Hello all, hoping to get some help here. Story, is I had a converter fail on me. I rebuilt the trans and a new converter. Upon installation and first drive. I have the above codes. I've already verified that transmission harness is good. TSS + OSS sensors both ohmed within specification. The TSS reads in reverse and manual first. Manual 2nd isn't doing anything at all, no reading and no movement. In drive, after clearing codes TSS will read for a split second and the cut off. Have a feeling trans needs to come out again. Have pulled the pan and fluid looks good. Shifts good into all 4 gears, and downshifts through gears.
