well it won't start in any gear except "Park".

 

From the manual for the ZF:
Transmission Position Sensor
The TCM uses the position of this switch housed on the TCM and main control valve body, to determine the selected gear range on the Automatic side of the selector lever. The selector lever is connected to the transmission by a cable, which operates the transmission selector shaft between positions Park, Reverse, Neutral and Drive. The TCM detects the driver’s choice of manual range selection (+ or -) by means of a 3-bit code
generated by the printed circuit board (PCB) housed within the selector assembly. This 3-bit code is then transformed in to a CAN message by the PCB and transmitted on to the CAN bus where it is detected by the TCM.

The TCM uses this information to generate the CAN message "Gear Position Selected", which must not be confused with the similar message "Gear Position Actual" indicating the current mechanical gear ratio activated by the TCM.

Position Sensor Monitoring

The TCM can identify errors with the position switch located within the transmission. If an unrecognized position code is read by the TCM a plausibility fault will be logged. (A code is checked between positions).

 

I'd say you've got a CAN communication fault more than anything else, which could be caused by a short-curcuit or a fault on the CAN circuit which will require an auto-elec to diagnose/fix.
