Yeah ATF is fresh with only ~2k on it or so. Still red and smelly.
This is definitely new. Started on some easy trail/forest service road driving this weekend. First instance was at the bottom of a small, mildly steep hill we had stopped at the bottom of to look around. Just wouldn’t go up in high. Tried to replicate it a few different times and in different ways and it’s consistent.
Definitely noted on the reverse testing, although I would think being able to back up a hill in high should be fine?
