I drove my wife's car last night and discovered that the problem she had told me about seems more serious than she indicated. The car will start out in first gear just fine and then shift to second, but remains in second-- it will not shift to third no matter how high the RPM's are.
I'm going outside this morning to verify the fluid levels are correct.
I do not know if it matters, but the button on the left side of the shifter (performance shifter button?) appears to have been broken inside the shifter housing----it just fell off into the floor 2 weeks ago.
Is there something I can do as a do-it-yourselfer to fix or at least further diagnose the problem?
