I recently bought a 1984 300D. I have noticed I can move the gear shift (US auto) up and down without the car started. I believe you shouldn't be able to do this. Also where reverse is located the shifter is between Park and Reverse. Anyway I think this causes the car not to start. I can get it started no problem, run an errand, and when I hop back in it won't start. I can try to start it 5 or 6 times and it won't crank (normal glow light and buzzer). So I did an experiment and put it into N and it started right up. I did this a couple of times. Is there a gearshift switch and if so is there an adjustment to fix this problem? Thanks
