Just to explain what the adjustment does.
In first gear the forward clutch is on, to change to 2nd, the band is applied, no problem. To get 3rd, the band is released, and the high clutch is applied. If the band is too loose, the band will release before the high clutch locks-up. This causes the flar in the rpms till the clutch locks-up for 3rd.
If the adjustment is too tight, the band will be too slow to release, and will still be applied when the high clutch locks-up. This will cause the box to bind till the band does release.
The timing between the two actions, band off, high clutch on, is controlled by the one servo action. The same pressure releases the band and applies the clutch. This is why the amount the adjustment is backed off, sets the timing between the two actions. Too tight, it binds, too loose it flars.

Thanks Tom and Harvey,
My band definately needs tightening. Does anyone know why some specs call for two turns and SVX specs call for three turns?
Checked our 4.44 Outback trans from wrecker, it was exactly two turns.
I know what flar feels like, bind sounds worse!
