I didn't find any topics on this subject on the forum so I decided to post some interesting information that I found on wiki. Of course the info is not 100% confirmed but is reliable.

"Pre-shoots began on April 7, 2010 in Indiana, which will portray Ukraine and Los Angeles. Filming began on May 18. First six weeks are in Los Angeles. Filming locations of LA are including Sherman Oaks, Fourth Avenue and 5. Main. Next four weeks take place to Chicago. Filming locations of Chicago are including LaSalle Street, Michigan Avenue, Bacino's of Lincoln Park at 2204 North Lincoln Avenue and around the "Sears Tower". The Michigan Ave scene is filled with crashing and explosions. In early August filming is going to Washington, D.C. and Florida, just before the launch of Space Shuttle mission STS-133. The Washington filming is going to be on the National Mall. Michael Bay says 'We will have a car race on the National Mall. There are two announced locations, the Milwaukee Art Museum and an old factory location of Tower Automotive, currently under redevelopment as mixed use including City of Milwaukee equipment yard, where filming will take place after Chicago. In August they will be filming in Detroit."

We all know that part of the plot of the movie will be concentrated on the space race between USA and Russia and the fact that they are shooting at the time when the real shuttle mission STS-133 launches is magnificent. They will save some money for CG there.
Also the news for the car race at the National mall is new to me and maybe the Nascar cars will appear there for the first time and then they will be chased by the autobots off circuit on the city streets.
