1.9 CDTi (Auto) Gearbox judder and fuel problem!

[Vectra Singh]

Hi folks,

I've noticed when i'm driving my car 40mph the auto gearbox changes it to 4th gear and then i get a juddering!

Also BC1 timer show's i'm getting 27.9MPG and that's through normal driving without kickdown!

What could be wrong?
