I got a stage iv suncoast and has been working great for 6 months. Tonight the gear shifter indacator (i guess thats what it is called) is not showing that it is any gear. Reverse always lights up and 1st gear will show. When i am going down the road the D light will box around it and then it will go back off. The transmission is shifting reasonably good with only a few knocks and bump but nothing too crazy. Any help appreciated.
