Ferrari 488 GTB Complete Gearbox 807337
The Ferrari 488 GTB complete gearbox (807337) is the factory 7-speed dual-clutch transmission (DCT) used on the F142M platform. It is a rear-mounted transaxle unit combining the gearbox, hydraulic control system, and electronic differential integration.
OEM Part Overview
- Part number: 807337
- Type: 7-speed Dual-Clutch Transmission (DCT) complete assembly
- Application:
- Ferrari 488 GTB
- Ferrari 488 Spider
- Ferrari 488 Pista
- Ferrari F8 Tributo / Spider (shared architecture with updates)
- Layout: Rear transaxle with integrated differential system
This gearbox is the successor evolution of Ferrari’s earlier 458 DCT system, updated for the turbocharged F154 engine platform.
Function
The 807337 gearbox is responsible for:
- Transferring engine torque to the rear wheels
- Providing ultra-fast gear changes via dual-clutch system
- Managing torque delivery for traction and stability
- Integrating with Ferrari’s electronic differential (E-Diff)
- Supporting multiple driving modes (Wet, Sport, Race, CT Off)
Technical Highlights
Transmission system
- 7 forward gears + reverse
- Dual wet clutch system
- Electro-hydraulic gear actuation
Performance characteristics
- Lightning-fast shift times (milliseconds range)
- Seamless power delivery under full throttle
- Designed for high-torque turbocharged V8 output (~760 Nm)
Integrated systems
- Electronic Differential (E-Diff)
- Traction control coordination
- Launch control system
- Drive mode mapping (Manettino integration)
Engineering Design
Ferrari designed the 807337 gearbox specifically for the F154 twin-turbo V8, focusing on:
- High torque capacity from turbocharged engine output
- Thermal stability under repeated hard acceleration
- Reduced shift interruption for continuous power delivery
- Compact rear-mid engine packaging
The gearbox is mounted transversely at the rear, forming part of the car’s transaxle layout for optimal weight distribution.
Construction
The complete gearbox assembly typically includes:
- Transmission casing (lightweight alloy)
- Dual clutch pack (wet clutch system)
- Mechatronic hydraulic control unit
- Integrated electronic differential (E-Diff)
- Gear sets and shafts
- Sensors and actuator systems
- Oil and cooling circuit connections
Driving Impact
This gearbox is a key contributor to:
- Instantaneous acceleration response
- Stability during high-speed corner exits
- Smooth low-speed drivability (urban conditions)
- Track-level shift consistency under heat load
- Ferrari’s signature “no-lift” acceleration behavior
Known Characteristics
- OEM Ferrari complete DCT assembly
- Used across 488 and F8 generation platforms
- Integrated electronic differential system
- High-torque turbo V8 compatibility
- Motorsport-derived shifting logic
- Requires calibration after installation (ECU/TCU pairing)
Common Replacement Reasons
- Clutch wear or slipping under load
- Hydraulic mechatronic failure
- Gear sensor or position sensor faults
- E-Diff integration issues
- Accident damage or full drivetrain rebuild
