Code P0740

[JET]

My 2014 Ram with 106,500 miles on it is setting code P0740. "Torque Convertor Clutch Circuit / Open". Anyone have any ideas before I take it to the dealer?

Thanks very much.

Assuming you have 68RFE. You need a scan tool that can monitor torque converter slip to properly diagnose.

sag2, thanks for the response. I have an Android tablet with AlfaOBD software and OBDLink LX adapter. I don't know if it has that capability or not. I will have to do a little research. I know it did allow me to change my tire pressure settings so that I don't have to run so much air in the tires when I am not towing.
