gearbox

Hi, I have a RUG-BG1 toploader originally from a Torino I believe. There is a feature that has access to a detent and I don't know what part goes into it. Most of the drawings show a detent bolt but this is not threaded. Can anyone help?

Hi all, I recently just picked up a ba falcon and when i went to put it into tiptronic the dash says performance and then when I down shift and up shift it just switches between adaptive and performance without actually going through any gears. Though when I drive the car normally in either mode...
