I disagree. Transformers' sexual dimorphism doesn't make sense in-universe, but in the absence of primary sexual characteristics I'd still be fine with referring to sexless non-humans as "he" or "she" and not "they" or "it" - even for someone like a Bolo, who is just a sapient ultraheavy tank and has no secondary sexual characteristics either.
