Product Details

The AutoMeter Ultra-Lite Mechanical Transmission Temperature Gauge provides precise, real-time monitoring of transmission fluid temperature—the single biggest factor affecting automatic transmission lifespan. Whether towing heavy loads or running high-performance builds, knowing your exact trans temp lets you make critical decisions about when to downshift or ease off the throttle before damage occurs.

Key Features:

  • 2-5/8" diameter gauge with 140-280°F temperature range
  • Mechanical movement with 8-foot capillary tube for accurate, direct temperature measurement
  • No electrical connection required—operates purely mechanically for universal compatibility
  • Traditional incandescent lighting illuminates dial perimeter in white
  • Brushed aluminum Super Bezel with silver dial and fluorescent red pointer
  • Flat, clear lens for easy reading in all conditions
  • Race-proven mechanical design delivers reliability even in harsh environments

What's Included:

  • Transmission temperature gauge with 8-foot capillary tube
  • 1/2" NPT adapter for installation in transmission pan
  • Bulb and socket assembly with red and green bulb covers
  • Complete mounting hardware and detailed installation instructions

The included 1/2" NPT adapter installs directly into your transmission pan for accurate fluid temperature readings. An optional transmission cooler line manifold adapter is available separately for alternative mounting locations. Compatible with any street or race vehicle—no power source needed.

It was very good

Pleased

.

Great fast shipping.

Good experience

had a glitch on the site but overall pretty satisfied

Best Price I could find, fast shipping. I shall return!

Lowest prices around the web and excellent customer service. The only real issue was the wait between placing the order and when it was shipped. Took 4 days but I chalk that up to the large amount of business they due to their prices being so competitive. For the lowest prices that I've seen I didn't mind waiting a bit longer!

Very fast shipping and product was secure in package to avoid damage....will be ordering from autoplicity again for sure. Also the price could not be beat.

Awesome! Would do business with again.

Superb company! Autoplicity had the lowest price, shipped it quickly, and it was exactly as advertised - couldn't ask for better results!

Fast shipping. And great cust service.
