Transmission Temperature Gauge for HD GM Trucks

If you’re towing heavy, running hard, or simply want to protect your investment, keeping an eye on transmission temperature is a must—and the AutoMeter Factory Match Transmission Temperature Gauge is built to do exactly that. Designed specifically for 2001–2007 Chevy Silverado and GMC Sierra 2500HD/3500HD trucks with the LB7, LLY, or LBZ Duramax, this gauge delivers accurate, real-time temperature readings in a clean, OEM-style package. Transmission fluid temp is one of the most critical factors in transmission health. Too hot for too long, and you're looking at premature wear or full-on failure. This gauge lets you monitor temps from 100 to 250°F, giving you the info you need to downshift, ease off the throttle, or simply stay in the safe zone when towing up grades or crawling through traffic on a hot day.

High-Quality Construction & Design

The face of the gauge features factory-matched LED backlighting that blends seamlessly with your stock dash. It looks like it belongs there—no mismatched colors or aftermarket flashiness. Behind the scenes, AutoMeter’s air-core electric movement delivers fast, consistent readings without pulling hazardous fluid into the cab. It comes with everything you need to get started, including a 1/8” NPT temp sender, 3/8” and 1/2” adapters, and full mounting hardware. You can install the sender in the transmission pan, housing, or even in a cooler line with an optional manifold, depending on your setup and goals.
