I installed an Autometer electronic trans temp gauge with my new transmission, but I've had some problems getting a reading. I think it's a ground issue, but so far nothing I've tried is working. The temperature sender is installed in a brass T-fitting, in the flexible line I ran into the radiator. The T and the hose barbs are not grounded, and are suspended by the rubber hose. The instructions call for running a ground wire if the sender is not threaded directly into the tranny pan. I originally ran the ground to the fuse box area, and had no reading. I then tried to ground the T with the sending unit to the frame by running a wire. Then I ran the ground wire to the T, and grounded the T to the frame. Still nothing <img src="/forums/images/graemlins/confused.gif" alt="" />

Another issue I'm having is exactly how to ground the T, and the sender. Just to try and get some reading, I stripped a few inches of wire, and wrapped it around the T, with the other end grounded on a bolt. It's just a standard plumbing fitting, but I feel like I'm missing a simple solution here.

I did use teflon tape on the sending unit, but only one wrap. I talked to Autometer tech support, and they said it usually gets cut by the threads, and is not a problem. They also said it sounded like a ground problem.

Any suggestions?
