Test Port: This port was designed for transmission companies to test line pressure inside the transmission. Most test ports are the same size as our sensors, but some ports will require a thread adapter. The 1992-1997 F-Series transmission test port is the same thread size as our sensors, and will not require and additional adapters.
Cooler Line: Another method of installation would be to install a T-Fitting onto the cooler line to get a reading of the fluid going to the cooler. With this method, we do offer three different sizes "T" fittings. We offer a ⅜” T-Fitting or ½” T-Fitting, it would depend on the year and option of the vehicle the cooler line will be different. We highly suggest customers check the outer diameter of their cooler lines to determine what T-Fitting will work best for their application. This method will give you the reading of the fluid exiting the transmission and going to the cooler to be cooled down before returning to the transmission.
Sensor into Transmission Pan: The last method and typically the most involved. This method would be to use the Temperature Sensor Adapter Kit to the transmission pan and install the sensor directly into the pan for a reading. For this method, it will require you to drain all the fluid in the transmission, remove the pan, clean the pan, drill a hole, add the adapter, and then re-install the pan with new gaskets. It is the most involved method, but this method gives you a reading of the fluid sitting in the pan of the transmission.
