Accumulator – Abarth 500 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.
Gear Sensor – Abarth 500 Dualogic / Selespeed
The Dualogic / Selespeed gear sensors (potentiometers) are responsible to detect the current state of the gear engagement. There are two of these sensors installed on the unit. A faulty sensor can prevent the car to engage gears or shift.
We sell an original spare part from Magneti Marelli.
Hydraulic Pump – Abarth 500 Dualogic / Selespeed
The hydraulic pump is powered by the pump motor and creates the hydraulic pressure for the Dualogic / Selespeed system. In the case of a faulty pump, the hydraulic system has no pressure and cannot change gears.
This is a brand-new, original spare part.
Oil Reservoir – Abarth 500 Fiat Idea Dualogic / Selespeed
The oil reservoir stores the hydraulic oil of the system.

Pentosin CHF 11S is especially designed for hydraulics in the automotive industry with the highest technical requirements such as in: power steering, level control, shock absorber, hydro-pneumatic suspension, stability and traction control, hydraulics for convertible tops, central lock systems, etc.
It is suitable for all extreme conditions and guarantees full performance from -40 Degree Celsius to over 130 Degree Celsius system temperature.
Pentosin CHF 11S meets DIN 51 524T3 and ISO 7308 specification standards.
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 – Abarth 500 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 Abarth.
