Default Help please

First hello all I just bought a 08 with new trans and 2 yr old engine for .$450. Issue 1 will not shift from second to third. It is not pushing Any trans related codes goes into reverse perfect an shifts smoothly into second then the rpm rise as normal just until it should shift and it feels like it pops out but it dosant I am leaning towards either shift solinids or tcm program any advise would be great an second found a connector above inner fender well drivers side female black 2inch long almost round a fin on each of the corners on bottom t's a 6 pin connector but 5 are wired black green red top brown white on bottom looks like a white body clip it slides in to with 2 male ends .
