I am the new owner of a 67 firebird convertible. When I bought the car, I could have sworn that you had to press the shifter button in order to shift gears. Immediatelly upon buying the car, I had the transmission serviced and a couple other nits tended to and now the shifter freely moves between all gears without pressing the shifter button, even out of park.

Repost from general - thanks in advance.

I did a search a while back, and while I can't find the post again, I thought I came across some postings discussing that this problem could be a loose cable in a 67.

I haven't been back to the mechanic yet, but he claims that there is no cable between the shifter and transmission and that the shifter must be broken and need some internal rebuilding. Any thoughts or pointers would be greatly appreciated.

I don't think the 67's used a cable. I think it is a rod. If the shifter is moving without pushing in the button I would think that the shifter handle is dirty or rusted inside and is not letting the button to come back up.

See my reply on the other message thread. You are going to need to take the shifter apart (and pull the console if you have one) to see what the issue is. It could be several things.

you can pull the plastic button off and verify the sleeve and spring inside the chrome sleeve is working.
