New 1350 shaft,pinion flange ,th400 output shaft and balanced.Shimmed pinion up 2° very bad vibration that would begin at 110mph,no vibe on let off.Shimmed pinion down 2 no vib up to 135 but bad vibration off throttle.Put it back no shim no vib up to 135 ,bad vibe off throttle .I'm right back where I started trying to solve this issue.Shaft had to be balanced 2x to solve vibe at load up to 135.My output shaft bushing does have up and down movement and gear back lash seems excessive.
