Update - sort of.
Dealership has had the truck since Saturday. The thinking that the longer it sat until Monday would provide evidence of a weak start. Anyway, they called and said it started just fine. I asked if they load tested the batteries - no. They also said the transmission issue of a hard shift into 3rd could not be replicated. So they said they would keep it an extra day to load test the batts and investigate the trans issue further. They also said they have had no examples of issues with the transmissions. A little contradictory to what I am reading on line.
Curious what this "diagnostic test" will cost me.
More to come today. Or not. LOL
