Product review (5 stars): everything seems to still be working great.
The large plastic gear was stripped out in my washing machine's transmission.  This kit fixed my problem, and I didn't have to pay $80+ for the kit that includes the metal gear that didn't need replacing.  As long as I had the transmission open, I replaced everything that was in the kit.  After 10+ loads of laundry, everything seems to still be working great.
