    After fixing whatever was wrong with my truck last week (apparently battery terminals). I’ve noticed that when driving fast from a red light the rpms go to like 4 to 4.5k before shifting hard into second and third. Now I drive it normally it shifts like butter in every gear. Before I changed battery terminals I did have an o2 sensor code thrown but the new terminals made it go awAy. Any suggestions? (2012 tundra platinum crew Max)

    Since you disconnected the battery, the ECM might need a little time to re-learn the way you drive. I would drive it normally for a bit, and see if it goes back to normal.
