How about someone who was recently turned into a Cybertronian and Team Prime tended to and comforted them? They have a lot of adjusting to do! 👀
TW: A bit of implied disassociation because, holy shit, suddenly you're a giant metal robot and that's kinda hard to wrap your newly non-organic brain around.
((Knock Out is here because there is not enough Autobot!Knock Out and I love him.))
Team Prime comforting Reader, who just got turned into a Cybertronian, would include...
Optimus reassures you from the first moment that you have a safe home with Team Prime, should you choose to stay with them. Of course, you do. He makes sure you have the time and space to adjust and be comfortable with your new body before jumping into anything. He's just there if you need him, which some days is more helpful than everyone's else's efforts to offer unsolicited advice right off the bat.
Bumblebee helps you adjust to having wheels by challenging you to races that double as training whenever possible. He is almost certainly going easy on you, but nobody ever tells you as much.
Bulkhead is the first to realize that maybe you just really need a damn hug right now, if only because he's not very good with words. He hugs you and reassured you that it will be okay, and you're amazed how warm and fuzzy you feel afterwards, even though you're fairly sure your new body doesn't actually feel such minute temperature changes.
Ratchet tries to be "comforting" by explaining how your new body works... in detail that goes way, WAY over your head. But eventually, you get him talking about Cybertron's history and culture, and realize that your two species aren't all that different after all, which helps more than an anatomy lesson ever could.
Smokescreen is quick to remind you that you don't have to go back to your boring human school/job/house/whatever. Depending on how much you liked/disliked your old life, this is either incredibly helpful or incredibly irritating. If you get upset with him though, he's quick to apologize, and it's hard not to be comforted by that well-meaning smile and a servo patting your shoulder.
Arcee might somehow be even more protective of you than she is of the humans - she knows what happens when bots overestimate how much they can handle, and she figures that's really easy to do when you go from being a tiny, fragile human to a giant robot. Sometimes it's hard to hear her remind you that you're still mortal, but she means well. "Okay Mom, I get it."
Wheeljack, like Bulkhead, isn't very good with words, but he's also not very good with affection. What he can do, however, is listen. He's there the first time you get frustrated with the rest of the Team - not because they truly did anything wrong, but because being cramped into a tiny base with people you've just met will irritate anyone - and he never breathes a word of what you vented to the others. The Wreckers had their spats too - he knows you'll all be cool at the end of the day.
Oh Primus help Ultra Magnus he doesn't have a comforting servo in his body, but at least he's honest about that. In fact, he's the best bot to go to when you're ready to have things less sugarcoated.
Knock Out doesn't understand what the fuss is about - why would anyone ever want to be a squishy, gross organic when they could be Cybertronian? Humans couldn't turn into cars, for one, and couldn't be polished. He gives you a fresh coat of paint and polish and tells you how much better you look now - it does help, in a way. Being able to pick out new paint makes you feel a little more like your new body is really your body.
But honestly? Your biggest comfort might just be Jack, Miko, and Raf, if only because they will remind you any time you so much as frown just how cool being a giant robot is. And then you remember, yeah, it is pretty cool, actually.
