Elect. Trans Temp. Gauge

The AutoMeter Electronic Transmission Temperature Gauge (model 4457) is a precision instrument designed for serious builders and mechanics who demand real-time transmission fluid monitoring during high-performance driving, towing, or track use. Transmission temperature directly impacts fluid viscosity, shift quality, and component longevity—making accurate readouts essential for anyone running modified powertrains, heavy loads, or spirited driving.

This gauge provides the visibility needed to prevent thermal damage, optimize shift timing, and extend drivetrain lifespan in demanding conditions. AutoMeter's electronic design eliminates the lag and reliability issues of mechanical gauges, delivering instant sensor response to temperature fluctuations in the transmission pan or cooler line. The gauge uses a precision thermistor probe that communicates electronically with the dial head, ensuring accurate readings across the full operating range without mechanical friction or hysteresis.

Electronic transmission temperature gauges are less susceptible to vibration-induced needle flutter than mechanical alternatives, and they integrate cleanly with modern vehicle wiring while remaining fully serviceable. The compact design fits standard 2-1/16" gauge mounting locations, making installation straightforward in custom dash panels, center consoles, or pillar pods. This AutoMeter gauge is ideal for transmission builders, engine swap specialists, off-road enthusiasts, and anyone looking to enhance their vehicle's performance.
