I think I have diagnosed the most recent problem with my Land Rover. The M and S lights sometimes come on flashing on the dashboard and the car goes into limp mode (like 4th gear). It happens after I start it and try to back out of the driveway or sometimes leaving a parking space at a shop. Usually I turn off the engine and restart it and it may or may not happen again. It seems to be worse since I began using my AC again and that usually means that the AC drain line is leaking into the Neutral Safety switch on the side of my transmission. The switch is $700 from Land Rover and about $450 from some internet shops. I found a used one on eBay for $140 that comes with a 60 day gaurantee so I bought it. Sometimes the issue is caused by a bad battery or alternator or connection but I had mine tested and it's all fine so on a hunch I will try to replace the switch.
