The shifter in my convertible seems to have a few issues. First, it is missing the little cap with the shifter pattern. Second, it feels like the knob itself is a bit lower compared to the lever. I do not know if it is related or not but I am having no problems with going into reverse without having to pull the ring underneath the shifter knob. FYI, this is all begin done while the car is off. What should I check for?
