Accumulator – Fiat Dualogic / Selespeed
The accumulator is responsible to store the pressure of the hydraulic system for later access by the actuators. The membrane type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a gas to create counterpressure. Both cells are separated by a membrane. These accumulators have a certain life span and a common defect is that the gas leaks out of the cell, which causes the system to be unable to build up hydraulic pressure. In many of such cases, the pump appears to prime permanently.
We offer the brand new original Magneti Marelli spare part.
EV0 Clutch Solenoid Valve – Fiat Dualogic / Selespeed
The EV0 Solenoid Valve is responsible for the clutch actuation of the Selespeed system. A faulty EV0 can cause problems while engaging the clutch (for example shuttering) and in consequence the car refuses to change gears.
Please note: The product photo is for illustrative purposes only. The valve may be supplied without a sticker label. Depending from model and year of construction the numbers on the sticker label of your original valve may vary. In case you are not sure if our part fits, please contact us before you buy.
EV1 / EV2 Engagement Solenoid Valve – Fiat Dualogic / Selespeed
The Engagement Solenoid Valves are responsible to engage the gears of the Dualogic / Selespeed system. In the case of failure of this valve, the car will refuse to go into one or more gears.
EV3 / EV4 Selection Solenoid Valve – Fiat Dualogic / Selespeed
The Selection Solenoid Valves are responsible for selecting the gears of the Dualogic / Selespeed system. In the case of failure of this valve, the car will refuse to go into one or more gears.
Pressure Sensor – Fiat Dualogic / Selespeed
The pressure sensor is responsible to detect the hydraulic pressure in the accumulator of the Dualogic / Selespeed system. This is an original and brandnew spare part.
Pump Motor – Fiat Dualogic / Selespeed
The pump motor drives the gear pump, which generates the pressure for the Dualogic / Selespeed transmission. Both parts together form the hydraulic pump. Without hydraulic pressure, the transmission cannot perform any action – neither change gears, nor operate the clutch. Therefore, the hydraulic pump is the most important component in the system.
In most cases, it is sufficient to replace only the electric motor, as this is a wearing part. The gear pump fails only very rarely. Another advantage is that when only the pump motor is changed, the hydraulic system does not need to be bled afterwards, unless it has been opened.
We sell an original, brand new Magneti Marelli spare part – the same part you would get from Fiat.
Selection / Clutch Sensor – Fiat Dualogic / Selespeed
The Dualogic / Selespeed selection and engagement position sensors (Potentiometers) are responsible to detect the current state of the gear engagement. The clutch sensor is responsible to detect the state of the clutch. There are three of these sensors installed on the Dualogic / Selespeed unit. A faulty sensor can prevent the car to engage gears or shift.
We sell an original spare part from Magneti Marelli.
Shift Actuator – Fiat Dualogic / Selespeed
The actuator is responsible for mechanical gear shifting in the transmission. It is controlled hydraulically by the other solenoid valves in the system and by the solenoid valve installed on the actuator itself and is one of the most important components in the Selespeed system. We sell a brand new original part.
Transmission Speed Sensor – Fiat Dualogic / Selespeed
This sensor provides the speed signal of the transmission input shaft. The speed signal is required by the control unit to control the transmission system, adjusting properly the shaft speeds before engaging and disengaging the different gears.
