Maytag Washer won't spin

Model Number:
Brand: Brand
Age: Less than 1 year

Model Number: MVWC565FW0
Brand: Maytag
Age: 6-10 years

Will agitate and drain. Starts to spin and then "cycles" out and moves on to next cycle. Basket will free spin for 30ish seconds after spin cycle starts. Basket will free spin by hand with no tension or noise.
Only error Code is F0 E5 which doesn't make sense with issues.
I have removed the tub and parts on the bottom of the washer including gear box. Gear box had some rust and looked like excessive wear on teeth on end of shaft (see attached pic). I replaced the gear box and shaft, put the washer back together and....................... still having same issues. No other visible wear and tear on other parts/splines, etc.

Attachment 864

Here's a video with sounds of what washer is doing at beginning of spin cycle.
Any thoughts/help would be appreciated.
