I used to use Valvoline oil change for my NY State inspections because they did no repairs. I heard them tell the owners of many cars that they used Dexron with an additive pack that made it compatible with their car. I would not go there for a trans fluid change.
When they started selling batteries they told me my battery was bad on my 2012 Camry when it was 4 years old, and again at 5,6,7 and 8 years old. I replaced it at 10 years old.
