I had my car serviced recently and my mechanic informed me of the condition of the sub frame. Its rotted out pretty bad. Im not sure if its gotten worse since the recall work was done. He suggests replacing the sub frame. Is this an expensive job and do I need to replace it considering the recall work was done.

It vibrates worse when its cold and in drive . But not in neutral and now its making transmission slip sometimes. Could it be timing belt tensioner?
