BUT - they changed the design so a power switch previously separate from (to the left of) the circuit board is now a microswitch integrated on the board, leaving you with ONE LESS WIRE.
Attached is the fix diagram & directions for the new design.

Remover screws from top. Used snap ring pliers to remove snap ring replaced gear and reassemblied.

removed top housing, removed gear housing cover, removed all gears, cleaned out all grease, obtained gears and new housing cover, fit all gears in housing, filled with grease and put on housing cover.
Reassembled mixer.

The repair was easy, I only had to order new gear assembly parts and to replace the associated worn parts (shaft, pin, and gears).

I went to YouTube and there are several Mixer repair videos that go through step by step. Four ounces of food sate grease is also required as the grease must be changed. This appears to be a a common problem. One issue that I discovered is that the old planetary had an Oring in the shaft The replacement parts do not. They must have changed the design so please make sure that food safe grease is used.

Removed top cover of mixer which was very easy. Then marked the 4 wires so they could be plugged back to new switch correctly. Removed 2 attaching screws to remove switch and one squeeze connector. Installed new switch after plugging on 4 wires. Snapped squeeze connector in place. Reinstalled top cover.

Just followed the video.amazing!!got my kitchen aid back.

Skewer the screw in with my fingers,

Fast

Thank goodness for YouTube. Pretty much followed the process of taking it out. Was easy, but having a video made it a bit simpler.

First you need to remove the aluminum ring around the housing by using a Phillips screwdriver and removing one screw. You will then have 4 screws around the housing to remove. Once the screws are removed lift the housing and set aside. At the front of the machine there is a housing that encloses the gears. Remove the 4 screws, lift the housing and set aside. At this point you will see the gears and on the shaft there is a snap ring that needs to be removed. Once the snap ring is removed tap the shaft down and remove it from the bottom. To assemble insert the new planetary and reverse the steps to reassemble.

using Phillips screw driver, remove 5 screws - take off cowl (cover)l. remove 2 screws holding speed control assembly
unplug old speed control assembly (4 plugs) and plug in new speed control unit - reassemble cowl .

I followed the instructional video closely. My old circuit board was labeled and laid out slightly differently than the new one, so in addition to labeling the wires with "color" or "motor" label from the old board, I also made sure to label with more identifiers that were included on both boards such as "P1" or "P2". Once I labeled the wires with all the information, removal of the old board and installation of the new board was straightforward. This isn't the first repair I've made on my KitchenAid but it was by far the simplest.

Removed 2 screws holding the switch unplugged the one at a time.
opened the gear box cover 4 Philip screws, cleaned out the grease
removed the pinion gear, removed pin, removed the planet gear assembly replaced gears in reversed order greased it up put gear cover back on and tested worked great.
