Glacier Diesel Power 2003-2018 Dodge Ram 48RE & 68RFE Transmission Temperature Sender Manifold | Accurate ATF Temperature Monitoring
Description
Monitoring transmission temperature is one of the best ways to protect the life of your automatic transmission—especially when towing, hauling, or running increased horsepower. However, where you measure transmission temperature is just as important as the gauge itself.
The Glacier Diesel Power Transmission Temperature Sender Manifold is designed for 2003-2018 Dodge Ram trucks equipped with 48RE or 68RFE automatic transmissions. This billet manifold installs directly into the transmission cooler feed line, allowing you to install virtually any aftermarket transmission temperature sender using the integrated 3/8" NPT port and included 1/4" NPT reducing bushing. By monitoring the temperature of the transmission fluid as it leaves the transmission and enters the cooler, you'll see the actual operating temperature of the transmission before the cooler has a chance to lower it.
Whether you're towing heavy loads, daily driving, or building a high-performance diesel truck, accurate transmission temperature monitoring can help you identify overheating conditions before expensive damage occurs.
Features
- Fits 2003-2018 Dodge Ram 2500 & 3500
- Compatible with 48RE and 68RFE automatic transmissions
- Precision-machined billet aluminum manifold
- 3/8" NPT sender port
- Includes 1/4" NPT reducing bushing
- Accepts most aftermarket transmission temperature senders
- Installs in the transmission cooler feed line
- Simple installation by removing approximately 1" of transmission cooler line
- Reusable, corrosion-resistant design
Why Sender Location Matters
Many factory transmission temperature sensors monitor fluid after it has already traveled through portions of the cooling system or inside the transmission pan. While these locations provide useful information, they don't always reflect the hottest fluid leaving the transmission.
Installing the sender in the cooler feed line allows you to monitor transmission fluid immediately after it exits the transmission. This provides a faster and more accurate indication of transmission workload because the cooler has not yet reduced the fluid temperature. It's one of the preferred locations used by many transmission builders and performance enthusiasts for monitoring transmission health.
Transmission Tech Tip
Heat is one of the biggest enemies of any automatic transmission.
Consistently elevated transmission temperatures accelerate fluid breakdown, reduce lubrication, and shorten the life of internal seals, clutch material, and friction components. Monitoring transmission temperature allows you to recognize excessive heat before it becomes an expensive repair.
If you regularly tow heavy trailers, climb long grades, or drive in hot climates, a transmission temperature gauge should be considered essential equipment. Many owners also pair temperature monitoring with deeper transmission pans or upgraded coolers to help maintain consistent operating temperatures under heavy loads.

Transmission Failure Point
Most automatic transmission failures don't happen without warning—they happen after the transmission has spent thousands of miles operating at elevated temperatures without the driver realizing it.
By measuring fluid temperature before it enters the transmission cooler, this manifold provides a more accurate picture of how hard your transmission is working. That information allows you to adjust driving habits, reduce towing loads when necessary, or identify cooling system issues before excessive heat leads to clutch wear, fluid degradation, or internal component failure.
