When I turn the ignition to the run position, the trans indicator on the instrument cluster panel (meter assembly) works fine. Every gear I shift to, shows up on the panel. If I shift it to "N" or "P" and start the engine, it stays stuck on that "N" or "P" light. I have already changed the A/T control module (mode sensor) and think it might be the multi-plexed indicator control unit or the powertrain control module (PCM). Any idea or thoughts would be greatly appreciated.
