Is this procedure good for my truck, 03 Dodge Cummins? I am getting P0123 in the PCM and is in limp mode. For awhile after warmed up would drive ok. Was shifting in all gears, then it stayed in limp mode and local mechanic grounded the trans relay in the fuse box, then it shifts but no OD Now stays in limp mode when not grounded in fuse box. Replaced APPS with TIMBO's APPS at http://www.dodgecumminsapps.com/index.html, Made no difference.

I burnt ground wire to pcm, replaced by shade tree mechanic who also broke the pcm by exploring inside. $400 replacement. After extended time with no results from shade tree guy I let sit. Then a place called Promotive in Visalia said take to dealer because it must be software problem. $85. Then dealer in one day replaced middle connector $300. So I am in the red trying to avoid dealer.. Should have started with dealer.
