Do you think the current research into gender transition doesn't account for autism as a variable? There is a medical consensus for the current treatment for a reason. For a person to properly transition, they will have undergone years of psychology assessment and so on, seems to me that an autism diagnosis would immediately follow. Is there any evidence of correlation between trans individuals and autism? (There may well be literature on it, I'm genuinely asking).

Also, if that were the case (autism misdiagnosed as gender dysphoria etc etc) you wouldn't have the robust literature with follow up surveys of individuals and how satisfied with their outcome they are. The outcomes of medical treatment of gender dysphoria are quite positive; if like you said, in the end they still don't know how they feel, these outcomes would be vastly different.

This is not so much an unpopular opinion on something which might be ambiguous or up for debate, it's an incorrect opinion which goes against evidence.
