Just to clarify the sound, it’s a knock/vibration – knock over bumps vibration on acceleration only. In manual gears it does the same as it does in auto. If I hold it in second gear and Accellerate I still get the vibration removing, in my mind, any gearbox related issues.
I’ve ordered a new engine mount regardless as it does look knackered and I will change and see whether this fixes the problem. I’m hopeful this will be the case

Are you sure it isn't the front mount as the rubber bush perishes and then start to knock on acceleration/deceleration etc and its the easiest to change or perhaps the wishbones bolts are loose and need nipping up?
