Ok, so I installed a new trans temp gauge after I installed the new trans and I can't tell whether it's workin or not. It is an eletrical gauge. WHen you hit the key, the needle move up maybe half an inch or so, so I believe the gauge is wired right, but I have heard that some go to full and then back down. IT has good power when the key is turned on, and good ground, but I have no idea how to test if the sender is working. I have yet to see this thing move, and I am beginning to wonder if I have done something wrong, ANY HELP ??????
