Replacing 727 Low/Reverse Band Pin O-Ring in Car

Thanks for the advice. I certainly considered cleaning the area around the pin and sealing with RTV but the previous owner had tried that and it either didn't work or stopped working at some point.

@Dubob - Good idea on reinstalling the pan temporarily after loosening the rear servo band, I didn't think of that.

When you say you've use a large course thread screw to the pull the pin, can you expand on that? I'm not sure I follow.
