I have an '02 diamante with 100k miles and the N light is flashing. Manual says check transaxle. Brought it into mechanic. No word yet. Car is drivable now and I can go up to 50 mph without any problems. Only thing I really notice is I don't fell the car shifting when I accelerate like I use to and when I take my foot off the brake at a light it doesn't jump to go witgh any power but moves a little bit. Any thoughts on problems? Cost to replace/repair? Thanks!!
