I'm having shifting issues. I replaced the common pressure solenoid and now I can manually shift through the gears, but it won't shift it's self. And if I just shift it into drive, it takes off in second gear.
I'm getting these codes.
P0753 Shift Solenoid A electrical
P1764 Governor pressure sensor low
P1765 Transmission 12 voltage supply relay control circuit

 

Are you getting 12 volts to the trans when the engine is running?

Did you replace the pressure sensor as well? Or just the solenoid?

Should be a 5 volt feed to the trans as well.

 

Yes. I replaced the sensor and solenoid. I will check voltage to trans next. Thanks
