Hi I have a problem when cruise is on - UZZ30. It seems to maintain around the correct speed but it jerks the car intermittently as if it is not adjusting the speed smoothly.
Seems to only do it at 90kph and above I've tried it at 60,70,80kph and works ok as soon as I go above ninety it will start jerking within a minute or 2.
My thoughts were VSS faulty But I'm hoping someone else may have seen the problem before.

next time it plays up, drive at a constant speed with cruise control off. Look at speedo readout. Is it constant or is it fluctuating? If fluctuating, then it is your speedo sender on the rear of the trans that is faulty. And this in turn causes the cruise to be faulty.
