When to change Comfortmatic gear actuator fluid?

[In a Pickle]

I have searched the internet and Fiats own servicing schedules extensively but this one is eluding me.

This is not the gearbox oil nor the hydraulic clutch fluid.

The gear ACTUATOR has its own hydraulic fluid, can anyone advise when this should be changed?

Thank you!

I believe on a lot of hydraulic systems you only need to change the fluid if it becomes contaminated, is there a filter associated with this.

The Ford car I had with a robotised manual used servos directly on the same gearbox linkage that you'd use if you were rowing the stick on the manual. Does the Fiat Comfortmatic use hydraulics?
