The manual shows it but the NEO is attached in a way in the render where the bolt holes in the NEO don’t line up with the gearbox. When the NEO is lined up, only two bolts actually will fit.
Also, I am not exactly sure how the motor pinions are supposed to stay on the gearbox:
All CIM-style motors are interchangeable. This includes CIM, Mini-CIM, NEO, and Falcon. Neo only need two screws.
The pinion gears will come with two retaining rings and a key to hold them on and transfer torque. The retaining rings go on either side of the gear. The key goes in the slot on the shaft.
You need to use the two bolts holes that are highlighted in blue. If you are buying CIM pinions from WCP or VEXpro they come with hardware to retain the gear.
