Hi,
I have just finished replacing the DG gearbox with a 4 speed o/d
manual on a S type.The back wheels are off the ground and there seems to be a slight shudder while going thru the gears but no shudder when accelerating in neutral.The tailshaft has been reduced by 45 mm.I used the original DG gearbox mount.Any ideas out there? I am thinking gearbox to diff alignment or tailshaft out of balance??

in the S type, the mount for the manual transmission is different than for the automatic.

what year is your S type ?

It's all good,the vibration was a "Good Vibration" from too much champagne to celebrate.
The S is 1966. I have used the original Auto trans bracket,it bolted straight up to the existing holes just had to remove a bit of metal, in the centre, the uni joint was scraping.I have also made an alternator/power steer pump($150) mod and its running perfectly.
I have noticed that there is a difference between what you should use and what you can use.
