AutoMeter - 2-1/16" Transmission Temp Gauge (100-260F) Digital Stepper Motor Version - 3657

Transmission fluid temperature is one of the most critical factors in the life and performance of your automatic transmission. With the AutoMeter 2-1/16″ Transmission Temp Gauge reading from 100-260 °F, you’ll have real-time data to know when to downshift, ease off, or monitor heavy load conditions like towing or boosted applications.

This version uses a digital stepper motor meter movement for fast and precise needle response. The kit includes a high-accuracy 1/8″ NPT temperature sender, wiring harness, adapter fittings (3/8″ and 1/2″ NPT in many kits) and mounting hardware for simplified installation.

The gauge features white “through-the-dial” LED lighting for excellent visibility in all conditions, and functions on 12 V and 16 V negative-ground systems, making it suitable for high-performance, racing, and heavy-duty applications.

Key Features

• Range: 100-260 °F transmission fluid temperature

• Digital stepper motor needle movement for precise readings

• Includes 1/8″ NPT sender and adapters (commonly 3/8″ & 1/2″)

• White LED illumination through the dial

• Compatible with 12 V and 16 V negative-ground systems

• Built for performance, racing, heavy-duty and towing applications

Compatibility & Installation Notes

• Fits standard 2-1/16″ (≈ 52 mm) gauge mounting holes.

• Requires proper installation of the temperature sender into a suitable port (1/8″ NPT) and correct wiring of the included harness.

• Because this is a precision instrument for transmission monitoring, ensure your transmission cooler, line routing, and fluid are suitable for the temperature range.

• Verify your vehicle’s electrical system is negative-ground and within the 12–16 V range for optimal compatibility.

Warranty & Support

Final Sale Item. CANNOT be RETURNED. Before purchase and installation, verify the gauge range (100-260 °F) matches your expected transmission fluid temperatures and that the mounting size fits your dash or pod.
