FERRARI F430 SCUDERIA SPIDER 16M Gearbox 247320

the part number 247320 refers to the F1 SuperFast II Gearbox Assembly for the Ferrari F430 Scuderia and the Scuderia Spider 16M.

This is not a standard F430 gearbox. The 247320 unit is the pinnacle of Ferrari’s single-clutch automated manual technology, famous for its 60-millisecond shift times—the fastest ever achieved by Ferrari before they transitioned to dual-clutch systems.

1. Technical Identification

• Part Number: 247320 (Specific to Scuderia/16M models).

• Gearbox Type: 6-speed automated manual with the SuperFast II software and hardware package.

• Key Differences from Standard F430: * Revised internal gear ratios for better acceleration.

  • Upgraded synchromesh and shifting forks to handle the 60ms shift speed.

  • Integration with the E-Diff 2 electronic differential (housed within the same assembly).

  • Lightweight internal components to reduce rotational inertia.

2. 2026 Market Pricing (Estimated USD)

Due to the rarity of the 16M (only 499 units) and the Scuderia, this gearbox is extremely difficult to find “New” in 2026. Most transactions involve refurbished units or specialist repairs.

3. Common 2026 Maintenance & Issues

If you are searching for part 247320, you may be dealing with one of these “Scud-specific” issues:

• E-Diff Solenoid Failure: The electronic differential is integrated. If the internal solenoids fail, the car will throw an “E-Diff” error and may default to a “limp mode.”

• Shift Fork Wear: Because of the violent 60ms shifts, the internal mechanical forks and synchros can suffer more wear than a standard F430, especially if the car has been tracked extensively.

• Potentiometer Drift: The sensors (Selection and Engagement) can lose calibration over time. In 2026, it is highly recommended to replace these sensors whenever the gearbox is out of the car.

4. Installation & Programming

• SuperFast II Software: The 247320 unit must be paired with the correct TCU (Transmission Control Unit). A standard F430 TCU will not be able to command the 60ms shift times of this hardware.

• Clutch Kiss Point (PIS): Like all F1 gearboxes, the Scuderia requires a precise PIS calibration via the Ferrari DEIS/SD3 tool. For the 16M, this setting is critical; if it’s off by even 0.1mm, the car will “clunk” or slip.

• Oil Specs: Use only Shell Spirax S5 ATE (or the updated 2026 equivalent). The Scuderia gearbox runs hotter than the standard car, so fluid quality is paramount.
