Hey all. When say sit on a 100 and i slightly let go of the pedal the whole car will shudder. I cant seem to work it out but i only seems to do it at around 100.What could it be. I was thinking it could be the gearbox but i dont no!!!

Wheel alignment, or at worst case it might be the bushes.
Take it and get a wheel alignment done, and see what happens from there.
Also, if you have retreads or poor tyres, occasionally these can become oval shaped, so this might make the car unstable.
I wouldn't be be concerned about the gearbox otherwise you would be having troubles way before 100kmph.

check your tail shaft uni joints and center bearing.

I second xcop5l's suggestion..

Mite be a long shot......I hope you have the right wheel nuts? haha

not likely at that speed, but theres a possibility that its the converter slipping.
it makes a terrible shudder throughout the car and a slight noise.

well thnaks for all your thoughts i will have to have a look into them untill i can work out what it is. I had a thought of the wheel alignment. But thanks

i'm having same problem but seems to be at about 120 onwards to about 140 but i havn't noticed if it goes out of it after that speed if it does i would have to say uni's or center bearing?

Where do you drive at 120-140kph?

To make sure its not the trans just unplug the plug on the passenger side of the transmission it is the lockup. It wont do anything but maybe use a little more fuel on the freeway.

I HAVE A 98 VT SS MANUAL SEDAN AND HAD A NEW CLUTCH PUT IN THIS WEEK & EXTRACTORS FITTED, NOW WHEN ITS IN REVERSE IT SHUDDERS! SOMEONE SAID THEY EITHER HAVNT MACHINED THE FLYWHEEL OR THE FLYWHEEL HAS A FLAT/HIGH SPOT IN IT & THEN SOMEONE ELSE MENTIONED ENGINE MOUNTS. SURELY WHEN THEY DROVE IT OFF THE HOIST IN REVERSE THEY NOTICED IT?
