I need help D: I was driving about 35 mph the other day and out of nowhere my truck downshifted and went into limp mode and I got a transmission malfunction error on the dash along with the O/D light flashing. My truck is an 04 5.4l 4x4. I thought it might just be the shift solenoid and when i checked my edge tuner for diagnostics there was a **** load of codes that came up and I thought they were all related to it. So i changed out the shift solenoid pack, and the TCC solenoid and started her up and its still in limp mode.

these are the error codes I have now

P0141 HO2SHTR12 Heater Circuit Malfunction
P0161 HO2SHTR22 Heater Circuit Malfunction
P0740 TCC Circuit Fault
P0743 TCC Circuit indicated the solenoid as ON low voltage when requested OFF high voltage
P0748 Line pressure control electrical malfunction
P0755 Shift Solenoid #2 Electrical Fault
P0758 SSB Control CIRCUIT Electrical Failure
P0962 LPC Control Circuit Low



Update before I post, I found the shift solenoid fuse and it was blown but I dont have a spare on me. Does this fuse power the TCC too? or is the shift solenoid not coming affecting the TCC? Sorry I am a noob and I dont know much about transmissions

where can i check for a short in the shift solenoid? All I saw was a plastic wiring harness what wire would I follow to find a short?
