Another Update
A few days ago I reported that, in zero degree F weather, the "new" tranny slipped again. Today, in 20 F weather it did not, but I introduced a new parameter (sorry). Basically, we live on a hill, so when I back out and then place in Drive, I have been on an incline (i.e. for all previous slip-related posts I have provided). Today I simply backed straight out, stopped, placed in Drive and drove back into my driveway (no incline). No slip today, when doing this.
So, I ask: Does the incline/hill exacerbate the slippage problem, or would such a manuever in the AM without warmup pretty much make ANY automatic car hesitate or slip?
Yes, I will test the tranny again, in this more moderate weather, going up the incline instead of on level ground as I did this AM.
