Iím having an issue with the gearbox, when the ignition is on - the car does not go into auto or reverse.
On the dash, it just displays neutral.

I disconnected the battery for half an hour and reconnected it. Before I turn the engine on, the car will go into Auto and Reverse. I hear the clutch actuator move and the dashboard displays A, N and R accordingly.

However as soon as I start the car, the problem occurs and it stays in Neutral.

Any suggestions on what could be causing this?
