New Selespeed Robot Motor Fiat Lancia

The component with OE code 71769597 is an electric motor coupled to a hydraulic pump, used in the automated transmission systems Selespeed and Dualogic fitted to various vehicles of the Fiat group. This module is responsible for generating the hydraulic pressure necessary to operate the robotized gearbox assembly and the clutch actuator, replacing the driver's mechanical input.

Technical specifications

The OE 71769597 pump motor is a compact unit composed of:

• 12 V electric motor
• Gear-type hydraulic pump
• Aluminium housing with mounting flanges
• 2- or 3-pin electrical connector
• Operating pressure: approximately 40–50 bar
• Cyclic operation managed by the transmission control unit (TCU)

DIPA can overhaul these modules thanks to its experience and expertise.

Functions

The electric pump module functions to:

• Generate oil pressure for the transmission hydraulic actuators
• Allow gear engagement without using the clutch pedal
• Ensure correct operation of the Selespeed/Dualogic transmission
• Interface with pressure sensors and the transmission electronic control unit

The correct operation of the pump is essential for building and maintaining pressure in the control circuits. If pressure is absent, the gearbox enters emergency mode and will not allow gear engagement.

Make and models on which the part is mounted

The OE 71769597 pump motor has been used on numerous FCA group models equipped with robotized automated transmissions:

Fiat

• 500
• 500 C
• Panda
• Panda Van
• Punto
• Punto Evo

Lancia

• Ypsilon
• Musa

DIPA recommends always checking compatibility based on the specific engine code and chassis number (VIN).

Faults and causes

The most common failures found on this component include:

• Electric motor wear: leads to loss of power and absence of pressure
• Inefficient hydraulic pump: produces insufficient pressure or abnormal noise
• Continuous start cycle: the pump activates too frequently to compensate for internal leaks
• Electrical communication error: caused by corroded connectors or an interrupted motor
• Blown fuses or excessive current draw: a symptom of short circuits in the motor

In many cases it is possible to replace only the electric motor without intervening on the entire hydraulic assembly, provided the internal pump is efficient.

Possible associated DTCs

In case of pump or motor malfunction, the control unit may record the following error codes:

• P1743 – insufficient hydraulic pressure
• C1555 – transmission hydraulic pump fault
• U1706 – loss of communication between the transmission control unit and the pump module
• P1742 – pump motor locked or not activatable

Final conclusions

The OE 71769597 pump motor is a central element of the robotized transmission system fitted to numerous Fiat, Lancia and Alfa Romeo vehicles. Its failure compromises the gearbox operation, rendering the vehicle unusable.

DIPA has a wide range of spare parts: from original parts to aftermarket ones selected from the best manufacturers on the market. Moreover, it offers reconditioned components with near-new performance, which provide savings on replacement and contribute to environmental protection through the circular economy.
