6.0 problems

New member and needing advce.

I have a 2004 f350 6.0 it starts easy and idles but when I take it out of park or neutral it dies a quick and hard stop.

There is no codes on my AE. It started and ran fine until I let it sit a couple of months when this pandemic started. I was going to take it and have it inspected and tags renewed when it started doing this.

I though maybe the wiring harness to tranny had gone gad or was shorting out but I pulled the harness off and tore it apart and inspected each wire and could find not shorts or opens. Put it back in and the same thing.

I have had one person tell me the gear sensor in the tranny may be bad but did not know how to check it. Then I had one tell me the torque converter had froze up still no way to check it.

Has anyone ever had this kind of problem?

Thanks

Alton

I haven't had any issues like that with mine but like any 6.0 the first strep is a thorough scan. It needs the Ford software to do it. I start with my mechanic that has all the needed scanning equipment if something acts up on mine.
