38 months to the date new batt/alternator.....
Pretty sure it would have been a Bosch Reman.
They are all *reman*, aka, OE vs OEM

Post#5 - the trans harness/wire/temp sensor was changed out many many moons ago. It's been fine since. Truck has been solid with the only ~change ~ was messing with bulbs this morning and coincidentally the trans safe.

Going to see how the battery looks on the MM after a sleep overnight.
