Autometer GS 100-260 degree Electronic Trans Temperature Gauge

Whether you’re towing or simply trying to harness the power of a built or boosted motor, AutoMeter’s Digital Stepper Motor Trans Temp Gauge will give you the most accurate possible measurement for the exact temp of your trans fluid. AutoMeter’s most advanced 1/8” NPT temperature transducer is included as well as a direct plug in wiring harness for ease of installation. An optional trans cooler line manifold is available for another easy installation option.
