Based on our research, Glowshift has determined the 68RH/RE transmissions are not equipped with a test port location. Due to there not being a test port location, this leaves us with only two installation methods.
1. Cooler Line: This method will give you the reading of the fluid exiting the trans and going to the cooler to be cooled down before returning to the transmission. Here is the adapter you will need for this installation Method: Transmission Line T-Fitting Adapter for Dodge Ram Cummins
2. Sensor into Transmission Pan: This method would be to put the temperature sensor adapter kit into 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.
