AutoMeter - 2-1/16" Transmission Temperature Gauge 100-260F - 4957

Monitoring transmission fluid temperature is one of the most critical factors in protecting the lifespan and performance of your transmission. This AutoMeter 2-1/16″ gauge offers a range of 100-260 °F and uses a high-precision digital stepper motor movement for smooth, accurate needle response. It includes a data-acquisition grade 1/8″ NPT temperature transducer, a direct-plug wiring harness, and often adapter fittings for ease of installation. 

The kit is designed for high-performance or heavy-duty applications—whether you’re towing, performance-driving or simply want to monitor a built transmission under load. The full-sweep analog dial provides fast visual feedback, while the premium construction and included wiring make installation cleaner and more reliable.

Key Features

• 100-260 °F measurement range suited for automatic transmission fluid temperature monitoring. 

• 2-1/16″ (≈52 mm) gauge size for aftermarket pods or custom dash installations. 

• Digital stepper motor movement for precise and reliable readings. 

• Includes 1/8″ NPT temperature sender and adapter fittings (commonly 3/8″ & 1/2″ NPT) and wiring harness in most kits. 

• Suitable for 12 V and 16 V negative-ground electrical systems.

Compatibility & Installation Notes

• Requires a 2-1/16″ gauge hole (≈ 52 mm) in the dash or gauge pod—verify your panel cut-out.

• Sender must be installed into a compatible transmission or fluid line port (1/8″ NPT) and sealing must be secure to ensure accurate readings.

• Ensure the wiring harness and vehicle electrical system (12/16 V negative ground) are compatible.

• Because transmission fluid temperature often correlates with load (towing, heavy use, etc.), this gauge is especially beneficial in high-stress or modified applications.
