I have a 2012 Quad cab flat bed that has had a 2014 6.7 cummings with 2014 tranny. The engine has a chip on the motor. I have had a new shift module put on the tranny. Currently it is in a default mode so it will go into reverse and fourth gear. CAn I take it off and have the dealer flash the shift module or can I do this myself. I am using a trouble shooting program call Auto Enginuity. It works well on my Ford F350 2004.
