Ah, sorry,
There is a reason people say, " Don't make assumptions"! haha.
If you have the model, just make a note of the animation frames and as you said, you replace the numbers in the fpe for your own frame sets.
So, for example,
The crouch could be 3100,3120, whereas yours is 210,230, just replace the numbers. If you are using the stock AI lua script, they will read the crouch animation frames when the model is supposed to crouch.
Either that, or, you will have to edit the AI lua to meet your needs. If it comes to scripting, unfortunately, that's where my knowledge ends! I can't code.
If you first, try to change the animation values in the fpe and see how you get on. If that doesn't work or you are stuck, come back here and I am sure someone more skilled with scripts will pop in and offer a hand.
Cheers
Jay.
PS, Transformers are awesome! I would love to see some pictures of your models!
