When the system volts get low the transmission goes into limp home mode -
as you've discovered. Correct the system volts (alternator fault?) and the
transmission will return to normal.

A voltmeter connected across the battery with the engine running will soon
show how things are - it should read approx 13.8 volts. Anything under 12
will result in limp home mode.

It is fixed.... Disconnected battery then reconnected battery, so that
the 'default' or 'Limp home' mode is deselected.
Now I can dice and drift again, HAHA

You need to find out why this happened. It may just be low volts and all
you need is a long run or a new battery, or it could be more serious.

The OP said there was a battery problem with low volts therefore being
inevitable.

Indeed.

So if it is dropped the lid stays on and the contents inside. The
alternative: -

could be described as embarrassing to say the least!
