4 speed to 4 speed od clutch chatter
It's not from the different 1st ratio. Sounds to me like a clutch adjustment or alignment issue. The OD bell may not be aligned properly. They're also different enough that the clutch adjustment may need to be altered. The clutch fork is also a little different from the standard A33 to the A33OD, the pivot is different, etc. Not much, but again if you're using the 833 parts with the 833OD bell you may have some adjustment issues. Also, did you change the yoke? Some of the 833OD's use a different rear yoke than the 833. If you changed the yoke you may need to rebalance the driveshaft.
