What is a wig-wag on a transmission

I think its something that controls the tranny

When my washer goes bang when it starts spinning is that the soilenoid ?

On a belt drive whirlpool built machine (kenmore, inglis, whateva) the wig-wag is the solinoid on the transmission that controls agitation and spinning. It got the endearing name "wig-wag" because it swings back and forth in time with the agitator.

"When my washer goes bang when it starts spinning is that the soilenoid ?"

The belt drive normally make this kind of noise when they shift to spin. Is this a new or recent problem? If it is a new problem, then it may have to have more attention. If not, it is probably normal.

Ooops i for got to state that this is a dd

DD's don't have wig-wags. A clunk noise is normal on a dd after the pause after draining when the motor reverses and shifts to spin.
