Pressure Test Port Location
WARNING: This page is about a different car, the 2016 RAM 3500 HD. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The pressure port plugs are 1/2 x 20 UNF thread, with O-ring.
A line pressure test is performed to check the performance of the oil pump, to check the functionality of the control valves, and to check parts for oil leakage. The line pressure port (1) is located on the lower left side of the transmission case.
