Check the fluid and all the wiring plugs going to the transmission.it is not uncommon for oil to drip onto a plug and cause bad readings,or vacuum lines that are cracked.

Tips for a great answer:
The IPC detects a loss of serial data communications with the ECM. The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
The automatic transmission shift lock control solenoid
The automatic transmission shift lock control switch
With the ignition in the ON position, voltage is supplied to automatic transmission shift lock control switch. Voltage flows through the normally closed contacts of the automatic transmission shift lock control switch to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid is permanently grounded. This energizes the automatic transmission shift lock control solenoid causing the transmission shift lever to be physically locked in the PARK position. When the brake pedal is pressed the contacts in the automatic transmission shift lock control switch open, de-energizing the automatic transmission shift lock control solenoid. This allows the shift lever to be move out of the PARK position.
The transmission range (TR) switch is part of the park/neutral position (PNP) and backup lamp switch assembly, which is externally mounted on the transmission manual shaft. The TR switch contains four internal switches that indicate the transmission gear range selector lever position. The PCM supplies ignition voltage to each switch circuit. As the gear range selector lever is moved, the state of each switch may change, causing the circuit to open or close. An open circuit or switch indicates a high voltage signal. A closed circuit or switch indicates a low voltage signal. The PCM detects the selected gear range by deciphering the combination of the voltage signals. The PCM compares the actual voltage combination of the switch signals to a TR switch combination chart stored in memory.
You need a Tech2 scan tool to diagnose this problem ! possible range sensor !

The automatic transmission shift lock control switch
Can you or can you not take it out of park ?
Shift Lever Does Not Move with Brake Pedal Depressed
yes or no ?
The instrument panel cluster (IPC) displays the selected gear position as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the gear position. The PRND321 display blanks if:
The ECM detects a malfunction in the transmission range switch circuit.
The IPC detects a loss of serial data communications with the ECM.
You have a transmission range sensor or PCM problem , Need a professional grade scan tool to diagnose the problem , well that would be the easiest way to test .You should have all modules test for DTC'S - diagnostic trouble codes ! That would point you in the right direction ! I would suggest you google class 2 serial data communication network !

Now i dont know a lot about automatics especially modern ones with all this fancy electronics thats used nowdays but i think its a fault with the temperature sensor for the gearbox.But where its located and what it looks like i have no idea it could even be mounted inside the gearbox .Sorry not a very good answer from a mechanic but?? very few of our europeon cars come with auto transmission .Evan when i do know whats wrong i cannot buy the parts for the gearbox as only re-con boxes supplied by the dealer so best advice is to try a specialist in auto box repairs only .PS some of my best students when i used to teach mechanics many moons ago were the girls so no excuses like iam only a girl please

Trouble Code Conditions:
Engine started; vehicle driven in a forward gear, and the PCM detected that the O/D Pressure Switch circuit indicated open or closed at the wrong time.
Trouble Code Conditions:
Ignition on or engine started. The PCM received a message over the CCD Bus from the Transmission Control Module (TCM) that it had detected a problem and set a trouble code in memory.
