2-1/16 E/S Trans Temp. Gauge - 100-260

The AutoMeter 2-1/16 inch Transmission Temperature Gauge (Model 5658) is a precision electric transmission temperature gauge designed for drivers who need real-time monitoring of transmission fluid temperature. This full-sweep analog gauge displays temperature readings from 100 to 260 degrees Fahrenheit, giving you continuous visibility into one of the most critical parameters affecting transmission longevity and performance. The black face with easy-to-read numerals and a smooth pointer movement provides clear readings at a glance, whether on the street, dyno, or track.

The 2-1/16 inch diameter housing fits standard automotive gauge clusters and aftermarket dash pods, making installation straightforward for most custom builds. The electric sender design eliminates mechanical cable routing and offers faster response time compared to mechanical gauges, so temperature spikes register immediately on the dial. The 100–260°F range covers both cold-start conditions and extreme operating temperatures, making this gauge suitable for stock applications, modified vehicles, and high-performance transmissions running elevated fluid temps under load.

Transmission temperature monitoring is essential for anyone serious about drivetrain health. Overheating degrades fluid viscosity and reduces clutch pack friction, leading to slippage, delayed shifts, and eventual failure. Conversely, temperatures below 140°F indicate the transmission hasn't yet reached optimal operating viscosity. This AutoMeter gauge lets you catch both conditions early. It's commonly installed on manual transmissions, automatics, and builds using performance converters, coolers, or modified tuning where stock temperature monitoring is inadequate or absent.

AutoMeter's Elite Series gauges are known for accuracy and reliability in demanding automotive environments. The full-sweep movement means the needle travels smoothly across the entire dial range, providing precise feedback rather than clustered readings. With a compact 0.85 lb footprint and dimensions of 4.8 x 4.5 x 5.1 inches, installation into existing gauge clusters or custom panels is efficient and unobtrusive.
