95 intrepid limp mode

my 95 intrepid is in limp mode. I have checked a few things and found there is no power coming off a light green wire at the trans controle module. That is the 12volt supply wire i checked this on a wiring diagram. Could this be a computer problem. I am able to apply voltage to this wire using a jumper from the battery and i can here the relay clicking on but still no shifting.
