Hi. This is my first time posting on here. I have a Model WBXR1060T2WW G.E. washing machine. The agitator has stopped agitating during the wash cycle. It still spins with the tub on the spin cycle. I pulled out the agitator and removed the agitator coupler. The splines in coupler are gone so I know that's the reason it is not agitating. I can''t tell if the splines on my transmission shaft are worn away or not. I am trying to clean it enough to tell. What is the best way to clean off transmission shaft to see if splines are worn out without ruining splines?

Thanks Fairbank. Wire brushed shaft and tried to clean out splines with small flat screwdriver. This machine is 17 years old and the splines are severely corroded, some even completely gone. Cleaned as best I could and still had to force new coupler down onto them. I think it is time for a new washer since a new transmission costs around $250! But in the meantime it is back to working, for how long who knows?
