Ihave a wtw5300sqo it agitates but very slowly

I would have a look at the cam dogs located in the agitator and the motor coupler or belt if not direct drive. check for loose clutch or slipping tranny. also check for worn agitator spline

The grease seal on the agitator/washer transmission has failed. The agitator is held in by one bolt/nut on the top of drive shaft under the plastic cover, which can be glued down and hard to remove.

I would check the agitator dogs, as they are called. More than likely they need to be replaced.

Hello,for your machine to agitates slowly, the problem is probably the agitator dogs or coupler is probably bad.
The agitator dogs are located inside the agitator and the coupler is the one that connects the motor to the agitator.
Thanks

Agitator coupling is worn out. Replace coupling underneath the agitator (WH43X10032)

not a good number go to whirlpool parts surplus dot com and ask for mark i can get you going on that with a great price shipping is only 4.95

The shift actuator in the gearcase is bad.
Replace the transmission.

I had this same problem with our GE top load washer.  I just needed to pull harder.  (Note: The agitator is held in place by about a dozen L-shaped clips in a ring around the agitator's base that will release more as you pull harder on the agitator.)  Everything from the base below the large fins on up comes out together.  Grab the shaft above the fins and pull slowly and hard. I had to take the entire tub out, lay it on the porch, put my feet inside of it, and pull the agitator assembly out.  I wasn't able to pull it out while it was still in the washer.  BE CAREFUL! DON'T **** IT OUT; that might injure your back; just pull out slowly and as hard as you can without hurting yourself.  I was able to get it out successfully, but I am currently stuck at removing the bell below the agitator.  Good luck!
