The transmission warning light on my VZ Holden Calais comes on, seemingly at random. My mechanic has checked the system and says that all is ok, and when I turn the ignition on without starting the vehicle the system check comes up ok, but the light still comes on at times. Any thoughts on what the cause might be? I am about to have the transmission serviced with a change of oil to see if this corrects the problem.
If the transmission is performing as it should then it could just be a dodgy wiring connection, but having the transmission checked and serviced is a wise course of action.
