Shifting late from 1st to second?
Lately it's been shifting late and today it wouldn't shift out of first. I shut of the truck and restarted it and it will be fine and shift normally only does it from 1st to second and I have no check engine codes and oil level is fine. Tranny isn't slipping. What do u guys think it could be?
