Code 841 ???
 

I getting a code 841 (Transmission Fluid Pressure Switch A) My 2005 Dodge Ram 1500 5.7 has just started shutting off at a full stop. Im getting the code 841 so does it need the pressure switch replaced? and if so where is switch A located? and what is the part number for it? I would appreciate any instructions on how to replace it if thats what I need to do. Thanks to all who can help me. Much appreciated.
