Remove pump and motor, turn coupler clockwise till the clutch housing starts to turn. If you feal something grinding at certain periods while spinning, you probably have a bad tranny. Pull it out and do the same test, if still present, you have missing teeth in the tranny spin gear, replace tranny, or install a new nylon gear and pinion gear available on this parts site.
Tranny part # AP3096209
