Product Details

The AutoMeter Pro-Comp Mechanical Transmission Temperature Gauge delivers precise, real-time monitoring of transmission fluid temperature—the single biggest factor affecting automatic transmission lifespan. Whether towing heavy loads or running a built or boosted motor, this gauge provides critical data to help you know when to downshift or back off the throttle before damage occurs.

Key Features:

  • 2-5/8" diameter gauge with 140-280°F temperature range
  • Liquid-filled mechanical design for superior shock and vibration resistance
  • Liquid-dampened movement ensures smooth pointer operation and extended service life
  • No electrical connection required—purely mechanical operation compatible with any vehicle
  • Includes 8-foot capillary tube with 1/2" NPT adapter for transmission pan installation
  • Traditional incandescent lighting illuminates around dial perimeter
  • Fluorescent red pointer for easy reading
  • Brushed aluminum Super Bezel with flat clear lens and black dial face

What's Included:

  • Transmission temperature gauge with 8' capillary tube
  • 1/2" NPT mounting adapter
  • Bulb and socket assembly with red and green bulb covers
  • Complete mounting hardware and detailed installation instructions

This mechanical gauge provides race-proven accuracy without the complexity of electrical wiring, making it ideal for both street and race applications. The liquid-filled design protects internal components in harsh environments, while the 2-7/8" outer bezel diameter fits standard gauge cups.
