Some colder nights this week, so I'll get to test to see if I get the TPF message with the new battery.

Yeah, sorry - I know you have a 4.4 - my comment was directed at
ad01, who also has an M57TU diesel.
I doubt this has anything to do with your MAF (Mass Air Flow) sensor. While it is known that MAF sensor issues can cause a change in trans shift behaviour (by design) I don't think it's common for this to be temperature related and certainly not to the point where a fail-safe condition is set.
You also specifically mention seeing low voltages from time to time, something that IS known to cause a fail-safe condition. I work on the principal that if you smell smoke, look for a fire (there are no coincidences...).
