The best authority on this site to comment on your slippage on a hill is "Ross". But pending his comment, might I suggest it might be premature kickdown due to improperly adjusted throttle pressure linkage (very sensitive on this transmission). And perhaps some pressure tests are suggested. See the service manual, available on this site or hardcopy reprint from any of the major Packard vendors.
