Hi Staggers, No shudder on gear change and it changes very smooth, the mechanic said the trans was fine and just needed an engine mount changing, which has sort of helped, it happens mostly in 5th & 6th with gradual acceleration and more so on a bend with an incline, Which i have a few in Southern Tassie, lol, but if you drive it with more revs, no vibration at all.
I will have a look at the prop shaft and the bearing mount in the center support It's only done 125k so i thought it would be all good but i will check,
