DB9 Auto goes from P to N on startup

[DapperDanMan]

A few months back noticed this happening. Start the car and the gearbox goes from P to N. The car is on a level surface (no strain on parking pawl) .

The car functions correctly afterwards and goes back into Park using the button.

Battery is good and is kept well charged. Any ideas?

FYI

My battery went the other day without warning so I replaced it and the problem described above has disappeared. I cannot say whether the battery being disconnected or the battery being in a state of degrading performance causing a reduction in voltage to the cars electronics was the cause.

The car until failure showed no other signs that the battery was faulty, it started well and took charge.

So if you ever get the problem maybe try a battery disconnect first (taking appropriate steps to ensure you know how to reset things once reconnected) and if that fails have your battery tested.
