Transmission error codes P1745 and a PO869

Good afternoon,

This 869 code is for the line pressure is too high. I attached the possibilities below for you to view. It could be an electrical failure but needs to be checked.

You will need an advanced scan tool that can read the transmission and monitor the pressure and the sensor to see if there is a signal to the TCM.

1745 is related to the 869 code.

It could be dirty fluid in the transmission, valve body issues, wiring issues or the solenoid pack that is defective. They all need to be checked t find the failure.
