Symptoms of bad speed sensor?

Aside from a "jumpy" speedometer, does anyone else know the symptoms
of a bad speed sensor? My speedometer sometimes jumps and I have
recently noticed my transmission is acting strangely. Sometimes
when I turn and it downshifts- it will jerk a little. Sometimes it
shifts fine. Sometimes upon heavy acceleration- it will try to
shift to higher gears before it should. Is this a bad problem with
my transmission, or could the speed sensor be causing this? By the way- my car has 245K highway miles. Thanks.
