    I have no idea whats the reason it works when it wants to. Every now and then it will flicker on and then nothing. I am wondering if the sender has crapped out.

    The gauge has been wired from the battery with a relay and an in-line fuse. It also has a ground routed to the body ground near the battery. I have a routed all the wiring away from heat as much as possible and all of the connectors have been sealed from moisture as much as possible. All of the wires have been checked for continuity and all check out.

    I'm stumped.

    Its an autometer Z trans temp gauge. The sensor/sending unit is mounted in a block of aluminum and clamped to the line. The aluminum acts like heat sink, its off the actual ATF temp by only 5 degrees. The block is still clamped tight to the line.

    make sure that you put the circle connector in the right place on the temp probe, you need to have the grounf touching the bottom part of the sensor for it to work correctly.

    Explain more if you can a picture would help. As far as I have read the only ground is from the gauge to a good ground source according to Autometer.

    Sending units often require a good local ground too.

    That must be it. Is there any way to set up a ground for the sender unit since I don't have a good area for a ground.

    If the sending unit is metal and is clamped in an aluminum block, then ground the aluminum block. It doesn't have to be a big ground wire--small automotive wire will do just fine.

    Set the ground wire up and ran an easy test drive down the road the temp. averaged 180*F. I had it peak at 195*F for a little when I passed someone on the road. It may be time for a cooler.
