📝 Item Description

Genuine Alfa Romeo/Fiat automatic transmission powertrain management unit manufactured by Magneti Marelli. This CFC 8TDF.01 module manages the shifting actuator solenoids, clutch engagement maps, and fluid hydraulic logic on C635 dry dual-clutch systems. The original sealed aluminum body is structurally sound. Both primary wire harness socket receiver banks are clean, perfectly straight, and clear of moisture damage or corrosion.

⚠️ Condition & Fitment Notes

• Condition Note: Premium salvaged car part. The factory identifier label is fully intact and readable. Internal circuits have been verified through diagnostic bench-testing.

• Ideal For: Replacing a failed or water-damaged TCM that triggers a "Check Transmission" dashboard light, causes a complete failure to engage gears (stuck in neutral/park), or yields hard microprocessor internal failure codes.

• Important Note: Following installation, this unit requires a Proxi Alignment procedure via an FCA-compatible diagnostic scanner (like WiTECH) to sync with the vehicle's central CAN-bus, followed by a clutch calibration and self-learning reset routine to ensure smooth shifting engagement.

🛡 Warranty

• Warranty: 1-month replacement warranty covering module electronic component and logic board faults.
