1.9 diesel - auto trans - no reverse gear - will go forward. Before I take it to garage, could it be lack of fluid?
If that’s all OK then check all the electrical connections of the gearbox, remove each connector in turn and spray with contact cleaner. Check that the wiring to the gearbox is in good condition with no chafing or frayed wire
Where do I find the solenoid?
As the solenoid is accessible I do not have to scrap the vehicle.
