Product review (5 stars): OEM coupler
Needed for GE Profile Hydrowave washer.
I ordered this part because I found it cracked at the base when I was taking the tub out to replace a defective mode shifter (WH38X10017).  If you go to replace the mode shifter, check this coupler and replace at the same time if cracked.  I also replaced the drive belt that showed significant stretch compared to the new one.
