Yes, you definitely need a schematic for a 4T60 transmission, showing the harness going in.....

The problem could be the harness to the tranny(broken or shorted wire), or the problem could be inside the tranny(second gear switch or the harness inside the tranny to the switch), or the ECM.....


Doing your electrical tests will determine which is at fault.....
