I have a 29 coupe that I rolled out of the garage by hand this morning. I pulled it out backwards and it was in gear so I went back up and pulled it into neutral and rolled it the rest of the way out. It now seems the gears are bound and I cannot get it to transmission it into third. I have rocked it in reverse, 1st, and second. Nothing is working! I have hours before it is leading a parade. Any ideas or suggestions.
