Do I need a Stubby sensor when installing a Transmission temperature sensor into the test port of my 2000-2006 Silverado/Sierra with a 4L60e/4L80e?

If you have a 2000-2006 Silverado/Sierra with a 4L60e, our stubby sensor is needed when installing into the test port location. If you are going to install the sensor into the Transmission cooler line and or the transmission pan, the stubby sensor is not required. 

*A Stubby sensor is not required if you have a 4L80e Transmission application.*
