Accumulator – Ram ProMaster Dual Active Drive
The accumulator is responsible to store the pressure of the hydraulic 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 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.
Clutch Master Cylinder – Ram ProMaster Dual Active Drive
The clutch master cylinder is a hydraulic component of the clutch actuation system in the Dual Active Drive transmission. In case of a leak, the transmission may no longer properly engage and disengage the clutch. Possible symptoms include jerking during takeoff, sudden engagement of the clutch, clutch slippage, and even complete transmission failure. We sell a brand new, original Magneti Marelli part.
Clutch Sensor – Ram ProMaster Dual Active Drive
The clutch sensor (potentiometer) is responsible to detect the current state of the clutch engagement. This sensor is mounted on the clutch slave cylinder. A faulty sensor can prevent the car to open or close the clutch.
We sell an original spare part from Magneti Marelli.
Gear Sensor – Ram ProMaster Dual Active Drive
The Ram ProMaster Dual Active Drive gear sensor is responsible to detect the current state of the gear engagement. A faulty sensor can prevent the car to shift.
We sell an original spare part from Magneti Marelli.
Pressure Sensor – Ram ProMaster Dual Active Drive
The pressure sensor is responsible to detect the hydraulic pressure in the accumulator of the Ram ProMaster Dual Active Drive system. This is an original and brandnew spare part.
Pump Motor – Ram ProMaster Dual Active Drive
The pump motor drives the gear pump, which generates the pressure for the Dual Active Drive 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 Ram.
Shift Actuator – Ram ProMaster Dual Active Drive
The shift actuator is responsible for the mechanical gear shifting process. It is controlled hydraulically by the solenoid valves and is one of the most important components in the Dual Active Drive system. We sell a brand new, original Magneti Marelli part.
Temperature Sensor – Ram ProMaster Dual Active Drive
The temperature sensor measures the temperature of the hydraulic oil in the Ram ProMaster Dual Active Drive system.
Transmission Speed Sensor – Ram ProMaster Dual Active Drive
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.
