Product review (5 stars): Genuine GE Mode Shifter Assembly Cheap!
I bought this mode shifter assembly to repair my 7-year-old GE Profile washing machine.  The part  was a genuine GE replacement part in the original GE packaging.  The cost was substantially lower than my local appliance parts store and the cheapest I could find on the Internet.  I saved at least $50 by ordering this part online from Amazon.

The mode shifter is an expensive part that requires nearly complete washer disassembly to replace.  If you are going to bother replacing the mode shifter, you should consider replacing all the parts along the drive train that might be worn out or corroded.  I was able to order the tub nut, split ring, and drive belt on Amazon.  A new tub seal is included with the mode shifter assembly (although this is not mentioned in the description).

There are several YouTube videos that clearly demonstrate how to disassemble and replace the mode shifter assembly.  It took me about 4 hours to do the repair, but I was stopping regularly to take pictures and videos to help me with the re-assembly.  None of the repair steps are really advanced, you just need to be methodical to not forget anything.

The one thing I recommend highly is that you buy the TB123A spanner wrench to help remove the tub nut.  This was a $12 part on Amazon, and it helps you cleanly remove the nut that holds the inner tub to the mode shifter assembly.  I used penetrating oil on the threads, and with a couple of very hard whacks on the spanner wrench, my hub nut was loose in about 1 minute.  The TB123A wrench so cleanly removed the hub nut, it allowed me to re-use the original nut and save $8 on a replacement.  This was totally worth the cost of the wrench.

I was skeptical that I could buy appliance parts on Amazon, but this turned out to be a great experience.  I got everything I needed to fix my washer, and saved at least $300 on my repair.  Thank you Amazon and QuickShipParts.
