1985 300TD - Mysterious Intermittent Starting Problem

9 times out of 10 my car starts immediately no problem. 1 time out of 10 there is a click and then nothing. After several attempts I can get the car started and then everything is OK for a couple more days...

Here's the mystery. I had my shop check the solenoid (OK) and replace the ignition switch using the kit sold on this site. Everything was fine for a couple of days, then the same problem occurred. We can almost live with the problem but I'm concerned that one day we won't be able to start it at all.

1980 300D "passing" gear and faint whistle when turning right

If I push on the accelerator with only modest pressure (especially when the car is cold), it often jumps into what I assume is a "passing" gear. I've dealt with the problem by just being cautious with the accelarator - often, I just let up on the gas when I hear it jump into "passing" mode, but I was wondering if there's a repair I can try.
