Automatic Gearbox Lever

[Guest alipatch]

Hi,

I'm looking for help - I have a C5 2.2hdi auto (2002) occasionally when I start the car and after depressing the brake pedal(there is no 'click') so the auto gear lever jams - I can switch off the engine, wait for a few seconds, re-start the engine and it works OK! again - this happens fairly frequently - is there anyone out there with a fix? as it's getting quite bothersome.

Next time it happens if you can keep the pedal pressed and see if your brake lights are on as the brake light switch tells the ecu to unlock the gear selector. if all is fine there then you need to be checking the shift lock switch on the lever itself. I would be having a good look at the wiring as with it being a inermitant fault it could just be a loose wire. Anyway heres a bit info on how to get it out of park if the fault becomes permenent

 

 

SHIFT LOCK

The shift lock is a system which locks the gear selection lever in the park position «P».

Unlocking the «shift lock» (normal operation).

Switch on the ignition.

Apply the brake pedal and keep it pressed.

Using the selection lever, disengage from position «P».

Unlocking the «shift lock» (with a fault).

NOTE : It is impossible to unlock the «shift lock» with the « normal operation» method.

The causes of the fault may arise from the following components :

- «Shift lock».

- Gear lever position switch.

- Automatic gearbox ECU.

- Electrical harnesses.

- Battery voltage.

Remove :

- The gear lever knob (1) by pulling upwards.

- The cover (2) (unclip).

- The shutter.

Unlock the «shift lock» (4) using a screwdriver.

Using the selection lever, disengage from position

 

keep us updated please

Take a look at this link, it shows pics of the access to the wiring harness, but deals with a common failure (at least here in Australia), yours might be showing early symptoms?
