GlowShift Transmission Pan Temperature Sensor Thread Adapter Kit — 1/8-27 NPT Nickel‑Zinc Carbon Steel

GlowShift's Transmission Pan & Oil Pan Temperature Sensor Thread Adapter is a carbon-steel kit that creates a sealed 1/8-27 NPT port in your transmission or oil pan to accept a temperature sensor or act as a drain plug when not in use.

This compact adapter kit gives you a simple, durable way to add a temperature sensor to pans that lack a factory port. Built from nickel-zinc coated carbon steel, it installs in minutes with the included nylon washer, nut and 1/8-27 NPT plug. GlowShift also supplies step-by-step instructions and a one-year limited warranty plus free lifetime technical support to help during installation and use.

How does this adapter let me install a temperature sensor in my pan?

The adapter provides a female 1/8-27 NPT threaded port that accepts common temperature sensors. You drill and tap or replace an existing plug location, secure the adapter with the included nut and nylon washer, and thread your sensor directly into the port for a leak-resistant fit.

• 1/8-27 NPT female thread accepts widely used sensor sizes
• Nylon washer helps maintain a fluid-tight seal
• Includes nut for secure mechanical mounting
• Step-by-step installation guide reduces guesswork

Can I leave the adapter in the pan without a sensor installed?

Yes—the kit includes a 1/8-27 NPT plug that screws into the adapter if no sensor is fitted. That plug serves as a drain-plug-style closure and prevents leaks until you decide to add a sensor, so you don’t have to remove the adapter later to maintain fluid integrity.

• Supplied NPT plug blocks fluid when sensor is absent
• Plug threads match the adapter thread for a secure seal
• Allows pre-installation now and sensor addition later

What materials and coatings are used, and why do they matter?

The adapter is machined from carbon steel and finished with a nickel-zinc coating to resist corrosion from oil and transmission fluid. Those materials provide the necessary strength for repeated sensor installation and removal while protecting the metal in harsh under‑vehicle environments.

• Carbon steel core for mechanical durability
• Nickel-zinc plating improves corrosion resistance
• Construction suited to oil and transmission fluid exposure

What tools and steps are required to fit this adapter?

Basic hand tools and the included instructions are all you need for most installations. Typical work involves locating or creating a compatible port, securing the adapter with the washer and nut, then threading in the sensor or supplied plug and checking for leaks.

• Drill/tap or remove existing access plug as required
• Use included nylon washer and nut for a sealed mount
• Hand-tighten sensor or plug, then torque per instructions
• Follow GlowShift's step-by-step guide for leak checks

Who is this for? This adapter kit is intended for DIY mechanics, performance tuners, and technicians who need a reliable way to add a temperature sensor to transmission or oil pans that lack a factory sensor port. It's a practical solution for anyone wanting to monitor fluid temperature or prepare a pan for future sensor installation without replacing the pan itself. Backed by GlowShift's one-year limited warranty and lifetime technical support, the kit is suitable for hobbyists and professional shops that require straightforward installation, corrosion-resistant materials, and the option to use the port as a drain plug when a sensor isn't installed.
