Vibration, gearbox , help,;(

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)

The main issue with the ZF box is the bearing between B & C clutches fails causing movement which wears out the O Ring sealing A & B clutches....this cause A clutch to slip causing a vibration.....the TQ then gives up as it is trying to limit slippage and the poor LUC fails in the TQ....

I would hazard a guess your A clutch is slipping.....

Hope the bill isn't to eye watering for you.....

Think I may cry when I pick it up worth it tho nothing is better when it works properly that is

On a good note tho everything is brand new now so it should be good for a few weeks now ;0)
