You are going to have to post in more detail to get some help.

The details are that it shifts smoother and all the shift points are different. Its shifting before it ussauly does like it hits 3rd at 24-25 then overdrive at 35. Trust me these are different shift points then before. If this help i had both batteries taken out to get new lights in and now i have np low beams and it is acting weird with thr shift points.
