After changing the Trans filter and fluid, I get a fault code p1860 : Torque converter clutch pulse with modulator solenoid circuit. Could it be possible I damage one of circuits while trying to remove the oil pan?

the pwm tcc solenoid is in the valve body next to the lockup solenoid. its possible that it got unhooked or damaged changing the filter.
