Here's a new problem: Again an intermittent problem. I'll be driving down the road and the speedometer goes to zero and than back up and the trans. goes back into gear. I originally thought it was a trans problem, but I have an old cell phone that is powered up by the ignition key that is still in the car. When it powers up, it beeps. And every time this has happened the phone would beep. Didn't really connect the two until recently. I don't have a trans problem, I think I loose power for a very short time and that's what shuts everything down and then restarts it. It happens very rarely, and I haven't noticed anything that might cause it, like going over a bump. (thought it might be a loose wire). There are no codes generated.
any ideas, thanks, nick
