Howdy new guy here, well I guess as the title says both of my temperature gauges are not working. I replaced the sensor in the trans, and on the motor aswell. But I get no reading. So then I put the stock gauge cluster in and nothing yet again. Any help is appreciated thanks guys.

The 2001-02 trucks weren't known for cluster stepper motor failures, but a cluster problem is a possibility. I'd get a scan tool on it and see if the ECU and TCM are reading the temperature correctly internally. If so, the dash is suspect. If not, the sensors/wiring is suspect.

Im thinking its wiring just a guess, because i put my original cluster in it and that has only 10k on it. And replaced both of my sensors and still nothing.
