Does it whine when you let off at speed and put it in neutral with the clutch out? If so then it might be the rear output shaft bearing, if not it probably is in the rear end scope
If it didn't make any noise before installing THIS tranny then it has to be in the trans. shruggy
Please let us know what you find and do thumbs
