I don't believe so.
My Dart is still at the painters for final cut and polish - should be home in the garage sometime in August (the painter's wife is ready to "pop" with their first child so, understandably, there might be a delay).
The engine is still on the stand and the trans is sitting on the garage floor so hasn't been behind a running engine yet. It was mocked in place with the engine so the trans mount crossmember could be installed and all went well without any issues.
