kenmore series 90 wont spin or drain?

the machine will go through the cycle and stop after the wash with the tub full of water. I turn it off and spin to the spin cycle and nothing happens. I do this a few dozen times, give up , come back and try it again and it starts the spin cylce and drains. It never rinsed it so set to rinse and it fills up and agitates and then stops before it gets to drain and spin. so I am not using anymore until I figure out if its the bushes? or what that is not letting the dial advance to the rinse spin cycle. There is no noise when it stops, so that makes me think it is some contact or sensor??
