55250921 CFC328F.02 – Selespeed Gearbox Control Module Fiat 500

55250921 / CFC328F02 is an original Selespeed gearbox control module used in Fiat 500 models equipped with the automated manual Selespeed transmission. The module is responsible for full control of gearbox actuators, gear shifting, clutch operation, and communication with other vehicle systems (including engine ECU, ABS, Body Computer).

The most important selection criterion is compatibility by part number. If your module shows number 55250921 or system designation CFC328F.02 / CFC328F02, the offered control unit will be hardware compatible.


Technical specification

  • OEM number: 55250921
  • Manufacturer designation: CFC328F.02 / CFC328F02
  • Transmission type: Selespeed (automated manual)
  • Application: Fiat 500
  • Condition: fully tested, bench-tested on diagnostic station
  • Warranty: yes

Application – compatibility by part number

The gearbox control module 55250921 CFC328F.02 was used in:

  • Fiat 500 1.2 8V (169A4.000) – approx. years 2008–2015
  • Fiat 500 1.4 16V (169A3.000) – selected versions with Selespeed transmission
  • Selected European market configurations with semi-automatic gearbox

Function of the Selespeed gearbox control module

The CFC328F.02 module is responsible for:

  • clutch actuator control,
  • managing gear selection and shifting,
  • control of the hydraulic system pressure,
  • CAN communication with other vehicle modules,
  • automatic and manual (sequential) mode.

Failure of the control module may manifest itself as: inability to change gears, gearbox emergency mode, CAN communication errors, jerking during take-off, or transmission fault message.


Why is compatibility by number 55250921 crucial?

In the case of Selespeed transmissions, the same car model may appear with different control unit versions. Therefore:

  • we do not select only by car model,
  • we do not select only by production year,
  • we always verify by OEM number from the module label.

If your control unit is marked CFC328F02 and number 55250921, this unit will be the correct choice.
