Use this fitting when you are installing your own DIY temperature gauge to your transmission.

Note 1: Tapping these fittings straight can be challenging, be sure to take your time when starting out. The fittings are now tapped for 1/8-27 NPT. A number of clients mentioned (complained?) that it was really tricky to tap these fittings properly, and some were having to order more than one to get it right. I purchased the necessary (expensive!) machine tools to tap them straight, which takes a little more time to do, but is SO worth it.

Note 2: You may have to custom adjust the depth of my tapping to suit your specific fitting using your own 1/8-27 NPT tap.

Note 3: If you want an un-drilled fitting, please let me know by email or a message when you order. The default is to only ship a tapped fitting.

Note 4: If you are fitting a transmission temperature sensor into this fitting, make 100% sure the sender does not obstruct fluid flow. Often this means you must use a short sender and that usually also means a short sweep gauge. In the future (sometime in 2023), I may offer an elongated fitting to allow use of a long sensor... but that's a ways out right now.

suggested sensor style (I will add others in the future):
• AutoMeter #2259

Suggested Temperature Ranges:
120 - 230*F = normal
230 - 265*F = Warm
265 - 300*F = Hot

• The product photo image of the gauges was clipped from Wholesale Automatics Trans Temp sensor guide located at:
