01 cummins trans shifting probs
 

Today I noticed my truck wouldnt hardly shift out of first or second gear. Once it got out of second it seemed fine until I reached a stop sign and noticed it wouldnt shift back into first. It took off in second. I checked the fluid and its fine. I have codes 0622, 0743, 1765 which are all related to the torque switch, I think, but I also have code 1762 which is governor voltage or something. Has anyone else had this same problem and what fixed it?

Yes I have a torque switch and Edge comp. No preaching please. I already went to church today.

1762 is governor pressure solenoid, the 2nd gear starts are because the thing is in limp mode.
