, these transmissions are valued for their reliability compared to the manual G96 units, which are often prone to synchro wear.

4. Maintenance & Fluid Service

The A96.10 is “old school”—it likes fresh oil. Despite Porsche’s original “Lifetime” claim, 2026 specialists recommend service every 60,000 miles.

• Fluid Type: ATF 134 (Mercedes-Benz Sheet 236.14).

• Filter/Gasket Kit: Readily available and inexpensive due to the Mercedes cross-compatibility.

• The “Conductor Plate”: A common failure point in the 722.6 architecture. If the car gets stuck in “Limp Mode” (2nd gear only), you likely only need to replace the internal plastic conductor plate (approx. $150 parts) rather than the whole gearbox.
