Gearbox ,vibration

Start again in the middle of Refurbishing a 05 plate range rover Overfinch 580s one with the bored out 4.4 BMW engine in it I have a problem with a vibration at all speeds but more noticeable at 50mph fitted a new torque converter about 6 weeks ago problem vibration nearly when but was still there any ideas am thinking in may need a rebuild on the gearbox ;( the people that fitted the torque converter landrover themselves changes the old but not the filter ? Could this be the Corporate or am a been a tad Optimistic ;0)

Slightly better was more thinking intro as in who and what in here and then leave the problem thread but close enough!
If you put up your location someone might be close enough to help
