In the pan on the bottom of the valve body there is a few white wires and one black that connects to a switch at the front of the trans just in front of the TV hookup. This switch has 2 wires coming from it one red and one black. Trans had a rebuild.I dont know what the switch is called but the wires have twist locks on them and I cant remember but I think it was black to black and red to white???????? does it really matter there? Thanks for any help. I dont want to put fluid back in till I find out for sure.
