I recently had a 4l60e to 4l80e swap around town it shifts up and down just fine sometimes 1 to 2 is a lil hard. But when I get into higher speeds it'll shift fine till I decrease speed then it'll shift down to third and won't shift back up till you practically red line it. And also I set the cruise sometimes it'll down shift. Idk helllllpppppp????
