F-350 Trans Lock up Issues
 

2002 F-350 4X4 7.3 DIT. Trans not coming out of lock up all the time. Have Changed Solinoid Pack. Have also Changed PCM(For unrelated problem). A buddy suggested changing Torque converter as they have been known to be a problem? I'm not getting any DCT's and doen't appear to be dropping into safe mode.(OD off light not flashing). any suggestions?
