Ford Transit Durashift ASM

New clutch / selection solenoid valve for the Ford Transit Durashift / ASM. There are two of these flow-proportional solenoid valves on the hydraulic unit: one for clutch control and another one for gear selection. If one of these two valves fails, the Durashift / ASM system can no longer correctly open and close the clutch or shift gears.

The pressure accumulator is responsible to store the pressure of the hydraulic system for later access by the actuators. This piston type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a Nitrogen gas filling which creates the counterpressure. Both cells are separated by a moving piston. Typical symptoms of a faulty pressure accumulator are frequent and short pump cycles. If there is no more preload pressure left in the accumulator, the pump runs every few seconds, which ultimately leads to a consequential damage of the pump motor. Along with the pump motor, a faulty pressure accumulator is one of the most common causes of pressure build-up issues and is one of the few wear parts in the system that should be regularly checked and replaced if necessary.

We offer a brand-new replacement accumulator.

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.
