Do you see the silver clutch turning when it should be spinning in the spin cycle?
You'd have to jump the lid switch so the washer will spin in the spin cycle, this link shows you how to do that:
Bypass Direct drive washer lid switch from consol plug
The silver clutch is just above the gearcase.
If its not turning, your gearcase is shot.

If the silver clutch is tuning and if your motor coupler looks fine, then you'd need a new clutch. Whenever I replace the clutch I always replace the basket drive assembly as well, as they both work together.
