GlowShift’s Black 7 Color Series Transmission Temperature Gauge is ideal for any vehicle with an automatic transmission, especially diesel trucks that are towing heavy loads. The gauge allows you to easily monitor your transmission temperature from 80 degrees to 260 degrees Fahrenheit. You’ll also have the classic look of an analog gauge with an illuminated red needle that sweeps 270 degrees and choice of a blue, green, yellow, purple, red, teal or white LED display on a Black gauge face.
