[Mgs] Flat towing

[Paul Hunt]

The oil is shared between OD and gearbox.  The OD has its own pump and that 
and the gearbox 'pump' will be driven when towing as long as the OD is 
working correctly.  If there is a fault which means the car free-wheels with 
OD switched out then neither pump will be driven.  Oil level also needs to 
be correct.
