JRP GearX 52mm Digital Transmission Temp Gauge
With the growing popularity of our gauge systems among the 4x4 diesel community, we continue to innovate and create products that matter most to off-road drivers. One of the most requested additions to our multi-gauge systems was a dedicated transmission temperature gauge—and the feedback has been overwhelmingly positive.
When the GearX range first launched, we only offered an oil temp gauge, which some customers used for transmissions. But because the demand was so strong, we developed a purpose-built auto transmission temp gauge designed specifically to monitor gearbox fluid temperatures in real-world towing and off-road conditions.
Why Transmission Temperature Monitoring Matters
Protecting your automatic transmission is crucial, especially for vehicles that tow heavy loads or tackle tough off-road terrain. Fluid that runs too hot can quickly damage your transmission, and repairs are expensive. With a dedicated trans temp gauge, you can:
-
See real-time transmission fluid temps (know what’s “normal” for your vehicle).
-
Catch rising temps early and back off before damage occurs.
-
Extend the life of your transmission and fluid.
-
Set custom warnings for peace of mind under load.
Built for 4x4 & Diesel Owners
Our 52mm GearX Transmission Temp Gauge is the perfect companion to gauges like Boost, EGT, and Water Temp. Whether you prefer a pillar-mounted single gauge or want to add it to a multi-gauge setup, GearX gives you the flexibility to monitor all your vehicle’s vitals.
The GearX lineup has grown far beyond the original release, now offering dedicated diesel boost gauges, intake air temp gauges, and more—all designed with input from our loyal 4x4 customer base.
