407 Coupe 2.7L HDi stuck in park

[ta1te]

Just writing to see if anyone has any solution to taking my 2.7L HDi out of park.

We are being fronted with “automatic gearbox programme fault” with ignition on, and the car will not start. We do not know of any shift lock release button so any information or tips would be super helpful on how to get the car into neutral. Thank you.

Is that with the 6 speed Aisin box? The selector lever comes with the transmission.

It has been a topic many times in the Citroen forum, eg:

Thread 'C5 X7 shift lock sticking'

Jun 24, 2019

Shift lock on my 2009 X7 has been sticking over the past few weeks. Not sure as yet if it's the relay or the locking pin itself. I have prised out the fascia to check the pin I'm not sure if the selector knob can just be pulled up and off or if it's secured some other way. I've given it a bit of a tug but I don't want to pull too hard and break something - how is the knob removed?

You need to pull back the trim and use a screwdriver to move the lock at the right front.

There are several reasons for the lock sticking closed, such as low battery voltage, the lock itself failiing, and the transmission computer not releasing it.

I should have added. Release the lock, but get the OBD code read. If the transmission ECU is not releasing it.
