This 2 1/16 inch (52mm) transmission temperature gauge beats the competition with features like a peak recall function, programmable high and low warning functions, stepper motor technology, 10 color through dial LED lighting, as well as a self-calibration mode at startup, as well as a low profile tinted lens. The adjustable high and low warning functions will alert you visually or with an optional audible tone, and the peak recall feature gives you an instant vehicle feedback. The included stepper motor technology ensures all needle movement is remarkably smooth and all gauge readings are incredibly accurate. GlowShift’s 10 color through dial lighting allows you match your factory gauges or add a unique look to the interior of your vehicle, and with the color recall feature, you won’t have to worry about resetting the gauge to your preferred color every time you turn your vehicle on. This transmission temperature gauge also dims 30% when connected to your factory headlight switch, making it much easier to read when driving at night. GlowShift’s Elite 10 Color Series Transmission Temperature Gauge’s sleek 1/8th NPT electronic temperature sensor can be installed by replacing your stock sensor or by installing it directly to your transmission’s test port. All of the included sensor and power wires are completely plug and play, and securely snap into the back of the gauge with modular connectors. This transmission temperature gauge is powered by 12 volts and will let you power an additional three Elite 10 gauges with the daisy chain feature.
