I have a 1997 406 automatic. Occasionally and usually when first starting up the auto box goes into 'get you home mode' ie. stays in 3rd with the two dashboard orange indicator lights flashing. After a short drive I can usually clear in by turning off the ignition and setting off again. It seems to do this more often when the car has been parked in hot sun (not that hot though, I lived in London....). On every other occasion the box works fine, although its a high mileage car at 88k. The fluid level is ok. So mechanically the box seems ok but presumably a sensor somewhere occasionally thinks otherwise. The sun heat part of the symptom seems unlikely I know but nevertheless it does seem to b e part of the equation. Anyone got an idea what the problem is? What sensor it might be and where is it? Thanks in advance. S
