Trans Gauge Help
Just installed a trans temp gauge, so I went out for a little test run to check that everything is working. The truck was sitting for about 3 hours while I was installing all the gauges, as soon as I started it up the trans gauge started to climb upto about 180. Within 5 minutes it was pegged out at 250.
The trans is running strong, no unusual noises, fluid has been changed 3 months ago, no codes, O/D light not blinking. I am lost as to what is causing this. The fluid doesn't smell burnt, I am hoping it is just a duff sender. Any help would be appreciated

Too busy installing the HPx line to check the trans temp. I'll go through the wiring again and check the ground. It is an Autometer trans temp, does anyone know what type of sender it is? ie Thermocouple, thermister, RTD. I used 16 gauge wire, I wonder if I should be using 18 gauge.

16 gauge wire should be more than enough. It really dosen't need to pass very much current in this application, but remember that they use 16 gauge in some homes for lighting and receptacles. It is capable of handling around 10 amps at 120 volts, way more than you would need for this. Also remember that the smaller the gauge, the bigger the wire. 16 gauge is bigger than 18! I'm with Cookie, either a bad sending unit or grond issue. Remember the gauge has to have a good ground, but so does the sending unit. If there is any break or weak link in the ground path between your sending unit and your gauge ground, that's most likely your problem.

Well I think I have sourced the problem. I checked the ground and everything seemed good, so I pulled the gauge out of the pod to check the wiring. Every time I moved the 12 volt supply lead, the needle would swing either to the low end or peg the gauge out. On the Autometer gauge, there are 3 terminals. One hot, a neutral and one for the sensor. But they are combine in a spade/post config. So really there are 6 terminals. The spade terminals contact the post and are held in place with small nuts and lock washers. Well the positive terminal didn't have the nut in place so I was getting a partial contact. Guess the way the wire sat in the pod, would cause the partial contact and give me a false reading. So everything seems good now. Thanks for the help
