Hi all. We have a '93 V6 5 speed with 160K miles (200K km) on it. Power train was juddering on takeoff so had it in to the dealer to replace the clutch. They machined the flywheel and changed the clutch parts. $1000 CDN later and it still judders. O2 sensor throwing codes now too. Could the judder be a problem with the pilot bearing, input shaft or input shaft bearings rather than the clutch? Worried that a gearbox rebuild might be the next bill. Car goes back next week.

The pilot bearing and throwout bearing both SHOULD have been replaced when the clutch was done.

Can't tell you much about the input shaft except that in all the time I've spend here (which is alot), I've never heard of it. Either way, the transmission will have to be dropped again.
