I have a Kenmore Series 80 washing machine that does not spin and makes a terrible noise that sounds like a gear slipping when in the spin cycle. The door switch appears to working properly. After reading several post I was certain it would be the coupler but upon inspection found it (the coupler) was not broken. I did notice that when I move the coupler manually the motor and wheel in the pump move freely. The shaft coming out of the transmission however does not move when I move the coupler. I can move the shaft manually in either direction and wonder if the transmission is the problem. Any help would be appreciated.
