A833 no shift

Wouldn't a dragging clutch cause all sorts of grinding noise when trying to shift ?

Not unless the brass is worn out, and you over-power it.

I currently am having an issue down shifting to 1st unless I am rolling.

This is caused by the input gear train failing to come into synchronization; usually because the clutch "is dragging". The most likely culprit is insufficient clutch departure; but other causes could be; a warped or fractured disc, BH misalignment, the input gear is stuck/sticking in the back of the crank, the mainshaft is is not rotating freely in the back of the input gear, or any gear is is binding on the mainshaft.
If you are downshifting under closed throttle, and the engine has returned to idle, you are asking the brass ring to speed the gear train up to driveshaft rpm. The brass ring can only do so much. The usual fix for this is to blip the throttle to get the rpm up closer to driveshaft rpm, then in a perfect world, the brass can do it's job.
