140-280 Trans Temp Gauge

The AUTOMETER 140-280 Trans Temp Gauge is a critical monitoring tool for any driver concerned with the longevity and health of their vehicle's automatic transmission system. Excessive heat is the leading cause of transmission failure, making a dedicated temperature monitor an essential upgrade for towing, hauling, or high-performance racing applications. By providing a clear window into the thermal state of the transmission fluid, this instrument allows you to manage loads and cooling cycles effectively. It serves as an early warning system that can save thousands in repair costs by signaling when it is time to back off the throttle or improve cooling capacity.

This mechanical analog gauge features a high-visibility black face housed within a 2-5/8 inch diameter casing for professional-grade integration into any cockpit. The liquid-filled design is specifically chosen to dampen internal movement, protecting the delicate mechanism from the high-frequency vibrations common in heavy-duty diesel or racing environments. Utilizing a full-sweep needle movement, the gauge offers superior resolution and accuracy across the entire 140 to 280 degree Fahrenheit operating range. Because it is a mechanical unit, it operates via a physical temperature probe and capillary tube, ensuring reliable readings even in the event of an electrical system malfunction.

As part of the renowned Pro-Comp series, this unit is designed for enthusiasts who demand competition-level performance and rugged dependability from their instrumentation. The larger 2-5/8 inch format is ideal for mounting in custom dash panels or universal pods where quick, at-a-glance monitoring is required during intense driving. Compatibility extends to most automatic transmission systems where a temperature sensor port can be accessed or added to the transmission pan or fluid lines. Professional installation is recommended to ensure the mechanical capillary tubing is routed safely away from heat sources and moving parts to maintain system integrity.
