I just finished my swap and took it for atest spin. When the power train was in the GT it ran fine. I left the motor and tranny together and took it out in one piece. Now i go down the road and after about 1 tenth of a mile I get this howling (LOUD) from the transmission tunnel area. I know since it is in that area it cud be anything from the trans to the rear end since the sound just bounces back and forth in there. I did a search and nothing matches. This is the same setup as in the GT, even the rear end is the same and i matched the drive shaft up as it was in the GT. Out of ideas here. PLease help guys!!!
