I recently had some work done on the transmission. I sent a post in a cople of weeks ago about that. Now, all you Taurus experts, here's an interesting one. By removing and re-installing the transmission, could that could cause engine noise to reach the car's cabin. I'm pretty sure the exhaust system is ok as the car seems as quiet as always. But from inside the car it seems much more noisy. The Taurus always was niece and quiet but now when I start it it's loud in there!
