I would hope that you looked on the transmission for the transmission connector? Anyway, it should be located on the top of the transmission. Just look for a large harness coming from that area and follow it. It may not connect directly to the case but have a connector 4-6 inches from the transmission. This is where you would separate the two. If the resistance seem questionable, don't jump to replacing the solenoids. Next, I would drop the pan and check the solenoids directly to make sure it isn't a problem in the harness. But if the values look good through the harness than you don't need to do this last step. Good luck! Send me an IM if you need any literature on the trans.
