First off, hello! I'm new here, friend of mine told me to join after I bought my first car, a Ford Mondeo Ghia X!

The car I just bought got a flashing overdrive light after driving it for 5 miles from the dealer I bought it from. The manual states that this indicates a transmission problem. I'm told that this could either be that the transmission is low on oil or has a real problem in which case it would be best to replace it (relative easy as it's an automatic).

Also the pedometer is stuck. Either genuine stuck or messed with by a previous owner. Is this something that is easy to be repaired? Obviously it means missing miles but it would be a good start to begin counting again.

Before anyone states the obvious, trying the dealer to take it back but he's not being helpful so thinking of plan b, resolve any issues and enjoy the car as it is a good nick (apart from transmission flickering light).
