The two codes mentioned in the first question do not clear, however when I re ran the codes I got a high battery voltage (jump started it after bleeding the injector lines a couple days ago) and ,with the two codes that don't clear another p1693 code showed with them. I cleared the second p1693 and voltage codes and the truck drives and shifts fine now. Is there an underlying issue that would cause that? The two original codes have been on since I bought the truck but as soon as the high voltage and second p1693 code came on it wouldn't shift. I only started the truck and let it run for about 5 minutes then drove it and as soon as I realized it wasn't shifting I pulled back into the drive way and cleared the two new codes and it shifted fine. Sorry if I'm being confusing I'm not a diesel mechanic by any means IMG_0836.MOV

2000 cummins ats stage 2 trans won't shift out of first. Edge cts reads it being in second but doesn't shift out of first. p0112 (intake air temp sensor 1 circuit voltage low) and p1693 (fault in companion module) codes are present. What causes this shifting issue and how can I fix it?
