guys need help, mates zafira is throwing fault code P0700, and has what seems to be an active transmission fault code from somewhere between the main ecu and the transmission ecu ( possibly turbine sensor or rpm sensor in the box if it has one )

does anyone have a wiring diagram for this 2002 model car? i would start with resistance testing from the main ecu to the box and gearbox control unit.

is the geabox a zf? the selector on the floor seems mechanical so is there a solenoid shift set up or a hydro mechanical shift valve?

anyway a wiring diagram would be a good if anyone has one.

thanks in advance
