P-0753 TRANS 3-4 SHIFT SOLENOID/TRANS RELAY CIRCUITS
When Monitored: Continuously with the key on.
Set Condition: This code is set if the voltage detected on the 3-4 Shift Solenoid Control
Circuit at the PCM is different than the expected voltage.
P-1763 GOVERNOR PRESSURE SENSOR VOLTS TOO HIGH
When Monitored: Continuously with the key on and engine running.
Set Condition: The voltage from the Governor Pressure Sensor is above 4.89 volts for 8.5 seconds.
The solenoids are located on the valve body so the trans pan needs to be removed to access them.
They do not show a pic of its location, othewrwise I would include it here for you.
The governor pressure sensor and pressure solenoid are generally replaced at the same time.
Here is a pic showing their location on the valve body. The shift solenoid is the only other electrical piece on the valve body........but does not appear in any pic.
