OK, I'm now on my third reverse switch, with a consistent problem:
After a few hundred miles, the switch contacts become high-resistance (50 Ohms or so) and the switch leaks tranny fluid, filling up the wiring boot. By the way, the last two switches were brand-new Porsche replacements. I'm running Swepco 201, by the way. Anybody have any suggestions about what might be going on? |

Did you ever remove the actuating pin? It may be in backwards, or as already stated it may be too long or a make shift replacement. I have some spare used ones if you need. This is the only common part to the whole works.
I have some good used switches, too. |

I'll take a look at it and see if it's got a problem. Hey, since you know everything about 901s, where is the vent located? Is it possible that the vent is plugged, thus pressurizing the case and forcing oil out of the switch? |

Not impossible, I guess, but I have never heard of it and it would be pretty dang hard to do (IMG:style_emoticons/default/smile.gif) Yes, you fill the box until the oil reaches the fill hole. Do you have the crush washer under the switch? Its pretty thick and without it you can destroy your switch and have leaks. |
