Hi.
Has anyone expierenced this problem or may help identify what the problem could be?
The shudder only happens when I am on a very slight incline and only when I have gently increased the speed to 55 & 56mph. if I set the cruise control at 56mph but on a flat or downhill road, there is no shudder, only going uphill.
The shudder is less at 55 but does not happen at 57.
It feels like when you need your wheels balanced, its that type of shuddering but not as savage.
Any thoughts & comments appreciated.

if ur car is still under warant take it to vauxhall or dnt drive at those speeds lol.
i would guess if it is only at that speed it could be gear box??
only a guess tho

I did have a shudder which would occasionally begin just below 60mph and last several minutes. It was more engine related though as the rpm would bounce up and down and the only way of overcoming it was to accelerate over 3000 rpm or change down. Strange enough it hasn't happened for the last 4 months or so, might have been a sensor or computer glitch but no error codes came up. If yours is the wheel balancing you would feel it in the steering regardless of whether you dip the clutch or not.
