The GM CAN-Bus Transmission Temperature Gauge with Warning Light reads trans temp data directly from the vehicle’s ECU through the OBDII CAN-Bus network, giving you a clean 60–150°C metric temperature range without adding an external sender when supported by the ECU. Built for 2008 or newer U.S.A. GM vehicles, it is designed for cleaner wiring, faster setup, and reliable transmission temperature monitoring from the data your vehicle already provides. The integrated warning light adds a clear visual alert when transmission temperature reaches the set threshold, while a microprocessor-driven movement and high-torque stepper motor keep the pointer smooth, stable, and accurate. Finished with a slim case, spin-lock mounting, solid aluminum bezel, and weather-resistant build, it is made in the USA and backed for life.

Track-Tested. USA-Built. Backed for Life.

Key Features

Important OBD2 CAN-Bus Notes
  • Supported Data Required — vehicle must output CAN temperature data through the OBD2 port
  • Dedicated OBD2 Connection — no other devices can share the port
  • Data Only Through OBD2 — separate power and lighting wiring required
  • No Analog Input Support — not compatible with analog senders or raw signals
  • IPX6-Rated Protection — sealed against heavy spray; not for submersion
