My understanding is that the motors themselves cannot be modified.
The transmissions are another matter.
The transmissions can be modified as desired. I think that this applies to the Drills, the Fisher Price transmissions, and the Globe transmissions.
What cannot be done is to modify the motors with worm gears to take power off 'upstream' of the worm gears (the seat motors, the window motors and the sliding door motors).
From conversations with FIRST, it seems that they are mostly trying to prevent teams from ruining motors that are difficult to replace. The transmissions on the drills, F-Ps & Globes are relatively easily removed, taken apart, & put back together. Once a team cracks open one of motors with the worm gears, the motors are more or less toast.
I don't have the actual chapter and verse of the rules that allow this but I am fairly sure that this is a correct interpretation.
