Accumulator – Alfa Romeo 147 156 GT Selespeed
The accumulator is responsible to store the pressure of the Alfa Romeo Selespeed system for later access by the actuators. The bladder 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 fail is that the gas leaks out of it's cell which makes the system unable to store pressure. In a lot of such cases, the pump appears to prime permanently. We offer the brand new OEM part.
EV0 Clutch Solenoid Valve – Alfa Romeo 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. Photo for demonstration purpose only. The valve may come without sticker label.
EV1 Engagement Solenoid Valve – Alfa Romeo Selespeed
The Engagement Solenoid Valve EV1 is responsible for engaging odd gears 1-3-5 of the 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 – Alfa Romeo Selespeed
The Selection Solenoid Valves EV3 and EV4 are responsible for selecting the gears of the Selespeed system. In the case of failure of this valve, the car will refuse to go into one or more gears.

Pressure sensor – Alfa Romeo Selespeed
The pressure sensor is responsible to detect the hydraulic pressure in the accumulator of the Selespeed system. This is an original and brandnew spare part.
Pump motor – Alfa Romeo 147 156 GT Selespeed
[tabs] [tab title="The problem" start=open] The pump supplies the hydraulic pressure for the different consumers (actuators) of the Selespeed and stores it in the pressure accumulator. The pump consists of a small gear pump and the powering electric motor. Depending on the year of construction, the electric motor used by Alfa Romeo is a vulnerability and likely to fail due to its location in a high temperature area. [/tab] [tab title="Our motor"] Our motor comes directly from the original equipment manufacturer (OEM) of the Selespeed system. Various car manufacturers purchase their parts directly from this supplier. The motor meets highest expectations of quality and enables a sporty style of driving with frequent shifting. [/tab] [tab title="Installation"] The motor can be changed easily as it is only attached by two screws to the pump head. It is not necessary to remove the entire pump but however sometimes helpful.

Selection / Clutch Sensor – Alfa Romeo Selespeed
The 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 Selespeed unit. A faulty sensor can prevent the car to engage gears or shift. We sell an original spare part from Magneti Marelli.
