Product Details

The AutoMeter 3857 GS Series Transmission Temperature Gauge provides the precise, real-time monitoring essential for protecting your automatic transmission. Transmission fluid temperature is the single biggest factor affecting transmission lifespan, and this gauge delivers data acquisition-grade accuracy to help you make critical decisions whether towing, racing, or running high-performance builds.

Digital Stepper Motor Technology:

  • Race-proven digital stepper motor movement provides unmatched accuracy and smooth needle motion
  • Self-calibration sequence during power-up ensures consistent precision
  • Monitors temperatures from 100-260°F with exceptional resolution
  • Electric operation keeps hazardous fluids safely outside the cabin

GS Series Styling:

  • Modern 2-1/16" gauge with futuristic design aesthetic
  • Translucent white dial with black markings for high contrast
  • Fluorescent red pointer for quick reference
  • Green LED through-the-dial lighting provides excellent nighttime visibility
  • Bright anodized Super Bezel with flat, clear lens

Complete Installation Kit Includes:

  • Data acquisition-grade 1/8" NPT temperature sender with superior accuracy and durability
  • 3/8" and 1/2" NPT adapters for flexible installation options
  • Plug-in wiring harness for simplified installation
  • Mounting hardware and detailed instructions
  • 12 and 16 volt compatible for versatile applications
