F1 & E-Gear Actuator Rebuilding

GTE Engineering inspects and rebuilds applicable electrohydraulic gear-selection actuators used in Ferrari F1, Lamborghini E-Gear, Maserati Cambiocorsa and Aston Martin Sportshift (ASM) systems. The actuator operates the gearbox selection mechanism; the hydraulic power unit supplies pressure. They are different components and must be identified separately when requesting a repair.

What these systems do

An automated manual combines a mechanical gearbox and friction clutch with electronic control and hydraulic actuation. Paddle inputs and the control module command clutch and gear movements. This differs from a torque-converter automatic and from a dual-clutch transmission (DCT). Ferrari F1, Lamborghini E-Gear, Maserati Cambiocorsa or DuoSelect, Aston Martin Sportshift (ASM), Audi R tronic and Alfa Romeo Selespeed are application-specific names; they do not imply interchangeable parts.

Actuator, power unit or complete gearbox?

Gear-selection actuator: hydraulic valves and mechanisms move the gearbox selector; position feedback helps the control system verify movement.
Hydraulic power unit: pump, motor, pressure storage and associated components supply the operating pressure.
Clutch and release system: friction components, bearing or slave cylinder, hydraulic connections and clutch-position feedback determine clutch operation.
Mechanical gearbox: gears, bearings, shafts and synchronizers require a separate assessment.

Symptoms and diagnosis

Gear-selection warnings, delayed shifts, loss of selection when hot, pressure loss or clutch engagement problems can have multiple causes. Wiring, supply voltage, fluid condition, leaks, clutch wear and mechanical faults must be checked alongside the hydraulic assembly. A fault code identifies a diagnostic direction; it does not prove that every named component requires replacement.

Rebuild scope and verification

GTE evaluates the received assembly, inspects serviceable components and proposes the necessary repair. Replacement valves, sensors, hoses, accumulator, motor or mechanical parts are included only when specified in the approved estimate. Applicable component checks follow the agreed work. A bench assessment cannot reproduce every vehicle-side electrical, mechanical or operating condition.

What to send with your inquiry

VIN, model, year and transmission type.
Clear photographs of the complete assembly, identification labels and connectors.
Fault codes, hot/cold symptoms, diagnostic findings and previous repairs.
Whether the request concerns the actuator, power unit, hoses, clutch or complete gearbox.

Installation and calibration

The installer must follow the correct model-specific filling, bleeding, selection-learning and clutch setup procedures. A rebuilt actuator does not complete vehicle diagnosis or automatically correct a worn clutch. Confirm the applicable instructions with GTE and use the technical resources linked below.

Common questions

Is this a replacement unit?

A send-in rebuild normally concerns your existing assembly. The individual product listing or estimate defines the supply arrangement.

Are all F1 and E-Gear units the same?

No. Match the vehicle, installed assembly and reference number before ordering. Similar appearance or shared system terminology is not proof of fitment.
