Having problems with your 1998 Mercury Mystique ?
NO OVERDRIVE I recently bought a 98 mystique and it won"t shift into OD. sometimes the OD off light flashes and if I am going 65 on the highway my rpm is about 3500
I had a similar problem with my 98 mystique when i bought it used. I had no overdrive and was lucky to find a honest transmission shop that found the problem. In my case the overdrive was unplugged. They plugged it back in,cleared the computer and changed my tranny fluid and i was good to go. You should be revving about 2400rpm at 65mph. The other thing you can check is to make sure that the wires that go from the overdrive button are not broken off or coroded.
