These codes are all for the transmission pressure sensor or circuit. I have seen the TIPM go out on these vehicles which will cause this issue. Here is the location of the module. I would remove the electrical connectors and check them for water damage, overheated. I have included the transmission wiring diagrams so you can see how the system works.
The codes you provided are diagnostic trouble codes (DTCs) related to vehicle issues. Here's what each code represents:
P1745: This code indicates a problem with the transmission line pressure solenoid/pressure switch circuit.
P0869: This code indicates a problem with the transmission fluid pressure. It is related to the line pressure sensor circuit.
P0933: This code indicates a problem with the hydraulic pressure sensor circuit in the transmission.
P0934: This code also relates to the hydraulic pressure sensor circuit
Let's check the m28, m33 and m15 fuses for power in the under-hood fuse panel (TIPM) The transmission control relay (on pcb) is not serviceable.
