More details about the filming in Michigan, noting that three of the previous four have had some filming there - TF1, TF3, TF4.

“They have filmed several Transformers productions (at the Michigan Motion Picture Studios) in the past, and I expect they would utilize some of the same locations,” says Jenell Leonard, commissioner of the Michigan Film and Digital Media Office, formerly the Michigan Film Office. “However, all production locations are tentative and fluid.”
Leonard expects that production on Transformers 5 will start in the summer and will end in the fall. Transformers 5 will be the fourth film in the series shot in Michigan, joining the original 2007 film as well as Transformers: Dark of the Moon and last year’s Age of Extinction. In Age of Extinction, Paramount created a set in downtown Detroit on the site of the former Statler Hotel that was designed to look like Hong Kong.
