The dealer claimed they had done everything before we bought it. We've only driven it about 3000 miles.
The fluid looks very clean. In fact it is hard to read on the stick (must be this new Dexron VI or whatever is more pale than the older ATF). I will press them about the fluid when I take it in.
This was a 4yo truck originally bought at that dealer and then traded in for a new 2020. We bought it in April 2020.
