be related to the throttle body, i had it apart when i changed the thermostat

Question

i replaced the front o2 sensors and thermostat due to codes related, had to remove intake manifold so i replaced all gaskets, took apart throttle bode valve to clean it, car now displays a p0770 code for transmission fault, could tthe trottle body be related to the problem

Answer 1

P0770 Shift solenoid E malfunction

This is for the TCC (torque convertor clutch) solenoid . The Cadillact CTS does not use P0770 in any of there code definition,  and this would not be related to the throttle  body cleaning or the 02 sensor replacement, it would be related to the engine temperature sensor or the thermostat .
