Product details
Transmission fluid temperature is the single biggest contributing factor to the lifespan of your automatic transmission. Having an accurate, realtime measurement allows you to know when to downshift or when to take your foot out of it. 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. GAUGE, TRANS. TEMP, 2 1/16", 100-260ºF, DIGITAL STEPPER MOTOR, CHEVY RED BOWTIE, BLACK GAGE, TRANS.
