GlowShift’s 3/8” Transmission Line T-Fitting Adapter allows you to install your 1/8-27 NPT transmission temperature sensor to the 3/8” transmission cooler feed line for extremely accurate readings directly from the source. This Transmission Line T-Fitting Adapter is compatible with any 1999-2007 Ford Super Duty truck with a 3/8” transmission line and comes included with (1) T-fitting housing with 1/8-27 NPT sensor port, (2) compression nuts, and (4) cutting rings that ensure a tight, leak-free seal. This transmission line T-fitting adapter is manufactured from high quality carbon steel with a tough, nickel plated zinc coating that prevents rust over longtime use. GlowShift includes detailed installation instructions, free lifetime technical support and a one year limited warranty with each purchase.

Note: Be sure to measure the circumference of the Transmission Cooler Line. A circumference of 1 1/4" is needed for the 3/8" Transmission Line T-Fitting to properly fit.
