I can make an approximate guess, based on all the information given so far.
Megatron wants to find the Autobots but is too lazy to hunt them down himself, so he hires Shockwave's Predacons, probably bounty hunters, to do it for him.
Arcee, Bulkhead, Bumblebee, and Smokescreen are shipped off all across the U.S. When the reunite, Ratchet isn't with them. This is because he left Team Prime (he has no hope left), attended to a severely wounded Wheeljack and runs off with him. Together, Ratchet and Wheeljack find the Dinobot's leader, Grimlock, and the duo aid their beastly friend in finding the rest of his team here on Earth.
Meanwhile, Ultra Magnus (crashed on Earth while looking for the Dinobots) takes the four stranded Autobots (and their human friends) in as his own. When they learn of the Predacons hunting them, Magnus gives all the Autobots upgrades from his crashed ship so they can defend themselves.
And Optimus returns at the end to advertise his new toy.
