You may not have a dedicated trans fuse, its probably tied into another circuit since a lot of stand alone harnesses consolidate wires to make the fuse box smaller. It wont go to the PCM, it is likely one of those pink wires in your fuse block. If you have a meter you can do a continuity test between the trans plug and the fuses at the fuse block to figure out which wire it is. If it was shifting before then that means it definitely was hooked up before, and something has happened. Have you checked all the fuses in the fuse box to make sure they are all good?
