I saw your post about the wrench/powertrain light coming on. Last Saturday, 03/22/08, I was driving on the highway and I noticed my speedometer wasn't working. Then I noticed that the front airbag light was on. When I got off at an exit, I also noticed that the wrench light and low tire pressure light was on. When the light turned green, I started to accelerate and the car would hardly go - it felt like the transmission was not shifting. It gradually started to go and go up to speed. However, every time I had to stop at a light, it would barely go. When I got home, I restarted my Edge to see if everything was still the same. All the lights that had been on were off, however, my speedometer was still not working and it was still not wanting to go when I put it in drive. The next morning I took it to the shop and, of course, after I had driven only a short distance everything seemed fine. I still don't have my car back. They had to have a transmission specialist look at it. Supposedly, there is a sensor that needs to be replaced as well as some other parts that are transmission related. I'm a little concerned about whether it will really be fixed when I get it back.
