2-1/16" GM CAN-Bus Trans Temp Gauge | 140-300°F with Warning | OBDII ECU

The CAN-Bus GM Temperature Gauge reads temperature data directly from the ECU through the OBDII CAN network for a cleaner install with no external sensor required when supported. Built for 2008+ GM ECUs with CAN temperature output, it delivers real-time temperature monitoring with smooth, stable, and accurate needle movement, while a settable warning light adds a clear visual alert when temperatures move out of range. Slim housing, solid aluminum bezel, and spin-lock mount keep it built for long-term use. Made in the USA and backed for life.
