3rd gear shift issue

Questions: what oil in trans?
how is the OD -3 downshift
how is the 2-1 downshift
did you align/index bellhousing to block

It's Sta-bil 75w90 or 80w90 GL4 I believe. Have the jug still can double check.
OD-3 downshift so far has been fine
2-1 is also fine as long as I'm coming to a stop (haven't tried it any other way)
Yes, I indexed the bell.with the offset dowels.
