I will take this to heart and do as much quick stop and go as I can.
The transmission started shifting really well, with the shift points almost exactly where my transmission used to be. Until the lack of engagement this morning I was thinking that it was breaking in really well. The transmission did this under identical conditions both times, this morning. Coming to a stop, transmission doesn't feel like it shifted fully into first, then trying to start rolling forward, engine revs up but truck doesn't want to catch. Give it more throttle, then engages.
