Start a new thread when you are done with the AutoRx. Being 3 quarts low in the tranny is bad because that level introduces air into the pump. Which is the root cause of your shifting and stalling. But there are an additional 5 quarts or so left to lubricate things, so you might be alright.
The lifter noise is no big deal if it goes away as soon as the engine warms up. Use regular oil with the AutoRx, and then switch to synthetic after the AutoRx procedure.
