Unplug the harness from the trans it should default to third gear and you should only be able to select 2-3 manually that will tell if the trans is the issue

ok guys i used hptuners and it shifts into 3rd and 4th fine... i think my problem... i have no speedo which mean i think my tranny doesnt shift because it doesnt know what speed the jeep is at
... what happen if i set all numbers in shift to "0", will it shift using tps only?
