If I may give my worth. You said on your prior post back in 2009 that when you had the car up on the lift you said and I quote (i noticed the tranny mount looked kinda sideways also) Why would a trans mount go sideways? Is everything from the rearend thru the drive shaft thru trans. up to the engine inline correctly. Or is it possibly pulling to one side so much that the whole assembly is cocked which would cause your mount to go sideways or vibration. Was this car ever wrecked in the rear? Hey, I'm just asking! I know that could be a stupid question but it seems like he has tried everything unless your machine shop or anyone that has done work on your engine/trans is lying about performing the balancing that is required.
