Eric,
In my shop notes I had the following information from just 2 years ago. This numbers was good for 62, 63, 64 pushbutton 727 trans, but I can't find it to photograph.
NAPA #727-2112.....O-Ring seal trans cable

Anyone know what size the o-ring is?
Pan looks a little warped. Will a regular 727 aftermarket pan fit?
