Several times as of late, on startup, but not every time, the car starts normally, but when I put my foot on the brake and then try to shift into reverse, I cannot push in the button on the shift knob. I then wait a few seconds and try again, and then it shifts normally. I noticed that the tracs light on the dash goes out right when it wants to shift normally.

Any ideas?

Thanks in advance.
