Do I need a Test port Extender on a 1998.5-2002 Dodge with the 47/48RE Transmission and why?

Yes, a ⅛-27 NPT test port extender is required when installing our sensor into a 47/48RE transmission. The reason for the extender is due to the test port location on the transmission is too shallow and could cause the internals of the transmissions to damage our sensor.
